Since this method was published the Sub-committee’s attention has been drawn to the fact that on certain types of feed the aqueous acid extraction procedure used does not adequately extract the drug from the feed. This situation is now under active consideration and in the meantime it is recommended that if a low recovery of the drug by the polarographic method is suspected one of the published alternative methods should be used.

April 19701 DETERMINATION OF FLUOIIINE AND FLUORIDES 71 The Determination of Fluorine and Fluorides 'l'lie following is a summary of one of the papers presented at an Ordinary Meeting of the Midlands Section held on December loth 1969 and reported in the January 1970 issue of Proceedings (p. 1). The Determination of Fluorine by Neutron-activation Analysis BY P. G. JEFFERY AND J. M. BAKES (Warren Spring Laboratory Steveitage Herts.) DR. JISPFERY reviewed briefly the types of reaction that can occur when stable atoms are subjected to irradiation by charged particles and by neutrons. Sources of neutrons were explained and compared. Their utility in determining fluorine was then examined reaction by reaction in the light of competing reactions likely interferences and convenience in use. TABLE I SOME REACTIONS OF FLUORINE-19 E and t j of product Reaction Neutrons I h 't 19F (n,r) 2oF .. . . Thermal 1.6 MeV 11 seconds 19F (n,2n) ISF . . . . Fast (0.51 MeV) 110 minutes 19F (n,p) 1 9 0 . . . . Fast 0.2 and 1-37 MeV 29 seconds 19F (n,cc) lGN . . . . Fast 5 to 7 MeV 7-35 seconds The (n,y) reaction gives fluorine-20 which decays by both fl and y-emission to give neon-20 a stable isotope. For this reaction thermal neutrons are used either from a nuclear reactor or from a fast-neutron source that have been suitably moderated. The short half-life of fluorine-20 does not permit chemical separation to be made and the 1.6-MeV energy of the product nuclei is in a region in which interferences from other elements can be expected e.g. from aluminium-28 with E = 1.78 MeV. Aluminiuni-28 is produced from aluminium-27 by an (n,y) reaction and from silicon by an (n,p) reaction.A sensitivity of less than 1 p.p.in. has been reported for this reaction but this is unlikely to be achieved in practice and 50 p.p.m. is probably a more realistic limit for the determination of fluorine in many materials. By contrast the (n,2n) reaction producing fluorine-18 can be used in conjunction with the chemical separation. However this is not always necessary and this reaction has been used without a separation for the measurement of fluorine in ores and other similar materials. Fast neutrons from a Cockcroft - Walton generator were used to irradiate the sample for 5 minutes which was then allowed to cool for 60 minutes after which the 0.51-LClleV positron emission was counted for a further 5 minutes.The 60-minute cooling period is necessary to allow other short lived positron emitters to decay. The sensitivity of this reaction was not determined but appears to be about 0.2 per cent. of fluorine. Also requiring fast neutrons the (n,p) reaction produces oxygen-19. Oxygen-19 is listed with two activities a t 1-37 MeV and at 0.2 MeV. The 1.37 MeV represents only a small proportion of the total output and if this reaction is used the 0-2-MeV peak must be measured. I t is not possible to use this reaction for determining fluorine in ores rocks and minerals as there is considerable interference from other elements but it can be used to determine fluorine in certain simpler materials. For example pure metals produced by electrolysis of a fluoride melt invariably contain a small amount of fluorine which can rapidly and readily be determined by using this (n,p) reaction. The sensitivity is about 0.1 per cent. of fluorine. The (n,cc) reaction giving nitrogen-16 is a more convenient reaction to use as the half-life of 7-35 s is ideal for fast-neutron activation analysis and the energy of the product nuclide 5 to 7 MeV is in a region in which interference from all other elements is virtually absent. Interference from oxygen which produces nitrogen-16 by an (n,p) reaction is avoided by using an isotopic neutron source the energy of whose neutrons is below the threshold limit for the 160 (n,p) 16N reaction. This is the most promising reaction for industrial use enabling fluorine to be determined simply easily and cheaply and every few minutes if necessary.

DATA RECOVERY EQUIPMENT IN AUTOMATIC ANALYSIS [Yroc. SOC. A rzalyt. Chem. Data Recovery Equipment in Automatic Analysis The following is a summary of one of the papers presented at a Meeting of the Automatic Methods Group held on November 13th 1969 and reported in the February 1970 issue of Proceedi.tzgs (p. 26). Gas-chromatographic Data Recovery by Computer BY J. G. LYONS (Unileaev Research Laboratory Port Sunlight Cheshire L62 4XN) THE use of gas chromatography for quantitative purposes has increased several-fold in the last few years. This has led to the need for integration aids which range from the simple mechanical type for example the ball and disc through electronic integrator - tape recorder April 19701 ELWELL AWARD PRESENTATION MEETING 73 combinations to the full “on-line” computer system.The more sophisticated integrator systems do however offer much more in their capacity for labour-saving when used in conjunction with computers. These cornputerised systems can be divided into three basic types- (i) Electronic integrators “on-line” to a computer ; (ii) Electronic integrators “off-line” to a computer; and (iii) The fully sophisticated “on-line” computer systems. The first type of system consists of either up to about 10 integrators interfaced to a small (8K words) computer or an integrator expanded by the use of magnetic tapes connected and controlled by a small (4K words) computer. This arrangement tends to be restrictive in the number of peaks and/or methods that can be handled without a further backing store-which of course increases the price.The computer is here dedicated wholly to operation of the system. In order to use the second type of system electronic integrators “off-line” to a computer several manufacturers are now offering punched paper tape and print-out via a teletype unit as an alternative to the integrator printer. The paper tape can then be fed into a computer for final calculation. The teletype associated with the integrator can become a remote terminal to a computer so that the integrals can be read into the computer and calculated. The computer in this system can of course be used for other purposes when it is not handling gas - liquid chromatographic results. With fully “on-line” computer systems the various hardware configurations usually have a central processor of at least 8K words capacity with some fast-access backing store. The analogue input is however the key to the whole system. This usually comprises an analogue-to-digital convertor with some ranging device to give a dynamic range of usually lo6 and a multiplexer of usually 200 points per second programmed to give varying sampling speeds for each gas - liquid chromatographic input. Each chromatograph is equipped with a hardware filter variable between 2Hz and IOHz and a control unit. Chromatograph-to- computer distances seem to have a maximum unamplified distance of about 1200 feet. The software packages available vary but all produce reasonably good results. The systems are expensive but their “pay-back” period in terms of labour saving is surprisingly short 2 to 4 years depending on the laboratory environment.

April 19701 ELWELL AWARD PRESENTATION MEETING 73 Elwell Award Presentation Meeting The following are summaries of two of the papers presented by finalists at the Elwell Award Presentation Meeting held on January 15th 1970 and reported in the March issue of Proceediitgs (p. 43). The Use of Acid Association Constants of o,o'-Dihydroxydiphenyl Sulphides and Metlianes in Selecting Buffers to effect their Electrophoretic Separation; The Separation of Bithionol Fenticlor and Hexachlorophene By A. GRAY (Department of Chemistry Loughborough University of Technology Loughbovough Leicestewhive) THE acid association constants and formation curves of bithionol fenticlor and hexachloro- phene have been determined and used to select buffers to effect the electrophoretic separation of these compounds.Buffer solutions were prepared in 3 + 1 v/v ethanol - water and cellulose acetate membranes were used. Optimum electrophoretic separation was obtained in a buffer solution of pH 6.3. A detailed account of this work extended to include dichlorophene tetrachlorophene bronichlorophene and 4-hexylresorcinol is to be published. 74 OBITUARY [Proc. SOC. A72nlyt. Cl’zeY.Pl. The Determination of Tungsten in Steels BY D. R. MARRIOTT (Department of Chemistry Loughborough Universit-v of Technology Loughbovough Leicestevshive) The historical development and present methods for the quantitative determination of tungsten in steels have been briefly reviewed. The use of heteropoly acids in the analysis was examined and found unsatisfactory. The determination of tucgsten by a thiocyanate method incorporating stabilisation of the colour complex as an onium salt was assessed modified and adopted for use with steels. This method is capable of analysing accurately and precisely steels containing between 0.01 and 25 per cent. of tungsten.

74 OBITUARY Obituary SIR GEORGE HAROLD LLOYD- JACOB WHEN Mr. Justice Lloyd- Jacob a judge of the Chancery division of the Royal High Court died suddenly from a heart attack a t the age of 72 the Society for Analytical Chemistry lost a great friend who was always prepared to give the Society time and who took great interest in its activities. George Harold Lloyd- Jacob originally intended to take up chemistry as a career but as the result of a serious arm wound while fighting in the Royal Flying Corps in the first World War he turned to the law and made a great name for himself in the patent field. Indeed he was almost the last of that outstanding group of patent counsel who dominated the courts after 1918. He was born in 1897 and was educated at Southgate Christ Church Oxford and Kings College London He was called to the bar by Middle Temple in 1923 took silk in 1945 and became the first judge to be appointed to the Chancery division to deal with patent cases.His ability enabled him to serve on many important committees and commissions. In recent years in an exceptionally important patent case heard by him (49 days) in which a great sum of money was involved the defendants (Rolls Royce) insured his life for a large sum of money (said to be Q00,000) until the end of the action as the cost of re-hearing which would have occurred from his death would have been so serious. Unfortunately he had not delivered judgment in another long and important case he had just heard when he died. His death was especially sad as he was looking forward to his year of office as Master Treasurer of the Middle Temple in 1970.However as far as the Society is concerned his interest in us really dated from the time of the writer’s presidency (1953 and 1954). Although an Analytical Methods Committee (A.M.C.) existed before that period the turning of the Society into a purely learned body for the promotion of Analytical Chemistry necessitated changes in the structure and activities of the A.M.C. Money was raised from industry and to administer this a Trust Fund called “The Society for Analytical Chemistry Analytical Methods Trust Fund” was formed and after some discussion Sir George Lloyd-Jacob kindly consented to accept the position of Chairman of the Trustees. The success of the preqent A.M.C. stems from those changes and today it is a matter of pride that the Society amongst other things now publishes a book on recommended and recognised methods of analysis that has a world-wide reputation.The Trustees normally met in Sir George’s room at the Law Courts. His great interest in the work of the A.M.C. and his wise counsel in the administration of the Fund which relieved the Society of some of its financial problems is perhaps not as well known to members as it deserves. Those of us principally fellow trustees but including the reigning President Honorary Treasurer and the Chairman of the A.M.C. who had the privilege of serving under Sir George will always remember with gratitude the time he gave to our affairs his never failing courtesy and his wise leadership. The Society was represented at the Memorial Service by three past-presidents and trustees (Dr. K. A. Williams Mr. A. G. Jones and the writer) and another trustee the Government Chemist Dr. D. T. Lewis. Alas the Society is much the poorer for his passing. D. W. KENT- JONES
