28 ANALYTICAL PROCEEDINGS, JANUARY 1985, VOL 22 I tquipment News Mass Spectrometer The PlasmaQuad inductively coupled plasma source instrument offers detection limits as low as tens of parts per trillion and allows the entire periodic table to be scanned in milliseconds. The low detec- tion limits are particularly relevant for environmentally important elements such as mercury, cadmium, lead and uranium. Isotope ratios can be measured directly and isotope dilution analysis gives ex- tremely accurate results. VG Isotopes Ltd., Ion Path, Road Three, Winsford, Cheshire, CW7 3BX. Spectrophotometer Graphics A Lambda 5 graphics update kit is avail- able for existing Lambda 5 ultraviolet - visible spectrophotometers. As many as six full range (190-900 nm) spectral files can be stored and can be viewed on the screen or copied on the instrument’s plotter. Subtraction and addition of spec- tra or multiplication by a factor can be performed. First to fourth derivative spectra can be calculated and displayed from percentage transmittance and ab- sorbance data stored in the memory.The graphics feature is compatible with the six cell programmer so that repetitive scans can be displayed for comparison before the information is copied on to the printer - plotter. Perkin-Elmer Ltd., Post Office Lane, Beaconsfield, Buckinghamshire, HP9 1QA. Microanalysis The Edax 9900 is a microanalytical system from Edax International (Prairie View, IL, USA), available from Philips, based on an energy-dispersive X-ray spectro- meter. The system is designed for use with electron microscopes (SEMs or STEMS), and can collect, process, display and store a variety of signals: backscattered or secondary electrons, absorbed electron current, cathode luminescence, EDS and WDS elemental X-ray and electron energy loss spectrometry signals.Process- ing functions include signal thresholding, signal ratioing, background subtraction and deadtime correction, with advanced colour graphics. The system provides full quantitative analysis from boron to uranium. Philips Scientific and Industrial Equip- ment, 5600 Eindhoven, The Netherlands. X-Ray Spectrometers The PW 1606 simultaneous XRF spec- trometer from Philips has a 3 kW, 60 kV generator that cuts power requirements by 40% and no special cooling circuit is required. High-speed measurement of up to 28 elements is possible, and new hardware and software features combine to give a reliable system for process control, e.g., in the cement, metals, glass and mining industries.The PW 1404 sequential XRF spec- trometer has multilayer “crystals” giving enhanced sensitivity to light elements down to C and B. Side-window X-ray tubes are used, with a new dual-anode tube that allows the use of a single X-ray source. New generation software pro- vides qualitative and quantitative capa- bilities, including colour graphics. Philips Scientific and Industrial Equip- ment, 5600 Eindhoven, The Netherlands. X-ray Spectrometer Improvements Replacement of the conventional TIAP crystal with PX-1 gives improved light- element performance in the makers’ PW 1400 sequential X-ray spectrometer. Called a multilayer, PX-1 is created by the deposition of alternate layers, only nano- metres thick, of heavy and light element atoms on a silicon substrate to form a crystal-like structure that acts as an X-ray monochromator. Advantages include long-term stability, non-toxicity and reduced higher order reflections.Another development is a carbon analy- sis accessory, which includes a special monochromator and which can be attached with only minor optical and electronic modifications. The carbon analysis attachment gives an improve- ment in sensitivity of five to ten times that obtained with a normal lead stearate crystal; this is achieved using only a standard argon - methane counting gas. Pye Unicam Ltd., York Street, Cam- bridge, CB1 2PX.Chromatography Detector Data System The PU 4850 data station, complete with specially written software, is for use with the makers’ PU 4021 multi-channel ultra- violet LC detector. It allows hundreds of spectra to be stored in a single chromato- graphic run. There are two modes of operation. The chromascan mode enables storage of complete ultraviolet or visible spectra at a programmable rate to a maximum of Is-’. The on-line VDU displays the results as a three-dimensional view of the sample and this can be displayed from a number of different viewpoints, ensuring that no data are hidden. The second mode involves selec- tive storage of spectra from a chromato- graphic run. Parameters can be set to enable a spectrum to be acquired at peak apex, at inflection points, at a pre-set retention time, or manually at any time.These peak detection algorithms can be run concurrently, providing data for peak authentication and for monitoring peak purity . Pye Unicam Ltd., York Street, Cam- bridge, CB1 2PX. Graphite Tube for Atomic- absorption Spectroscopy The TPC (Totally Pyrolytic Cuvette) is made completely from pyrolytic carbon and achieves the prime requirements of low porosity and low carbide formation, giving a longer analytical lifetime than existing tubes. An example of its per- formance is in results for manganese, where the TPC can still be used after 2200 firings without any significant loss in performance, whereas a pyrocoated tube lasts approximately 800 firings before performance deteriorates. Pye Unicam Ltd., York Street, Cam- bridge, CB1 2PX.Gas Chromatograph The HNU GC 421 features multi-ramp temperature programming and offers the choice of FID, PID and far UV detectors. A dual-column instrument, it accepts any combination of packed or capillary col- umns and it can incorporate up to three integrated detectors; these are easily demounted to add auxiliary detectors. Other features include an on-column injection system for packed columns, a three-position universal detector base, an 1100-in3 dual-column oven, an autozero facility and an STD bus, which simplifies the addition of accessories. Analysis Automation, Southfield House, Eynsham, Oxford, OX8 1JD. Gas Chromatograph The PU 4550 high-resolution separation station can be used either as a stand-alone or connected to an existing data system or video chromatography control unit.Dual packed-column injectors are provided and can easily be replaced by one of three capillary injectors. A Grob-type splitless injector and inlet splitter are available for use in automatic operation. A range of five detector types, all suitable for use with capillary columns, is available and the oven accepts two detectors simul- taneously. Pye Unicam Ltd., York Street, Cam- bridge, CB1 2PX.ANALYTICAL PROCEEDINGS, JANUARY 1985. VOL 22 29 Gas Chromatograph The PU 4900 is designed for both capillary and conventional use and has been opti- mised for capillary columns and new capillary injectors. The column oven, with a slide-out assembly for easy access, has an aerodynamic air flow path to ensure that the column is in a thermally stable zone with minimum gradients, so that repeatability is achieved without peak distortion or splitting.Also, the controlling resistance thermometer is next to the column, resulting in an excep- tionally low thermal lever, minimising the effect of ambient temperature. For multi-dimensional chromatography there is a unique “mirror image” satellite oven with simultaneous but independent control and the sample can be transferred directly from one to the other. A plug-in interface oven with independent control eliminates loss of sample or resolution. Other features are comprehensive gas control, with up to six pressure regulators and twelve solenoid valves, automatic operation from sample injection to calcu- lation of results, multiple detector opera- tion with up to three detector systems operating simultaneously with full data handling facilities for each channel, a graphics capability via an integral display unit and data storage using two floppy disks.Pye Unicam Ltd., York Street, Cam- bridge, CB1 2PX. Gas Chromatographs Nine “routine B” versions of the Model 8300 instrument are announced. The 8300B series are configured for one detec- tor only. FID, ECD and NPD packed and capillary versions are available; full screen graphics and data handling facili- ties are optional accessories. Single col- umn temperature programming using automated bleed compensation is stan- dard. The 8300B instruments are compat- ible with the same range of accessories as the Model 8300; these include the AS- 8300 autosampler, the HS-6 headspace sampler and the ATD 50 automatic thermal desorption system.Perkin-Elmer Ltd., Post Office Lane, Beaconsfield, Buckinghamshire, HP9 1QA.
