摘要:
AbstractUse of a Hewlett‐Packard 2648 A graphics terminal connected to a HP 3354 B Laboratory Automation System for drawing polygon diagrams of chromatographic data has been investigated. The computer program is designed to reduce polygon overlapping and hiding by fully automatic parameter adjustmen

摘要:
AbstractThe technique of controlling chromatographic selectivity by the adjustment of column temperatures in systems of series‐coupled columns is investigated by means of a general model incorporating the effects of temperature and mobile phase compressibility. In a previous article the performance of series‐coupled columns was investigated under conditions of constant overall pressure drop. The present paper, on the other hand, considers systems in which a constant mass flow rate is maintained at all temperatures. The expressions derived for the effective partition coefficient and the retention time are compared with those of the previous paper. The numerical results for two‐column systems exhibit the same major trends as those for constant pressure drop. It is shown that the effective partition coefficient is slightly dependent on the mass flow

摘要:
AbstractTriglycerides are separated according to their molecular weight and their degree of unsaturation on glass capillary columns by use of the on‐column injection technique. The columns employed are silylated SE‐30 columns of 4.5, 8, and 10m length with a film thickness of ca. 0.15 μm. The paper gives several examples of chromatograms of natural and hydrogenated triglycerides as well as of mixtures of pure, known triglycerides before and after interesterifica

摘要:
AbstractThin‐layer gradient elution chromatography is a convenient technique for separation of very complicated mixtures; in some cases the gradient technique can be replaced by continuous development. The two techniques are compared in practice by using them to separate a mixture of dabsyl derivatives of amino acid
