Column Packings and Efficiency in High Pressure Liquid Chromatography,fect of particle size on efficiency at high carrier velocity. It has now become an accepted principle that the way to achieve high speed in liquid chromatography is to use small particle diameter packing (1, 2, 3). Since the principle was first reported by such early workers as Huber (4), Snyder (5)

Factors Affecting the Reproducibility in Pyrolysis Gas Chromatography (PGC),and PGC’s utility. Normalized pyrograms obtained under standard conditions could be compiled and used as reference spectra. The accumulation of compiled reference data will permit the deduction of modes of thermal fragmentation which, in turn, could be used for interpretation of new pyrograms not li
