Abstract
CAPILLARY columns have considerable advantages in gas liquid chromatography over the conventional packed columns. However, in order to obtain the advantages from capillary columns, charges of a few micrograms must be used. Such small charges impose severe restrictions on the type of injection system that may be utilized. Several methods for injecting samples have been suggested and the most popular and successful so far has been the gas stream splitter. Although much has been published on the subject of capillary columns, only a small proportion of the work has dealt with the principle of injection, and those papers which have dealt with the quantitative aspects have generally confined their investigations to hydrocarbon mixtures1–3. The stream splitter described here embodies an improved means of vaporizing liquid samples which are introduced. Further, its quantitative characteristics have been examined with samples containing components of widely different chemical class.
