## Abstract A splitless injection method using makeโup flow was developed for SFC. Dilution of sample solvent with carbon dioxide mobile phase was very effective for focusing the solutes onto the column. Injection of a 4.5โฮผl sample volume on a 100โฮผm i.d. capillary column became possible.
Reduction of the column diameter has proved to be a highly efficient tool to increase the speed of analysis. Unfortunately, the requirementsfor instrumental design with respect tosample input band width, low dead volume interfacing, and time constants of detection and registration systems are the mo
The introduction of selected fractions from a liquid chromatograph into a gas chromatograph has been described; however, analyses were performed by off-line experiments requiring collection and reinjection of the separate fractions or by on-line procedures where disadvantageously, only a fraction of
