A possibility is demonstrated of the use of the flame ionization detector (FID) and the alkali metal flame ionization detector (AFID) in capillary liquid chromatography. The minimum detectable mass flow rates for the FID and the AFID were ≈10-12 and ≈10-13 g s-1, respectively. The detection time constant is about 1 s allows for operation with columns of inner diameters of 10-60 μm and lengths above 1 m. The suggested design of the detector is described. The burner allows the total effluent from the column to enter the detector. The temperature of the end of the capillary column in the burner is controllable.

Abstract Phenothiazine, promethazine.HCl, chlorpromazine. HCl, promazine.HCl, and levomepromazine. HCl were chromatographed satisfactorily on a column containing 5% Apiezon L coated on Anakrom ABS, 100/110 mesh, using a hydrogen-flame ionization detector. This gas chromatographic technique is rapid and more specific than existing official methods. The use of an internal standard to improve precision will be investigated.

The design and characterization of a flame ionization detector (FID) that is compatible with the high flow rates of packed-column supercritical fluid chromatography (pSFC) is presented. The modified FID uses a large quartz burner (4.0 mm i.d.) in place of the conventional burner (0.4 mm i.d.) and operates a stable flame in the presence of gas flows tested up to nearly 3000 mL/min. This modification allows the full flow of effluent from a pSFC column (i.e., splitless mode) to be directed into the FID. Results demonstrate that the modified FID yields response that is within a factor of 3 to that of a commercial FID. The attributes of the modified detector indicate that this approach could be a reliable and relatively simple means of achieving a splitless pSFC-FID system.Key words: supercritical fluid chromatography, packed column, splitless, flame ionization detector.
