Vacuum-outlet operation of short fused-silica open tubular columns for gas chromatography provides benefits to analysis speed by increasing the optimum velocity while minimizing the loss in resolution. Vacuum-outlet operation of a column with a gas chromatographic detector necessitates that the dete

β¦ Synopsis
The coupling of an aerosol alkali flame ionization detector with high performance liquid chromatography is described. The design of a heated interface allows vaporization of the liquid mobile phase, which prevents extinguishment of a detector flame. Detection limits ranging from (1.10 \mathrm{pg} \mathrm{P} / \mathrm{s}) to (17.0 \mathrm{pg} \mathrm{P} / \mathrm{s}) and (94.8 \mathrm{pg} \mathrm{N} / \mathrm{sec}) to (1890 \mathrm{pg} \mathrm{N} / \mathrm{s}) have been achieved. Selectivity ratios span greater than seven orders of magnitude for the organophosphorus probes and greater than six orders of magnitude for the organonitrogen compounds studied. The effect of detector void volume has also been considered; applications demonstrating detector selectivity are presented. O 1993 Academic Press. Inc.

The performance of electrospray ionization and atmospheric pressure chemical ionisation (APCI) for the analysis of carotenoids was investigated. On our instrument, APCI produced spectra which were readily interpreted, and the positive-ion mode proved applicable to all of the compounds. The separatio
## Abstract An overview of the use of microemulsions as eluents in HPLC is given. The separation mechanisms involved are discussed and the technique is compared to solvent modified micellar chromatography as well as to ordinary reversedβphase HPLC in order to evaluate differences and similarities.
A high performance liquid chromatographic/atmospheric pressure chemical ionization mass spectrometric (APCI-MS) method has been developed for the determination of 10 pesticides. Initial comparison was made between the two atmospheric pressure ionization techniques, APCI and electrospray. Optimum sep
