Method for Rapid Transfer of GLC Fractions into Infrared Cavity Cells

Volume 21, Number 1 (Feb. 1967) Page 31-32

Kendall, R.F.


Combining gas-liquid chromatography (GLC) and infrared spectrophotometry is an established analytical practice. Special trapping procedures are required, however, for the collection and successful infrared analysis of microliter samples obtained from GLC instruments. Procedures designed for the collection of volatile GLC effluents include: (1) Trapping in powdered potassium bromide, followed by pelleting; (2) trapping in thermoelectrically cooled cells, for use with multiple reflection attachments; (3) trapping in capillary tubes containing solvent; and (4) trapping through a special fraction collector into ultramicrocavity cells, which are used with beam-condensing equipment.
