✦ Synopsis

A systematic study of the utility of stainless-steel wire nets (SSWN) as a substrate for infrared sampling is described. The nets can be used with polar solvents including water, as well as non-polar solvents, without harming the surface. The use of the SSWN simplifies interfacing between a reversed-phase liquid chromatograph (l.c.) and a Fourier-transform infrared spectrometer. It is used as a l.c. detector cell by collecting the effluent from l.c. on the cell itself. The technique is tested extensively with carbaryl as sample and is applied successfully to the detection of a pharmaceutical mixture (phenacetin, caffeine and aspirin) separated by reversed-phase l.c. with a (3:2, v/v) methanol/water mobile phase.
