"Ion Mobility Spectrometry As Flow Injection Detector And Continuous-flow Monitor For Aniline In Hexane And Water"
Talanta 1992 Volume 39, Issue 5 Pages 459-467
Gary A. Eiceman*, Lizbeth Garcia-Gonzalez, Yuan-Feng Wang and Bobby PittmanG. Edward Burroughs,

Abstract: Ion mobility spectrometry (IMS) was used as a flow injection detector to quant. examine the ionization chemical of aniline in hexane. A 5 µL sample was vaporized at 15-90-s intervals in a flowing air stream and analyzed with an IMS equipped with acetone reactant ion chemistry, ambient temperature drift tube and membrane-based inlet. Precision was 3-11% relative standard deviation for 1-100 ppm aniline in hexane with 90-s injection intervals and detection limits were ~0.5 ppm with 5 µL injections. Matrix effects with amine and organic solvent mixtures were observed and corrected for low and medium proton affinity interferences with standard addition methods. Pronounced fouling of the IMS occurred when a continuous water flow was introduced for aqueous flow injection IMS. Continuous water monitoring without degraded IMS performance was possible by sampling air flow-through a Silastic tube immersed in an aqueous sample.

"FTIR Microscopy As Novel Detection System In Micro Flow Injection Analysis"
Anal. Methods Instrum. 1995 Volume 2, Issue 1 Pages 52-54
Kellner, Robert; Lendl, Bernhard

Abstract: A Bruker 113v FTIR spectrometer was coupled with a Bruker IR microscope equipped with a HgCdTe detector. A flow-through cell was developed for this system comprising three parts; the central part of which was constructed of PVC with an inner volume of 1.6 µL and an optical pathlength of 500 µm. The windows consisted of two Si plates (diameter 5.5 mm, thickness 0.75 mm). As the IR beam is focused by the FTIR microscope down to 80 µm it was possible to probe volumes of 10 nl. IBMK was determined in hexane in the ppm range as a model substance. Possible future applications of the system as a µtotal analysis system are discussed.
