Abstract

Supercritical fluid chromatography coupled with supersonic jet spectroscopy has been shown to be an effective analytical technique in the analysis of complex samples. This highly selective technique derives its power from the combination of a powerful separation technique and an discriminating spectroscopic identification technique. Using them in tandem an investigator can analyze complex mixtures for specific compounds. Unfortunately, till now the compounds that could be analyzed were limited in their size, by the requirements necessary to couple the two methods together. The work reported here is the first step to opening up this analysis to larger molecular weight samples.
