A retention index scheme for use with sulfur specific detectors

Kevin L. Goodner, Carlos A. Margaria, Elizabeth A. Baldwin


Retention indices are very important for compound identification when using gas chromatography. Retention indices are important because they remain static under different conditions and instruments while retention times vary dramatically. Generally, a retention index is generated using a series of straight chain alkanes and is referred to as a Kovats' Index after the originator E. Kovats. However, alkanes will not produce a response when using a sulfur specific detector. For this reason, a sulfur specific retention index has been developed and will be presented along with the comparison to a standard Kovats' retention index.
