| Abstract |
|
In this experiment designed for the undergraduate instrumental analysis laboratory, a pulsed discharge photoionization detector (PDPID) is used to efficiently differentiate between and qualitatively identify 12 compounds in a sample mixture. This is accomplished using benzene as an internal standard and by correlating the relative responses of the 11 organic compounds in a He, Ar, and Kr PDPID with their relative retention times. This method is designed to be safe, relatively inexpensive, virtually nondestructive, and highly sensitive.
