    Abstract

    One problem commonly encountered by operators of GC/MS systems is the injection of solvent blanks which are contaminated. The sources of this contamination are many and are often of an undertermined origin. The contaminated blank is an especially troublesome problem when the operator is running a sequence of samples using an autoinjector. The injection of a contaminated blank during a sequence of samples could jeopardize the data collected for any ensuing samples. A simple macro program, described here, will allow the Hewlett-Packard MS ChemStation software to decide if a blank is contaminated. If contamination is present then the software will direct the autoinjector to make the necessary reinjections.
