Title: Utility programs used for EPA Contract Laboratory Program computations

Abstract

Four computer programs were developed to manipulate GC/MS data and expedite both sample turnaround time and data package preparation for presentation of data following the EPA Contract Laboratory Program requirements. One program rapidly determines if the GC/MS daily standard has met QC criteria and therefore allows more samples to be analyzed within the 12-hour time limit. Another extracts total ion current for quantitation of tentatively identified compounds. The limit of detection is obtained on an as needed basis by the third, and the fourth provides a list of the names of target compounds, internal standards, and surrogate standards from the daily standard with their retention times in increasing order of elution. This paper describes the format, data entry approach, and procedures to set up and run these programs.
