Best Practice for Identifying Leaks in GC and GC/MS Systems

Version 1

    Maintaining a leak-free GC or GC/MS system is critical for obtaining optimal system performance with reliable, reproducible, and accurate results. The symptoms typically observed from leaks are presented, along with a discussion of key areas of focus to identify leaks and how to correct them. Key facets discussed in obtaining optimal system performance include the use of high quality carrier gas, selection of the proper ferrule, proper just-tight-enough (JTE) ferrule installation, checking for leaks in GC and GC/MS systems, and an innovative self-tightening column nut for maintaining leak-free connections.
