Detectors are another link in the chain of signals that a chromatographic analysis generates. After separation, a detector transduces the chemical signals of eluted analytes to an electrical signal that is then recorded and measured. The identities and amounts of analytes are determined from this information. This month in "GC Connections", John Hinshaw examines the environment, set-up and operating conditions necessary to ensure high gas chromatography detector performance and reliability.

Successful gas chromatography (GC), akin to many other disciplines, requires regular attention to a number of routine procedures. Chromatographers, similar to anyone else, develop habits in their daily work. Some of these help create a successful laboratory environment, while others can be ineffective or worse, can create more problems than they solve. This month, "GC Connections" presents a few of the best and worse laboratory habits.

This month's instalment of "GC Connections" discusses factors that can help determine which type of liquid injection technique is appropriate for specific samples, including having to use existing inlet systems that are on-hand in the laboratory with samples for which they might not be ideally suited.
