Developing Better GC Methods — A Blueprint
December 1st 2014To obtain sensitive, robust, and reproducible gas chromatography (GC) methods, each stage of the chromatographic process needs to be carefully considered and optimized. It is also important to record and report as much detail within the method specification so that the method can be reproduced between operators, instruments, and laboratories. Table I represents a "blueprint" method specification with all of the information that is necessary to faithfully specify and reproduce a split–splitless GC method.
