Retention time locking procedure for comprehensive two-dimensional gas chromatography

, 2011
In gas chromatography (GC) reproducible retention times are in many cases highly favorable or in some cases even required. In one-dimensional GC, retention time shifts can be eliminated or minimized using a procedure called retention time locking (RTL ...
