Method Development
Multiple extractions
Two typical uses for multiple extraction mode are kinetic
studies and calibration.
Note that the vial is punctured only once during the
extractions.
Concentrated extractions
This mode can be useful for trace analysis, where the sample
can accumulate in the GC inlet or other trap before being
swept onto the GC column. This mode requires the use of a
multimode inlet or other type of trap.
