Modes of Operation

Multiple Headspace Extraction with Single Vial Puncture

The use of single puncture mode is not recommended. Agilent recommends
using multiple vial puncture mode.
Multiple Headspace Extraction for Analyte Concentration–
G1289/G1290 only
In this multiple headspace extraction mode, multiple vials are sampled to
concentrate the analytes at the head of the GC column or in a cryo trap at the
GC inlet. A start signal is sent to the GC only after the last vial sampling is
complete. This feature is available only through ChemStation control.
