Introduction to Headspace and to the G1888 Network Headspace Sampler
The G1888 Network Headspace Sampler
The G1888 Network Headspace Sampler provides an automated
method to run up to 70 samples consecutively without operator
attention. The sampler’s microprocessor optimizes the time
spent for each run according to the values programmed in by
the operator. Up to four different methods can be stored and
used to analyze a series of samples.
The Headspace Sampler can also do multiple headspace
extraction (MHE) using multiple septum punctures, with up to
100 extractions per sample. MHE can also be used to automate
optimization routines.
A second method of MHE named the CONC mode is available.
CONC mode allows sample concentration at the head of the
column for trace analysis.
See Figure 1 and Figure 2 for a visual overview of the
Headspace Sampler.
