GC Headspace Sampler
Heats a sealed vial containing the sample so volatile compounds move into the gas above it, then injects a portion of that gas into the GC. The standard way to test residual solvents without putting the sample matrix into the GC.

Headspace calibration procedures
Headspace has no instrument calibration of its own in most labs. Its performance is controlled through qualification (below) and the system suitability or acceptance checks of each test that uses it.
Instrument qualification (DQ · IQ · OQ · PQ)
- 01
DQ — Design qualification
States the needs: vial capacity, oven range, loop or pressure-balanced sampling, shaking, compatibility with the GC and CDS control.
- 02
IQ — Installation qualification
Confirms correct installation: serial numbers, gas connections, transfer line fitted to the GC inlet, firmware and documentation.
- 03
OQ — Operational qualification
Checks vial oven temperature accuracy, pneumatic leak test, and area precision and carry-over with a volatile test standard.
- 04
PQ — Performance qualification
Shows ongoing fitness for use, typically by the residual solvents system suitability test run with each sequence.
Keep every Headspace in control: usage logs, calibration and maintenance schedules, and automatic blocking of overdue instruments.
