Autosampler for Gas Chromatography, 22-Position Tray
Automatic liquid sampler that injects from a 22-position tray into a gas chromatograph, for unattended sequences and repeatable injection volumes.
Typical applications
- Unattended overnight GC sequences
- Routine QC batches
- Solvent wash and blank sequences
- Bar-coded sample tracking

Worth knowing before you order
The tray is 22 positions in total and the catalogue splits it as 19 sample vials, two solvent vials and one waste vial - the usable sample count is 19, not 22. Syringes are sized against the injection volume (0.1 µl needs a 1 µl syringe, 250 µl needs a 500 µl syringe) and are consumables, so confirm which syringe and which vials and septa are in the quotation. Control is through the gas chromatograph software over one of several I/O modes, so the connection has to be checked against the specific chromatograph before ordering rather than assumed.Specification
