Sigma precision thread gas chromatography vials online

The vial has a precision thread with numberous threads to force the septa against the vial to seal it to be gas tight. The center hole is designed to be used for SPME as well as standard Headspace analysis, but still offers enough surface for the magnet to transport a completely filled vial.

Screw top vials & caps are recommended for tightest seal & most reproducible headspace results, precision-thread, making them an excellent choice for dependability and ease-of-use. 1] Clear glass Flat bottom vial & PTFE-Silicon septa with Magnetic Screw cap: Part No. 10 ml :-GC10FB07 Pack size: 100 Nos. 20 ml :- GC20FB07.

Our gas chromatography (GC) solutions are designed to be customized so that they can fit any laboratory workflow. From Thermo Scientific iConnect injector and detector modules to our performance-leading Thermo Scientific mass spectrometers, we offer the largest portfolio of GC solutions that enable you to innovate and customize your gas chromatography applications.

Basic Steps of Gas Chromatography Calibration. Switch on the GC instrument and open the carrier gas cylinders or run your gas mixer if you are using one. Adjust pressure and check the carrier gas flow rate, comparing setpoint to observed flows at different rates. Validate gas flow rates against pre-defined acceptance criteria.
