high quality flat bottom headspace gas chromatography with closures manufacturer

Thermo Scientific Advanced Vial Closure System (AVCS) caps are polypropylene caps that are compatible with all 9 mm short thread screw vials, although we recommend that they are used with our Thermo Scientific SureStop vials to get maximum benefit of the two technologies.

Headspace Analysis works on the principle of Tunable diode laser absorption spectroscopy (TDLAS), a non-destructive method able to measure the concentration of a certain gas in closed container even at very low detection limits, with a sufficient headspace size to pass through with a laser beam.

Mar 22, 2020 · The sizes for 12x32mm vials outer dimensions are standard between manufacturers but the length of the neck and screw thread of the 9mm (N9) vial may vary, because 9mm short thread is not industry standardized. 3. Chromatography Sample Compatibility The sample solvent compatibility should be considered when choosing vials and septas.

Headspace GC is a sample preparation method for determining volatile compounds in solid and liquid samples. The technique has existed since the late 1950s [12] and is still actively used. With this technique, only the gas phase above the sample is introduced into the GC column.

Step 1 GC Autosamplers Step 2 GC Injectors Step 3 GC Detectors Step 4 GC Columns Step 5 GC-MS Step 6 GC Software GC Autosamplers

I want to share some of the most common issues that we see with peak shapes in Gas Chromatography in the hope that if you spot some of these in your own work, you may be able to intercept problems and deal with them more effectively. Example 1 – Peak Tailing. Figure 1: Chromatograms showing worsening peak tailing effects.

Headspace is used to analyze volatile compounds in liquid and solid samples that cannot be injected directly into a gas chromatograph (GC). Examples would be creams and lotions, blood, soil, electronic components, and polymers. Headspace sampling can accommodate virtually any matrix.
