wide opening flat bottom headspace gas chromatography with closures manufacturer

Chrom Tech carries a complete offering of GC vials, otherwise known as crimp style vials, for use with most gas chromatography autosamplers. Most GC laboratories use crimp top vials for GC applications due to their ability to seal well and accommodate highly volatile compounds.

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.

Components in a gas chromatograph include a sample injector, flow controller, GC column, column oven, a detector, and a computer for data acquisition and analysis. A combination of electronic sensors and pumps maintain either a constant or variable mobile phase flow rate from 0.001 to 100 mL per minute. GC instruments typically have a maximum

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 GC vials Product Features: Beveled neck headspace vials are avaliable in borosilicate Type I clear & Amber Glass 10 ml & 20 ml volume capacities. For proper fittining to all standard instruments we have both flat bottom & round bottom vials. Headspace vials are available in both crimp cap & screw cap types.

The United States Pharmacopeia (USP) method 467 is a common headspace application. It detects and measures solvents from the pharmaceutical manufacturing process that may be present in over-the-counter and prescription drugs to ensure they meet regulatory guidelines and are safe for consumers.

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. How does headspace sampling work?

Jan 1, 2021 · Headspace extraction is one of the most straightforward and common sample preparation techniques for gas chromatography. In general, volatile analytes are extracted from liquid or solid samples by placing them in a sealed vial, bringing the system to equilibrium, and collecting a sample of the vapor.

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.
