Our line of GC/GC-MS supplies includes PID lamps, electron multipliers and filaments, and standards. These parts are compatible with many brands in the industry including Aijiren, PerkinElmer, Varian, and Thermo Scientific. Standards for common EPA methods and for unique and specialized testing are available.

All crimping tools, even the high speed pharmaceutical crimping machines, work by forming the cap around the vial lip in a process that uses position to determine the end of the forming operation. The cap is crimped with a geometry defined by the crimping tool. The crimping tool or machine itself has no way to assess the tightness of the cap.

These headspace vials are manufactured from Type I borosilicate glass, which meets all USP, JP, and EP Pharmacopeia requirements.Designed to use separating organic and inorganic compounds for analysis, chromatography vials come in different finishes to guarantee chemical compatibility. Autosampler compatible closures come in different colors, sizes, and septa materials. Offered with a write-on

Aijiren designed the 20ml crimp top headspace vials in order to be more Accurately use with your instrument. 20ml crimp top headspace vial has a very good seal and can be used for volatile samples, but it needs to be used with 20mm Hand Crimper to seal the vials, and when opening the lid, it needs to be sealed with 20mm Hand Decrimper.

20 mm crimp caps Two sizes: 23 x 75 and 23 x 46 mm Round bottom glass headspace vials feature a 20 mm beveled crimp top that creates a much tighter seal than you get with a flat crimp surface. Vials are designed for use with Perkin-Elmer, Tekmar and Varian.

Designed for targeted and non-targeted analysis, it provides exceptional characterization of samples and is ideal for chemical, petroleum, food and personal care product applications. With our easy-to-operate (and carry) Torion ® T-9 portable GC MS, you can virtually bring your lab to the sample. Although it was built for portability and speed

Graphite or Vespel/graphite ferrules are used to seal the column to the injector and detector in capillary gas chromatography. Both ferrule types have advantages and disadvantages. Graphite ferrules are the easiest to use, and they are leak-free, universal for most systems, and preferred by most beginning capillary chromatographers.

Headspace Vials. Headspace vials and closures must form a tight seal for accurate analysis with reproducible results. Available in clear or amber Type I borosilicate glass with crimp or screw thread finishes. The vials are used to heat the sample until the concentration of the liquid and gas phases are in equilibrium.
