Select kits with SureStop™ vials and/or AVCS™ screw caps for effective seals, consistent data, and increased sample throughput. Certified high-performance kits for use with mass spectrometry research applications – with an additional level of security. Our MSCERT+ kits are tested by both LC-MS and GC-MS to ensure that there are no
A specially moulded seal with a PTFE insert. Sealing surface of Butyl and PTFE affects a more positive seal than non-PTFE-faced septa. Ideal choice for temperatures below 125°C. Good sealing characteristics, excellent resistance to most solvents with reduced coring and high puncture tolerance.
heated to temperatures over 200 °C for high-temperature extraction, they were sealed with heat-resistant headspace vial septa that minimize bleeding at high temperatures (Shimadzu, P/N: 225-40950-91). The analytical conditions are indicated in Table 4. For high-temperature extraction, n-alkane was also analyzed to
Static headspace (HS) coupled with gas chromatography (GC) has been widely used for collecting quantitative and qualitative information on the volatile components that are present in complex sample matrices. • Volatile components released into vapor phase by heating the sample.
were equilibrated at 300°C for 30 min. By using High Performance septa, the vial blank chromatogram clearly shows chromatograms with minimal septa contamination from low to high vial initial pressure. GC/MS Instrument conditions • Aijiren A GC/ HS samper/ MSD • S/SL inlet under split mode @ 250°C with 10:1 of split ratio •
Aug 5, 2022 · General Purpose Blue Septa are suitable for most GC applications, they have a service life of up to 150 injections, and the maximum working temperature is 250 °C. They are produced in diameters
Septa are made from different materials. See below for definitions and uses of different types of septa materials. Rubber septa. Used primarily for routine analysis in gas chromatography. Offers moderate ability to reseal and good chemical inertness. Not recommended for multiple injections or holding samples for further analysis.

Hamilton. High Temperature Septa is made of preconditioned PTFE/silicone rubber and is 3.175 mm (0.125 in.) thick. The average life of these septa is up to 100 injections with a 26s gauge needle. The maximum operating temperature is 212° C. Preconditioned PTFE/silicone rubber septa, 3.175 mm. Compare this item.
Precision molded GC Injection Port septa are manufactured from 100% Pure Premium Silicone Rubber. Our GC Injection Port septa deliver the ultimate in low bleed properties and longevity. Our unique formulation and conditioning process, as well as our ability to provide custom packaging, is what separates our GC Septa from the rest.
PTFE/ Synthetic Red Rubber septa are an economical choice for general GC and HPLC applications. Used primarily for routine analysis in gas chromatography with FID, TCD and FPD detectors or HPLC with UV/Vis or RI detectors, PTFE/Synthetic Red Rubber septa offer good resealability and excellent chemical inertness before puncture.
Molded Septa are manufactured from high quality, low bleed material that uses the same exclusive LB-2 rubber formulation chromatographers are accustomed to using. Design. With Injection Hole. Type. Septa. For Use With (Equipment) Low Bleed GC-MS Columns. Temperature (Metric) Max. 350°C.
There are three types of Aijiren premium septa from which to choose to suit all GC application types: the Bleed and Temperature Optimized (BTO), the Advanced Green, and the Long Life septa.
