20mm crimp vial

Unveiling the key role of crimp caps in chromatography - from preserving samples to ensuring reliable results. Learn why they matter.

Headspace analysis is particularly sensitive to the quality of the sealing system used to contain the sample. The high pressures and high temperatures in use require high-performance and reproducible seals. Newer analyzers coming on the market continue to push the envelope on these requirements [See, the Shimadzu HS-20, the Agilent 7697A (See Configuration with Tray), and the Thermo Scientific TriPlus for examples of headspace samplers with oven temperatures up to 300°C]. At higher temperatures, high-quality seals are a condition for reproducible analysis free of siloxane contamination.
