Plastic-body traps such as our SPure Line can provide a lower-cost solution for non-GC applications.

How do you save money with gas filters?

Many gas purifiers include internal indicators, usually for oxygen or water. They change color as they react with the contaminant, which signals depletion of the main adsorbent bed in the purifier.

An easy way to combine the convenience and safety of a permeation-based hydrogen generator with the ultra-high-purity outlet needed for capillary GC is to place a dedicated point-of-use gas purifier downstream of the generator.

High-purity gas is essential for the best GC results. Many point-of-use gas purifiers are available on the market to clean lower grades of gas to carrier grade gas. The point-of-use purifiers come in all kinds of sizes, prices and (claimed) capacities

Adding a chamfer to septa significantly improves performance by guiding the needle to the same location each time, reducing coring. However, without pre-piercing there is still a high risk of contamination by the SPME needle punching a septum core into the liner, presumably on the first piercing...
