There are many kinds of fittings on the market for gas filters, including standard compression fittings, quick connect fittings, and push to connect fittings- to name a few. We are going to take a look at the different kinds of fittings and their applications

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

Indicating purifiers are popular for obvious reasons – you like to know that your filter is really working. It is possible to get moisture indicators and oxygen indicators that turn color when exposed to the target gas at the 1 ppm level?

Minute leaks can remain during purifier manufacturing...

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. So – in the absence of a high-priced residual force tester – how do we determine the tightness of the cap?

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...

CRS provides a wide range of ferrules made from Vespel®, Vespel/Graphite, Graphite and PTFE. Ferrule sizes refer to the size of the fittings into which they fit; they arenot the diameter of the ferrule. For example, 1/16" ferrules are 1/8" diameter and fit in 1/16" fittings.

When searching for an indicating gas purifier, you will find there are many filters containing a variety of moisture indicators on the market. It is important that you pick the right indicator for your specific application to get optimal performance.
