Read MoreDavid has over 30 years experience in analytical GC, from gas analysis and trace pesticides to making and testing packed and capillary colums, with former excursions into standard techniques: LC, IR, AA. He’s currently involved with new product development, applying CRS’s strengths in clean inlets and polymers. He has a chemistry degree from Northwestern University and has been with CRS for over 20 years.

Read MoreHow do you save money with gas filters?
Read MoreMany 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.
Read MoreAn 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.
Read MoreHigh-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
Read MoreAdding 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...
