The helium leak detector is a portable, highly sensitive instrument designed to detect helium carrier gas leaks in thermal desorption and GC systems. Gas leaks are indicated with both an indicator lamp display and an audible alarm. The long, flexible probe makes it convenient to detect small and hard-to-reach gas leaks. Using the detector for gases other than helium is easily achieved by changing the polarity setting. The det…

Accurate and repeatable gas flow measurement. Accurate and repeatable gas flow measurement is fundamental to obtaining good results from your thermal desorption-gas chromatograph. The traditional bubble flowmeter, relying as it does on the reaction time of the operator, is a potential source of error.The digital flowmeter eliminates this source of error and makes gas flow easement easier and more accurate. The flowmeter allow…

Reversible Flip Seal—Same Cost, Twice the Lifetime New reversible Flip Seal inlet seals from Restek last twice as long as other inlet seals. Simply use—flip—then use again. The reversible design doubles the number of analyses you get per seal. •Same easy sealing as Dual Vespel® Ring Inlet Seals—no extra washer needed. •Lower leak rate than OEM metal seals. •Maximum transfer of analytes to column, due to highly inert gold or Si…

• Optimized deactivation produces maximum response when analyzing trace levels of acetylene, methyl acetylene, and propadiene. • Stable response factors make this column ideal for process-type applications where recalibration must be minimized. • High loadability reduces peak tailing and improves separations. • Extended temperature range up to 250 °C for fast elution of high molecular weight (HMW) hydrocarbons and accelerated…

A revolutionary new version of Restek’s popular EZGC™ application is now live — it’s easier to use and it’s absolutely free. Just enter your compounds, and this cutting-edge system will recommend not only a GC column, but also the conditions to reliably separate your target analytes. It will even show you a modeled chromatogram! On a PC or Mac, desktop or tablet, the EZGC™ web app can go anywhere and will quickly become your g…
