LD239 Helium Leak Detector
Gas leaks can cause detector noise and baseline instability, shorten column life and waste expensive carrier gas. Liquid leak detectors, although inexpensive, can contaminate your GC system. GL Sciences' LD239 leak detector, introduced in 2012 (and replacing it's predecessor, the LD229) is an easy way to quickly identify leaks in your system - check your valves, fittings, and traps for leaks after every maintenance, and after thermal cycling as these can loosen some types of fittings.
LD239 provides the most sensitive He leak detection available in an inexpensive, compact, easily chared (via USB), and easy to use configuration.
