The Agilent gas leak detector provides you with an easy way to quickly identify gas leaks in your GC system. Gas leaks can cause detector noise and baseline instability, shorten column life, and waste expensive carrier gas. The Agilent GC leak detector is an electronic leak detector, which means that there is no danger of contaminating your system as with less expensive liquid-based leak detectors. Always check your valves, fittings, and traps for leaks after every maintenance, and after thermal cycling as these can loosen some types of fittings.
