New Leak Detector
Restek's electronic leak detector lets you pinpoint small gas leaks quickly and accurately before they cause bigger problems. Now, there's no more waiting for a full charge–the new unit can be operated during charging or used up to 12 hours between charges. In addition, it now comes with a flexible charging kit that includes both a universal AC power adaptor and a USB charging cable.

The design of a user-friendly vacuum-jacketed column (VJC) is described for improved LC–MS performance, which does not require a large vacuum chamber with multiple vacuum pumps. Using this configuration, the experimental peak capacities measured for a 2.1 mm × 100 mm column packed with sub-2-μm particles and placed in the VJC-MS probe are doubled with respect to standard LC–MS systems.
