Check Valves for Leaks

Valve leakage due to sample particles or oxidized mercury deposits on valve seats can cause difficulty in attaining adequate vacuum conditions. To test for leakage:

  1. Open valves 1, 2, 3, and 8.
  2. If the pressure does not reach 100 µm in less than five minutes, the system has a leak. If this occurs, clean the valves. See Clean Valves .
