Helium-to-neon modification for a DuPont 120SSA or 24-120 leak detector
Description:
When helium leak detecting is hindered by a system or atmosphere saturated with helium, leak checking can be continued by modifying the DuPont 120SSA/24-120 Mass Spectrometer Leak Detector to detect neon. Although DuPont markets a three gas leak detector (helium, neon and argon), the DuPont 120SSA/24-120 is convertible to neon by simply changing the magnet and retuning for neon peak. The sensitivity is 2 x 10/sup -9/ Atm/cc/sec/division neon. If an increase in sensitivity is desired, throttle d…
