max pressure for RGA use:
Quoth RGA the manual
"Quadrupole analysers cannot be operated at pressures higher than 5 x 10-4 Torr and in the case of dual detector analysers (faraday and electron multiplier detectors), the multiplier should not be used at pressures above 7.6 x 10-6 Torr." we need multiplier data to qualify, so i simplified that down to:"max pressure for RGA use: 7.6E-6 Torr"
