This listing is for the sale of a replacement probe for the model AV100-EM, 1-100 AMU Ideal Vacuum AnalyzaVAC Residual Gas Analyzer with an electron multiplier.
It includes the probe with mass filter, ionizer assembly, dual thoria coated iridium filaments, and electron multiplier.
Note that the AnalyzaVac RGA cannot be field upgraded with a probe of a different AMU range nor can an electron multiplier be added to an RGA without one. If you would like to upgrade the AMU range or add an electron multiplier, the RGA must be sent to Ideal Vacuum for a factory electronics upgrade along with the new probe or multiplier. Please contact your sales representative for options.
The optimal total operational pressure of the RGA is 2×10-7 Torr for most gases. Operation at higher pressures for extended lengths of time will results in premature aging of the probe, loss of gain, spectral drift, and fillament and ionizer burnout. The RGA can be used at the following pressure regions for the corresponding lengths of time:
10-4 Torr, several hours
10-5 Torr, several days
10-6 Torr, several months
10-7 Torr, several years
10-8 Torr, indefinitely
Organic vapors should be kept at a 2x lower pressure than atmospheric gases to prevent soot contamination of the fillament and ionizer. Silicone vapors should be kept at pressures at least 10x lower than atmospheric gases to prevent glass buildup on the fillament and ionizer. Corrosive vapors are also more damaging to the RGA than normal gases. By properly managing pressure, the RGA can be used to measure these gases without incurring costly repairs.

Please read carefully before ordering:
* The AnalyzaVAC probe is a delicate instrument. Inappropriate use, mishandling of the probe, or operating at elevated pressures for extended amounts of time can contaminate and damage it. Therefore, the probe does not carry a warranty after removal from its original packaging.
