Residual Gas Analyzer

Better than 1 amu resolution 6 orders of magnitude dynamic range in a single scan 5 x 10 -14 Torr detection limit RGA Windows software RS-232 & Ethernet interfaces 100, 200 and 300 amu systems RGA Series Residual Gas Analyzers The 100, 200 and 300 amu residual gas analyzers from SRS offer exceptional performance and value. These RGA's provide detailed gas analysis of vacuum systems at about half the price of competitive models. Each RGA system comes complete with a quadrupole probe, electronics control unit (ECU), and a real-time Windows software package that is used for data acquisition and analysis, as well as probe control. ... click for RGA Tech Support RGA Software Download RGA Windows (legacy software) RGA Python Driver RGA Basics RGA Ethernet Adapter Manual Max Insertion Nipple Replacement Ionizer Kit RGA Work Stand Drawing Vacuum Diagnosis RGA Ion Counting Output Pressure Conversion Table RGA Volatility Statement Analog Scan File Format RGA120 Series Gas Analyzers PPR Gas Analyzer CIS Gas Analyzer PPM100 RGA Monitor RGA Software Download RGA Windows (legacy software) RGA Python Driver RGA Basics Ethernet Adapt.

The simple design has a small number of parts which minimizes outgassing and reduces the chances of introducing impurities into your vacuum system. The probe assembly is rugged and mounts onto a standard 2 ¾ inch CF flange. It is covered with a stainless steel tube with the exception of the ionizer which requires just 2 ½ inches of clearance in your vacuum system—about that of a standard ion gauge. The probe is designed using self-aligning parts so it can easily be reassembled after cleaning. Compact Electronics Control Unit The densely packed ECU contains all the necessary electronics for controlling the RGA head. It is powered by either an external +24 VDC (2.5 A) power supply or an optional, built-in power module which plugs into an AC outlet. LED indicators provide instant feedback on the status of the electron multiplier, filament, electronics system and the probe. The ECU can easily be removed from the probe for high temperature bakeouts. Unique Filament Design A long-life, dual thoriated-iridium (ThO 2 /Ir) filament is used for electron emission. Dual ThO 2 /Ir filaments last much longer than single filaments, maximizing the time between filament replacement. Unlike other designs, SRS filaments can be replaced by the user in a matter of minutes. Dual Thoriated-Iridium Filament X Dual Thoriated-Iridium Filament RGA series Dual Thoriated-Iridium Filament A Faraday cup detector is standard with SRS RGA systems which allows partial pressure measurements from 10 -5 to 5 × 10 -11 Torr . For increased sensitivity and faster scan rates, an optional electron multiplier is offered that detects partial pressures down to 5 × 10 -14 Torr . This state-of-the-art macro multi-channel continuous-dynode electron multiplier (CDEM) offers increased longevity and stability and can also be replaced by the user—a first for RGAs! The O100HJRW Heater Jacket comes with a Watlow EHG SL10 Process Controller that provides a preprogrammed temperature of 210 °C (±3 °C). The Heater Jacket is made using PTFE (Teflon) construction, suitable for clean room applications due to its low out-gassing and particle free operation. The O100HJRW is offered in 120 VAC and 220 VAC versions, and is shipped with a country of destination power cord. Heater Jacket X RGA Heater Jacket RGA series All RGAs have a built-in degassing feature. Using electron impact desorption, the ion source is thoroughly cleaned, greatly reducing the ionizer's contribution to background noise. A firmware driven filament protection feature constantly monitors (675 Hz) for over pressure. If over pressure is detected, the filament is immediately shut off, preserving its life. A unique temperature-compensated, logarithmic electrometer detects ion current from 10 -7 to 10 -15 Amps in a single scan with better than 2 % precision. This huge dynamic range means you can make measurements of small and large gas concentrations simultaneously. Complete Programmability Communication with computers is made via the RS-232 interface. Analog and histogram (bar) scans, leak detection and probe parameters are all controlled and monitored through a high-level command set. This allows easy integration into existing programs.
