Analytical Industries PI2-UHP oxygen analyser

Click2Contact

Michell Instruments is now offering users in the semiconductor and gas manufacturing industries a trace oxygen analyser for ensuring the quality of ultrahigh-purity gases.

Analytical Industries’ PI2-UHP oxygen analyser has a low detection limit of 0–50 PPB low range with LDL <0.1 PPB. It is designed to measure trace-level oxygen contamination in ultrahigh-purity inert gases in the semiconductor industries.

The Pico-Ion electrochemical sensor is maintenance-free and routine calibrations are quick and simple due to the built-in auto-calibration and sample handling system. There is no need to add electrolyte. The analyser has an integral temperature-controlled heated enclosure and stainless steel all-welded sample system. Fully automated auto-zero and auto-cal, as well as an integral data logger, are all features of the analyser.

To ensure the zero gas is completely free of O₂, an oxygen scrubber is included as part of the integrated sampling system. To protect the sensor, a sample bypass is provided to isolate the sensor from high oxygen levels during start-up, sample line switching and maintenance.
