Michell Instruments introduces a new class-leading range of trace oxygen
analysers for use in semiconductor and gas manufacturing industries to ensure the
quality of ultra-high purity gases.
Analytical Industries’ PI2-UHP oxygen analyser from Michell Instruments
is designed to measure trace-level oxygen contamination in high-purity gases.
Featuring a low detection limit of 0-50 PPB low range with LDL <0.1 PPB for
checking purity of ultra-high purity inert gases in the semiconductor
industries, the new oxygen analyser combines cost-effectiveness with excellent
Key features of the PI2-UHP oxygen analysers include a maintenance-free Pico-Ion
electrochemical sensor; quick and simple routine calibrations thanks to the
built-in auto-calibration and sample handling system; integral temperature
controlled heated enclosure; stainless steel all welded sample system; and fully
automated auto-zero and auto-cal, integral data logger.
To ensure the zero gas is completely free of oxygen, an oxygen scrubber
is included as part of the integrated sampling system. A sample bypass is also provided
to protect the sensor by isolating it from high oxygen levels during start-up,
sample line switching and maintenance.
