Analytical Industries Oxygen Analyzers for Ultra-High Purity Gases

Analytical Industries Oxygen Analyzers for Ultra-High Purity Gases

Based on the stable and long-life Pico-Ion oxygen sensors, the PI2 range of trace oxygen analyzers provides accurate and stable measurements of oxygen down to low parts per trillion. Low cost of ownership through minimal maintenance of this high-performance oxygen analyzer make measurement of oxygen down to ppt level easy and affordable for customers with limited budgets.

Highlights

  • Measuring trace O2 in ultra-pure Ar, H2 , He and N2
  • LDL to less than 100 ppt
  • Low cost of ownership
  • User friendly and easy to operate and maintain
  • Fast recovery from process upsets
  • Integrated bypass sample system as standard
  • Optional auto calibration system with true zero feature via O2 scrubber

Second generation, nomaintenance Pico-Ion sensor technology

A high-performance, low ppb oxygen sensor with stable output requiring no maintenance or frequent electrolyte additions. The innovative design of the gas chamber maximizes the rate of oxygen reaction while the refined proprietary sensor design provides a high signal output per unit area to enhance sensitivity as well as a significantly higher output. Further advantages are:

  • Lower detectable limit (LDL) of less than 100ppt
  • High signal to noise ratio
  • Excellent stability
  • Response time of less than 15 seconds
  • Minimizes the temperature dependence
  • Fast recovery from higher oxygen levels during process upset conditions
  • Approximately 12 months of continuous use

Standard Full Featured Automated Sample System

The PI2-UHP analyzers have a full featured ultra-clean sampling system designed for the measuring < 100 PPT oxygen :

  • 316 stainless wetted parts including electro-polished tubing, Face Seal fittings or orbital welded connections
  • Integral pressure regulator and flow control
  • Pneumatic diaphragm valves that operate :
    - Sample and span gas inlets
    - Integral bypass system that isolates the sensor from high oxygen levels and
    - An oxygen scrubber system for generating consistent zero gas
  • Temperature control of the sample system limits drift during day-and-night cycles where ambient temperatures fluctuations were typically ±10F°.
