DUAL-CHANNEL GAS DETECTOR FOR STERILE ENVIRONMENTS

ATi UK’s IsoMon dual-channel gas detection system has revolutionised the way sterilisation cycles are processed, monitoring the complete decontamination process from start to finish and measuring gas levels of both high and low concentration.

This unique system, part of ATi UK’s PharmaSafe range, has been primarily developed to address the sterilisation needs of the pharmaceutical, biological, medical device manufacturing, defence, industrial, healthcare and food packaging industries, but can also be deployed to reduce the occurrence of hospital-acquired infections and even the decontamination of aircraft cabins.

The two-channel detector measures both high and low gas concentrations in sterilised environments, proving that peroxide levels have reached a high enough level for sanitisation AND that they are safe following sterilisation.

The IsoMon was developed by ATi UK to meet the market need for simultaneous high-level concentration measurements and low-level verification. Hydrogen peroxide is extensively used in the medical and pharmaceutical industries to sanitise working environments. It is often necessary to make measurements at a high-range to ensure that sanitisation has taken place and then to have to take a measurement at a much lower range. This ensures that the area is safe to re-enter (room monitoring) and that product can be introduced (isolator monitoring).


These measurements are not possible with a single sensor, due to the high-range H2O2 concentration saturating the low-range sensor. In addition, the high-range sensor does not have good enough resolution at the low-range.  It was with this is in mind that ATi developed the dual sensor IsoMon, with a fully automated sample-switching arrangement that uses the most appropriate sensor for the measurement. This protects the low sensor and gives the most appropriate measuring range.

The detector can measure samples to a maximum 2000ppm and minimum 0ppm within one single unit, designed to ensure that environments have reached sterile levels using H2O2 and that the H2O2 subsequently drops to safe ambient levels post-sterilisation.

Tristen Preger, ATi UK Director of OEM Sales and New Business, said: “IsoMon is a first-of-its-kind gas detector that allows both high and low value measurements of Hydrogen Peroxide levels, providing users with reliable validation data regarding the sterilisation of aseptic environments. This innovative methodology has revolutionised the way sterilisation cycles are processed.”
