Analytical Technology offers improved ozone system monitoring
Analytical Technology (ATi) has launched a system aimed at helping pharma organisations achieve regulatory compliance through improved monitoring of ozone systems.
Ozone is commonly used in the pharmaceutical industry for the disinfection of pharmaceutical grade water.
The Q45H/64 Dissolved Ozone Monitor is capable of measuring dissolved ozone concentrations as low as 0-200ppb full-scale down to 5ppb. While providing the sensitivity needed for demanding applications such as pharmaceutical grade water or semiconductor wash water, this technique can also accommodate high-range applications requiring 0-20 or 0-200ppm.
One important feature is that it can be calibrated using a traceable method approved by the International Ozone Association. Using a colorimeter and indigo dye reagents it is possible for users to carry out on site, in-situ calibrations.
Unlike traditional on-line colorimetric and most amperometric methods, the innovative Q45H/64 Monitor uses a highly selective, membrane-covered polarographic sensor that does not require the addition of chemical reagents. Dissolved ozone readings are easily achieved without measurement interference from other sample components such as residual chlorine. The need for maintenance is greatly reduced as the technology does not require the use of moving parts, meaning that there are no tubing breaks or pumps and motors that burn out. The technology has been designed with the flexibility to enable optional dual measurement capability and provides both dissolved ozone and pH analogue outputs.
