EPA-Approved Ozone Analyzer
Periodically Measure Lab and NoZone Enclosure Ozone Levels
An Affordable Way to Measure Ozone Levels
Ozone levels as low as 20 ppb negatively affect microarray results (1). The most reliable way to measure ozone at these low levels is to use an ozone analyzer that employs the UV photometric method of measurement. However, high performance ozone analyzers that measure in the ppb range are expensive. Also, only periodic measurements of ozone levels in the lab or within a NoZone Enclosure are normally needed.
SciGene has an affordable solution. Instead of purchasing an instrument that is used infrequently, SciGene offers to laboratories the ability to rent by the week a Model 49i Ozone Analyzer (Thermo Electron). This model is approved for use by the FDA for continuous monitoring of ambient levels of ozone in the low ppb range. It is perfectly suited for accurately measuring ozone levels in the lab and validating the performance of SciGene NoZone Workspaces.
Validate NoZone Workspace Performance
SciGene recommends that the ozone levels of the NoZone Workspace be measured during initial set up of the NoZone Workspace and then annually when seasonal levels of ozone are high, to ensure the ozone scrubber is working properly and that the enclosure remains well sealed. The Ozone Analyzer can be rented on these occasions to measure ozone levels in both the lab and NoZone enclosure as ozone levels.
Periodically Measure Lab and NoZone Enclosure Ozone Levels
The ozone analyzer comes calibrated from the factory to give accurate ozone levels without further adjustment. The unit is provided configured ready to “plug and play” without need to study a manual. Simply connect the air sampling tube to the unit and turn it on. Within a few minutes, ozone levels are reported on a large easy to read screen which is updated every few seconds. For record keeping, ozone data with date and time can be streamed to a computer via an Ethernet connection.
