Meeting global Pharmacopeia challenges for purity monitoring

Medical gases are used for medical treatment and are regulated under the same rules as medicinal drugs. These regulations – typically covered in a publication called a Pharmacopeia – specify how each gas should be produced and validated, the acceptable purity level, and official measurement records. Purity assurance requires accurate, reliable gas analysis solutions.

Strict regulations require a powerful gas analysis solution

For example, under European Pharmacopeia (EP) rules, medical oxygen (O2) requires an assay measurement to ensure O2 purity is better than 99.5%, and impurity measurements of carbon monoxide (CO) and carbon dioxide (CO2). The impurities must be less than 5 parts per million (ppm) of CO and less than 300ppm of CO2. Paramagnetic sensing is specified for the O2 measurement, and Infrared Gas Filter Correlation (Gfx) for the other two results.

SERVOPRO Servomex MultiExact 4100

An advanced solution for purity assay and impurity detection

Servomex offers a combined solution for all three analytes, meeting EP standards and providing the measurement limits required. The SERVOPRO MultiExact 4100 is a multi-gas analyzer capable of monitoring up to four gas streams simultaneously. It can be fitted with a Paramagnetic cell for a highly stable O2 reading, and a customized Infrared Gfx sensor for CO and CO2.
