Headspace  Analyzer
The FMS Headspace Analyzer is a non-destructive gas analyzer for monitoring headspace gas concentrations in sealed parenteral containers. This compact benchtop instrument utilizes a patented laser absorption technique developed with funding from the Food and Drug Administration. Headspace oxygen, moisture/pressure, carbon dioxide and water activity levels can be analyzed using this technology. 

Light from a near-infrared diode laser is tuned to match an internal absorption frequency of the gas molecule of interest and passed through the empty container headspace above the product. The amount of laser light absorbed is proportional to the gas concentration in the headspace. The measurement method is rapid and non-destructive. These characteristics allow for multiple measurements on the same sample enabling the accurate monitoring of headspace gas concentrations of a single sam...
