Rapid, nondestructive, laser-based headspace analysis enables determination of headspace Oxygen, Moisture/Pressure, Carbon Dioxide and Water Activity. Using laser absorption, light from a near-infrared laser is tuned to match an internal absorption frequency of various molecules and passed through a glass sample container in the headspace above the product. The amount of laser light absorbed is proportional to the concentration of the specified gas in the headspace.
The benchtop headspace analyzers can be used throughout the product life-cycle, from Development to QC, to at-line and in-process control during Manufacturing.
Application of non-destructive headspace analysis can include:
- Oxygen monitoring of sensitive formulations
- Container Closure Integrity (CCI) testing
- Moisture determination of dry product
- Microbial contamination inspection
