The HGA device (Headspace Gas Analyzer) has been designed and manufactured to perform a fully automatic, non contact and non destructive inspection of containers filled with freeze-dried products or powder. Based on TDLAS spectroscopic technology, the laser is modulated in frequency to assure a more accurate, stable and reliable measurement.

The system can discern oxygen-free (good) containers from the ones contaminated by oxygen due to leakage or process fault.
