  • Headspace Gas Analysis (HGA) inspection process based on Tunable Diode Laser Absorption Spectroscopy (TDLAS) method to accurately quantify gaseous concentration levels. Diode laser beam transmitted through headspace region of the container and reflected back towards the receiver. LVA 600 sensors measure the laser beam absorption related to target gas concentration.

Quality Assurance

  • Equipment test method refers to:
    • EU GMP Annex 1 Manufacture of Sterile Medicinal Products, section 123: “Containers sealed under vacuum should be tested for maintenance of that vacuum after an appropriate, pre-determined period”
    • Testing method in conformity with provisions of USP- United States Pharmacopeia - General Chapter <1207> “Package Integrity Evaluation – Sterile Products” (USP 39-NF34): Laser-Based Gas Analysis is listed among the Deterministic Leak Test Technologies
    • Software designed to comply with FDA 21 CFR Part 11 and EU Annex 11
    • Standard containers set supplied for easy calibration and verification
