Laser EXP Headspace Gas Analyzer


A headspace gas analyzer designed and validated to demonstrate compliance with worldwide regulations. Uses a precise laser to perform 100%, non-invasive, non-destructive testing using TDLAS for quick, accurate, repeatable measurement of gas composition in the headspace of pharmaceutical products. Suitable for testing glass vials from 2R to 100R which contain liquid, powder, and lyophilized content.




  • Reliable, accurate CCIT results provide quality control of pharmaceutical products and process control of your production line
  • Validation made easy, with complete documentation for effortless demonstration of regulatory compliance
  • TDLAS test method delivers accurate, reliable, repeatable HGA results
  • Efficient design optimizes production floor space without sacrificing capabilities

Additional Benefits

  • Full validation performed by ISO-9001-certified Bonfiglioli Engineering to get you online quickly, with complete documentation to certify your compliance with regulations
  • Customizable and intuitive HMI with real-time display of statistics and raw data
  • Ewon connection and advanced alerts for easy troubleshooting and problem solving
  • System supports remote connectivity, enabling MES connection for in-house data collection and analysis and facilitating remote support from Bonfiglioli Engineering
  • Can be integrated into production line or positioned separately for post-quarantine testing
  • Designed with fewer moving parts to be simpler to operate and maintain than other HGA inspection machines


  • TDLAS (tunable diode laser absorption spectroscopy) is the only non-destructive HGA method, enabling 100% testing of valuable pharmaceutical products.
  • TDLAS involves transmitting a laser beam through the headspace of a sealed container onto a receiver. The receiver measures the absorption of the laser, indicating the composition of the headspace atmosphere including details such as oxygen concentration, humidity, and pressure. If analysis detects anything outside the desired atmosphere for the product being tested, the container is rejected.
  • The Laser EXP analyzer features a Class 1, 760 nm wavelength laser, and uses TDLAS to perform quick, accurate, repeatable HGA.
