The Gasporox Technology
Innovative Laser Technology for Non-Destructive Gas Analysis
Gasporox offers a revolutionary approach to package quality inspection through advanced laser-based gas sensing. Our core technology is based on tunable diode laser absorption spectroscopy (TDLAS). This allows for non-invasive, non-destructive analysis of gas content inside packages.
Laser light passes through the sample, detecting gas types and concentrations without altering or opening the package. This enables fast, reliable testing in critical applications across the food, beverage, and pharmaceutical industries.
Common inspection scenarios include:
- Headspace gas analysis in sealed packages
- Leak detection in rigid and flexible containers
- Gas sensing in porous or absorbent material
Seamless Integration
Gas analysis
Gasporox laser sensors are designed to be embedded directly into production lines as individual quality assurance/inspection machines or as part of packaging machinery. Our OEM components enable manufacturers to integrate real-time gas analysis for enhanced quality control and regulatory compliance.
The packages can be any type of bag, bottle, vial or tray for the food or pharmaceutical industry, whether transparent or non-transparent and made of materials such as plastic, glass, foil, carton or paper.
Leak Detection
Gasporox laser sensors can also determine whether a package is leaking or not and with our concept, even microscopic leaks can be detected. The packages can be any type of bag, bottle, can, tray or vial for the food or pharmaceutical industry. The packages can be made of virtually any material.
Instruments
We also offer a wide variety of instruments ready for the end user, to be used at-line for quality inspection, or in laboratories for development and research (R&D).
Powered by Tunable Diode Laser Absorption Spectroscopy (TDLAS)
Gasporox technology is built on the scientific principle of Tunable Diode Laser Absorption Spectroscopy (TDLAS). This technique allows for:
- Precise measurement of gas species like oxygen (O₂), carbon dioxide (CO₂), and water vapour (H₂O)
- Ultra-low detection limits (down to parts-per-billion)
- Additional pressure measurements in controlled environments
TDLAS is superior to traditional gas sensing methods in sensitivity, selectivity, and speed, making it ideal for critical applications where headspace composition or leak integrity is essential.
Use Cases of Gasporox Technology
Headspace Analysis (HSA) / Headspace Gas Analysis (HGA)
Measure gas concentrations in sealed packages to verify modified atmosphere packaging (MAP), validation of headspace gas composition, or verification of sterile gas environments.
Container Closure Integrity Testing (CCIT)
Detect microleaks in pharmaceutical containers, ensuring product sterility and patient safety.
Leak Detection in Food and Beverage Packaging
Identify defective seals or leaks in flexible or rigid packaging, ideal for preserving shelf life and reduce recalls of food and beverages.
Innovations at Gasporox
GPX Porosity – Non-Destructive Porosity Measurement for Pharmaceuticals
Our latest innovation, GPX Porosity, introduces a novel method for analysing the porosity of pharmaceutical materials such as tablets and ribbons, without destroying the sample.
Traditional porosity measurement methods are destructive, time-consuming, and often require complex laboratory procedures – including weighing, toxic solvents, and specialised equipment. In contrast, GPX Porosity offers a non-invasive, at-line solution that is:
- Fast and suitable for real-time process environments
- Accurate without requiring extensive calibration
- Operator-friendly, requiring no sample preparation or lab access
This breakthrough is made possible by combining our expertise in TDLAS, GASMAS (Gas in Scattering Media Absorption Spectroscopy), and TOF (Time-of-Flight) technologies. The result is a unique system capable of measuring optical porosity during roller compaction or after tablet formation, making it ideal for GMP compliance, scale-up, and equipment validation.
