GPX1500 Film Food

Non-destructive Headspace Analyzer for Modified Atmosphere Packaging (MAP)

GPX1500 Film Food

Fast, Accurate, Non-intrusive, and Non-destructive

The GPX1500 Film Food is a compact, benchtop headspace gas analyser developed for non-destructive and non-intrusive measurement of oxygen (O₂) or carbon dioxide (CO₂) in flexible Modified Atmosphere Packaging (MAP) for food products. Using advanced laser-based technology, it delivers precise and repeatable measurements for both high- and low-concentration MAP applications across a wide range of packaging formats.

This instrument helps ensure product integrity, reduce waste, and support food safety and shelf-life objectives by enabling testing without compromising the packaging or its contents.

How does it work?

The GPX1500 Film Food uses Tunable Diode Laser Absorption Spectroscopy (TDLAS) to perform fast, accurate and non-destructive headspace gas analysis (HSA) in transparent food packaging.

During measurement, the package is placed on the sensor head, which gently creates a vacuum on the film surface to form a temporary bubble. A laser beam passes through this bubble to analyse the internal gas content, either oxygen or carbon dioxide, without damaging the package. The tested product can be returned to the production line or stored for later verification, supporting continuous and sustainable quality control.

Applications for the GPX1500 Film Food

The GPX1500 Film Food provides accurate and repeatable gas measurements for MAP formats including:

  • Trays
  • Thermoformed containers
  • Flow-wrapped products
  • Form-fill-seal (FFS) bags
  • Other flexible film packaging formats

Which makes it ideal for use in: Product development and validation, At-line quality control (QC), Small-scale production environments, and a natural addition to any Hazard Analysis Critical Control Point (HACCP) concept.

The GPX1500 Film Food is well suited for different oxygen-sensitive food products such as: Fresh meat, Ready meals, Dairy products, Baked goods, Processed foods.

Available variations

  • GPX1500 Film Food O₂ – Measures oxygen (O₂) concentration in the headspace of sealed food containers. Ideal for MAP applications involving oxygen-sensitive products.
  • GPX1500 Film Food CO₂ – Accurately measures carbon dioxide (CO₂) levels in sealed packaging to support quality control in CO₂-modified atmospheres.

Product-specific adaptations of the instrument are available on request.

Technology

The GPX1500 Film Food instruments are built on more than 25 years of development and refinement in industrial laser-based gas measurement. The system uses Tunable Diode Laser Absorption Spectroscopy (TDLAS), a highly reliable and precise method for non-destructive headspace gas analysis.

Developed by Gasporox in collaboration with its technology partners, this laser sensor technology is widely used in demanding industries such as pharmaceuticals, petrochemicals, and energy.

Gasporox’s laser-based headspace analysis has been successfully deployed for over a decade in pharmaceutical manufacturing. It is integrated into fully automated inspection systems and benchtop instruments for 100% in-line and laboratory testing of vials, ampoules, and other parenteral packaging formats. The performance and robustness of the system have been validated through extensive real-world use.
