GPX1500 Film Food – Non-Intrusive MAP Gas Analyzer

Modified Atmosphere Packaging (MAP) is widely used in the food sector to guarantee the freshness and shelf life of food packages. This involves frequent reduction or increase of oxygen during the packaging process. As a part of the quality system, a HACCP scheme is implemented. The verification of the MAP process is monitored using an at-line measurement or a sampling process using lab equipment. These are often done by a destructive method. This process generates relevant cost and a risk of operator errors. Gasporox GPX1500 Film Food eliminates these drawbacks. The instrument’s non-destructive measurement abilities enable to return the samples to the production line with no waste, assuring savings in production costs. It is designed for non-destructive headspace gas concentration measurements in transparent food packages and pouches.

The GPX1500 Film Food is very compact and easy to use. It is designed to operate parameter-free allowing a reliable quality control both at-line or in a laboratory.  With a testing time below 10 seconds, it allows efficient testing of packages with high sampling frequency. The instrument is designed to be able to measure gas concentrations on small headspace volumes, with a minimum required headspace gas volume of 3 ml. It supports several types of transparent flexible packages, including sealed trays, thermoforms, bags, flow wraps, and many others, without the need for any special sample preparation or any parameter change.  The GPX1500 Film Food can be used for shelf life studies, instant spot-checks at-line as well as long-term studies on packages. Both O2 and CO2 analysers are available.

The operation of the instrument is very easy and straightforward. The package is placed on the instrument by the operator. The operator is lowering down the test head to touch the film. By pressing the measure button, the film is formed to access the headspace with the laser and the headspace gas concentration is measured. The gas concentration is displayed immediately on the HMI touch screen and logged internally. Single and continuous measurements can be done.

non-intrusive MAP Gas Analyzer


The GPX1500 Film Food optical gas instrument is based on 25 years of development and refinement of industrial laser gas sensors. The product utilizes Tunable Diode Laser Absorption Spectroscopy (TDLAS).

The laser sensor technology has been developed by Gasporox and Gasporox’s technology partner/supplier, and is used in many other industrial settings, including the petro-chemical, pharmaceutical, and energy industries.

The GASPOROX technology is already used more than 10 years very successful for the testing of pharmaceuticals and food packages. It is integrated and used in machines, systems and instruments to do 100% and lab testing of food packages in many modified atmosphere packaging lines and labs. The great performance and robustness of the measurement is well proofed in the industry.
