Gas-related equipment manufacturer Witt-Gasetechnik has released a new inline gas analyser which checks the modified atmosphere of packages processed in tray-sealers and thermoformers before the packages are finally sealed.

The new MAPY VAC inline gas analyser checks the vacuum generated in the packaging machine first, then measures the incoming inert gas in the sealing tool itself. Thus, the measurement is performed in sync with the machine cycle.

The device accurately and reliably measures oxygen (O2), as well as carbon dioxide (CO2) (if required), in the 0 to 100 percent range. The measured values are displayed in increments of 0.01% for gas concentrations below 10% and in increments of 0.1% for gas concentrations above 10%. 

“The MAPY VAC was specially designed for tray-sealers and thermoformers”. Witt Managing Director Martin Bender explained. “If the individually definable limit values for O2 or CO2 are exceeded, an alarm is triggered, or the MAPY VAC halts the operation of the packaging machine immediately. The entire process is fully automated and extremely fast. This results in seamless and non-destructive inline quality control. For even greater safety, the new Witt analyser also checks the gas concentration in the packaging machine’s buffer tank.”

“The major benefit of inline analysis: If something goes wrong with the gas mixture, or as the protective gas is introduced into the packaging, the user recognises this immediately and is then able to intervene directly in the process to correct the problem. The use of this approach prevents ongoing malfunctions, with their resultant costly corrective actions later – which would include the repackaging of all products and disposal of the unusable packaging.”
