Laser headspace residual oxygen measurement system

Luose LROM110 laser headspace residual oxygenMeasurement system (online version) for ampoules orResidual sterile preparations packaged in penicillin bottlesMaintain oxygen content for non-destructive and non-invasive purposesOnline testing to confirm packaging seal integrity inspection (CCIT)

Technical principle: Aseptic formulation packaging using vacuum freeze-drying or nitrogen filling processes is a typical exampleThe composition of the headspace gas inside the bottle is different from that of the background gas - airPackaging forms with significant differences, if the bottle leaks, the gas composition in the headspace tends toApproaching the background gas, this allows for analysis of the oxygen concentration in the headspace gasTo distinguish between qualified products and leaked products.

*Non destructive non-destructive testing based on tunable laser absorption spectroscopy technology
*Low power consumption
*Small size, easy to integrate
*Maximum detection speed of 600 bottles per minute
*No need to blow nitrogen gas

Technical Details
The laser headspace residual oxygen measurement system is a technology based on tunable laser absorption spectroscopy (TDLAS) for detecting specific gas content in the top space of containers, and is also the most widely used spectral absorption technology that can achieve high detection sensitivity.
The frequency of the laser matches that of the target molecule

The amount of absorbed laser depends on the concentration of target molecules in the sky
detector

Select a laser that matches the frequency of the target detection gas molecules. When the laser passes through the headspace gas of the container to be detected, the target gas molecules absorb photons and produce electronic transitions, forming energy absorption of the laser spectrum. The higher the gas concentration, the stronger the spectral absorption. By analyzing the absorption of the laser spectrum, the content of the target gas can be calculated.
