GasSpect O2 sensor

Complete your production line with Headspace Gas Analysis (HSA)


fast and accurate

The Gasporox sensor series GasSpect offers non-destructive Headspace Gas Analysis to be integrated into an inspection machine. The sensors with its highly sensitive laser impresses with performance and precision. The GasSpect series comes in different variations depending on which gas to be inspected.

The GasSpect O2 sensor is laser-based HeadSpace Analysis (HSA) which is applied to numerous inspection functions that relates to container closure integrity testing (CCIT) and also process control. It measures non-destructievly the oxygen gas concentrations in containers and parenteral packaging such as vials, ampoules and can also be applied to other package formats.

Applications for the GasSpect O2:

The GasSpect O2 is suitable for inspection of pharmaceutical containers such as vials. It is mainly used for container closure integrity testing where oxygen sensitive products are inspected. The GasSpect O2 sensor can for example be used for detecting residual oxygen in liquid vials or leak detection of lyophilized vials and in other applications where oxygen levels is a key parameter.

The GasSpect O2 sensor can measure:

  • Residual oxygen
  • Air ingress measurements

The GasSpect optical gas sensors are 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 parenteral drugs. It is integrated and used in machines, systems and instruments to do 100% and lab testing of vials and ampoules in many parenteral packaging lines and labs. The great performance and robustness of the measurement is well proofed in the industry.
