Today, specialty gas manufacturers are expected to produce over 10,000 differents types of products. Quality control requires the use of a metrological method that is reliable, extremely sensitive and completely impervious to cross response.

The ProCeas Pure Gases, based on the patented OFCEAS (Optical Feedback Cavity Enhanced Absorption Spectroscopy) technology coupled to the patented low pressure sampling technology enables such measurements.

Measurement of any or all of these pure compounds and/or mixtures under these conditions:

- is reliable;

- is very low maintenance;

- is insensitive to cross response phenomena;

- has very low levels of detection;

- has response times measured in seconds;

- has a wide dynamic concentration;

- does not experience instrumental response drift (self-standardization);

- does not require regularly schedule re-calibration (self-calibrating direct measurement);

- does not require sample conditioning; and

- is a laser spectrometer capable of multi-components analysis.

Some examples are:

- Purity of methane (CH4); focus on the detection of water vapor (H2O)

- Purity of hydrogen (H2)

- Purity of nitrogen (N2)
