OGI quantification is a measurement of Mass Flow Leak Rate (MFLR)(the size) of a leak or concentration in ppm.

Challenges of OGI quantification: Quantifying leak rate using OGI is extremely challenging. EyeCSite algorithm takes many aspects into account.

Quantifying a compound: In order to quantify a compound, the detected normalized contrast at each pixel is converted into a concentration path length measurement (ppm), using  the compound’s reference response curve.

Specific reference curve: Each compound has its own specific response curve. Opgal has developed a special algorithm which detects the difference in each curve in order to provide an precise calculation.
