Calibration & Linearity :

Our Marseille laboratory is accredited by COFRAC for the calibration and linearity control of gas analyzers which operate on the following principles :

• Flame ionization Detection ( FID )

• non dispersive infrared ( NDIR )

• UV Chemiluminescence

• UV Fluorescence

• Paramagnetic Susceptibility, ... .

Reference gas concentrations are obtained by diluting traceable gas mixtures in nitrogen or air.

Scope of COFRAC Accreditation

• CO2 from 0.66% to 66%

• CO from 2 ppm to 1%

• O2 from 0.66% to 66%

• NO from 2 ppm to 1%

• NO2 from 10 ppm to 1000ppm

• SO2 from 50 ppm to 5000ppm

• C3H8 from 1 ppm to 1%

• CH4 from 1 ppm to 1% and 0.66% to 66%
