Carbon Dioxide Quality Check (CDQC)

Carbon Dioxide is usually used in food & beverages industry to preserve the quality of food products and carbonization of beverages. 

Because of high demand of improved quality and purity of Carbon Dioxide (CO2), manufacturer must compulsorily install the impurity check analysers or quality check analysers. It is very challenging for analyser service providers & CO2 Manufacturers to calibrate these analysers for given impurity components.

Here, we at Bhoruka are constantly developing certified calibration gas standards prepared gravimetrically (ISO 6142) and analysed on very accurate Gas Chromatography.

Our Calibration gas Standards are widely used by CO2 manufacturer, system integrators & calibration service providers.

We offer all Types of calibration gases for CDQC analyser systems.

Calibration Gas Standards for Trace Oxygen
  • We can supply as low as 2 ppm O2 in CO2 or N2
  • Standard Calibration Gas for CDQC is 20 to 40 ppm Oxygen in Carbon Dioxide
  • The CO2 used will be free of HCs and Sulfides
Gas Standard for Zero Calibration of Total HCs/ Sulfides
  • Mainly High Pure Carbon dioxide is used for Zero Calibration
  • We supply High Purity Carbon Dioxide with traces of known impurities
  • Purity of Carbon dioxide (CO2) is 99.999%

High Pure Hydrogen (with <1 ppm THC) as Fuel Gas
