Calibration Gas Mixture - more emphatically a degree of measurement - is our prime product. Gravimetric filling method as per ISO 6142 where the components are added sequentially using traceable weights and improvised manometer method as per ISO 6146 are followed. For Analysis, various GC methods and direct analysis methods as per IS, ISO and ASTM standards are used in the laboratory. Laboratory is maintained as per ISO 17025 (NABL). For certification, ISO 6141-2015 is being followed.
All our Calibration Gas Mixtures are delivered with a calibration certificate compliant to ISO 6141. Due to our thorough approach to quality; we are able to trace every mixture back to its original filling data. This data includes identification of cylinders, production process, actual component weights and chromatographic analysis results. Measuring devices like weighing scales and pressure gauges are calibrated against tracesble weights and certified master gauges respectively on a regular interval. Further more the gas compositions are analyzed traceable to NIST or NPL references.
Preparation Tolerance defines the maximum permitted variation between the requested nominal concentration and the actual concentration supplied.
The Certification Accuracy defines the accuracy of the instruments used and method followed for analysis and certification. Standard uncertainty also calculated as and when required.
Final Pressure of the supplied gas depends on the vapor pressure of the component and its concentrationS. We supply at maximum pressure permissible for the particular composition of gases in a given container.
We Guarantee the homogeneity of the gas mixtures stable during the particular period of time. Selection of right cylinder and cylinder preparation followed rigorously to achieve stability.
We Manufacture wide range of Calibration Gas Mixtures write from two components to multi components mixtures as required by the user.
