Calibration Gas Standards
For Petrochemical and Refinery Lab & ProcessChemtron Science Labs offers a complete line of Calibration gas and liquid standards from a single source allowing you to save time and money by consolidating vendors and centralizing responsibility
Petro-Refinery Calibration Gas Production Brief Process
- Before manufacturing speciality gas standards, requested components are first evaluated for potential phase problems using advanced computer modelling
- We evaluate component compatibility based on the requested Speciality gas Mixtures
- Next, Each Cylinder goes through proprietary cylinder passivation & Conditioning processes
- Then Standards are precisely blended to exacting specifications on highly sensitive gravimetric scales traceable to NPL-UK
- Finally, it undergoes advanced analysis using state-of-the-art analyzers to confirm the blended values designed to meet your need within the timeline you establish
