The composition of the mixtures available is practically infinite. It is restricted only by the physical and chemical properties, health, safety norms and the Stability and quality of the final mixture. 

At Chemtron Science Laboratory, we offer our Clients any desired Preparation Tolerance and Certification Accuracy depending on the mixture components. We prepare mixture using highly accurate Gravimetric / Volumetric Techniques traceable to National Physical Laboratory standard masses. We have advanced imported computerized Gas Chromatograph System which enables higher accuracy and precision for each Gas Mixture.
