Calibration Gas Mixtures

How do we manufacture and package our products?

We must precisely manufacture our customized calibration gas mixtures by involving several critical steps. In the first step, we must consider the chemical raw material purity and detailed impurity characterization. In the second step, we must calculate the phase behaviour for the calibration gas mixtures. In the third step, we must blend precise amounts of gas. In the final step, we must confirm the independent analysis of the last gas calibration mixture.

Before we begin, we first evaluate the requested specialty gas mixtures using advanced computer modelling for potential phase problems. Next, the specialty gas mixtures are blended to precise specifications on sensitive gravimetric scales. Finally, all the calibration weights are traced by the National Institute of Standards and Technology, which are evaluated with analyzers and gas chromatograph to confirm that the blended and analyzed values agree to the stated product specifications.

Every manufacturing stage in the calibration gas mixture supply is constantly measured, evaluated, and validated. Each calibration gas mixture undergoes seven specific stages in the manufacturing process: from the raw material analysis, final mixture certification, results measured and recorded, and compared to stringent quality control requirements as per individual mixture.

How do we make a difference?

As specialty gas manufacturers, we must monitor all the steps involved in manufacturing our products, i.e., calibration gas. We constantly examine the raw materials adjusted as per the provider’s specifications. Quality raw materials must be used to manufacture specialty gas, as this determines the specialty gases’ accuracy and composition. Furthermore, we constantly measure the quality of pure raw materials by analyzing every pure gas for possible impurities. This further ensures that our calibration gas is manufactured without unwanted substances and maintains its high quality.

We carefully analyze the calibration gas standards with several other standards to promote the specialty manufacturing procedure, which cements our position as premium calibration gas suppliers. But, unfortunately, most companies have few internal standards to intercompare products between themselves, or they do not optimize themselves with the crucial phases mentioned earlier. This causes the GC analysis to confirm inaccurate standards at the end; in other words, an erroneous calibration gas standard is generated.

We perform with both reputed third-party manufacturers and internal standards to intercompare products to maintain our quality standards. Also, cylinders must be prepared according to the individual calibration gas mixture. However, as several manufacturers only take one approach to cylinder preparation, calibration gases are often stored in unideal conditions. Therefore, we have developed multiple proprietary techniques that ensure optimum cylinder preparation for optimum performance.

Finally, we must remain committed to quality filling methods. We constantly evaluate our new filling techniques to determine the most accurate one for your requirements. Thanks to our constant evaluation, we assure you that our procedures would always ensure the highest-quality calibration gas standards in the market. Continuously examined by experts in the field, our products would always lead the way in specialty gas manufacturing. Get in touch with us at Alchemie Gases & Chemicals for more detailed information.
