Calibration Gases
Our independently audited and certified laboratory uses NIST, USA traceable high accuracy scales combined with the state-of-the-art cylinder preparation techniques to ensure most accurate and stable mixture in the industry. Each blend conforms to a strict set of quality-assurance measures and standard operating procedures.
Our laboratories also employ most sensitive instrumentation and reference gases to accurately analyze all of the raw materials used in the manufacture of calibration gases. This allows for the correction of any cross contamination and ensures that our customers receive the most accurate mixtures possible. This is especially important in hydrocarbon mixtures where impurities can alter the final composition of mixture.
