Many specialty gas manufactures fail to monitor these steps closely enough to provide truly accurate calibration gas standards. Raw materials are accepted and adjusted according to the provider's specification sheet. This information is frequently misstated or inaccurate. Also, sub-par raw materials are often used in the manufacturing of specialty gases. This not only compromises the accuracy of the specialty gas, but could impact critical components on your analyzer. CSG starts with high purity raw materials and carefully analyzes each pure gas for potential impurities. This ensures a quality calibration gas standard that is manufactured free of unwanted impurities.

Careful analysis of the calibration gas standard inter-compared with multiple standards is a critical step in the specialty gas manufacturing process. Many companies may have few internal standards to inter-compare. Other companies may inter-compare with internal standards that fail to strictly optimize some of the critical phases mentioned above. The result can be an inaccurate standard confirmed by GC analysis. If both mixtures did not optimize the steps mentioned above, then the result is often a confirmed, but an inaccurate calibration gas standard is produced.

Cylinder preparation is another critical step often overlooked. Cylinder preparation should be based on the individual calibration gas mixture. Many manufacturers take a single approach to cylinder preparation, often resulting in less than optimal conditions for the calibration gas standard. Over the years, CSG has developed several proprietary techniques for cylinder preparation, making sure that each cylinder has been prepared to optimize the performance of specialty gas mixture.

Filling techniques vary greatly. Commitment to quality is the engine that drives our filling techniques. CSG constantly evaluates new filling methods to determine which techniques produce the most accurate results. Our continuous evaluations of new techniques ensure that you will receive the most accurate calibration gas standards available in the market.
