Monitoring of trace impurities in pure gases and mixtures is becoming increasingly important, as the industry sectors that these products serve continues to grow, with each sector bringing different requirements and standards for product quality.

From high purity gases demanded by the Semiconductor industry, food grade gases such as CO2 for the food and beverage market, to gas mixtures e.g. Diving Gases, ESS has a wealth of experience and give you products that will ensure the most stringent quality standards are met. We offer two systems for this application sector, these being the GasTrace and the UltraTrace-PPT, the latter being our flagship instrument for instances where there is requirement to measure impurities in the low parts per trillion (PPT) ranges.
