Acetaldehyde (C2H4O) is an organic chemical compound, commonly used in various manufacturing facilities or chemical plants as raw material, intermediate or final product. It can cause serious damage on human health and is classified as a group 1 carcinogen (International Agency for Research on Cancer, IARC).
Nevertheless, acetaldehyde is indispensable in many industrial processes, especially as a basic material for the chemical synthesis in the production of acetic acid, acetic anhydride, butadiene, acrolein or pentaerythritol. Moreover, it is an essential ingredient in several chemical products. As a plasticizer for synthetic materials it occurs for example in PET bottles, having beside the health risks a negative impact on the taste quality. In addition, acetaldehyde occurs in binding agents for coatings, perfume, fuel, as a preservative and in the production of fire-resistant paint, paper or explosives.
With its GC-IMS device G.A.S. developed a highly selective and sensitive measuring system for rapid monitoring of acetaldehyde down to the low ppb range.
IMS-detector offers outstanding sensitivity, a second dimension of separation (full orthogonality) and is free from licencing
