Di-Ethyl-Hexyl-Sebacat (DEHS) is a common oil-based reagent that can be used to perform filter leak testing. The use of DEHS does not require any deviations from standard leak testing procedures such as ISO 14644-3. The user must verify that DEHS is selected as the challenge reagent on the photometer before performing a leak test. On the 2i, simply select DEHS from the menu of supported reagents. DEHS can be used with all ATI generators.
