What are the materials compatibility of the E-Z Tray with H2S?

We have H2S in the water and need to know compatibility (currently using a plastic/PVC solution). More generally, what are materials compatibility for your E-Z Tray systems?

We offer two lower flow polyethylene stripper models (these use stacking trays instead of the sliding trays). We also have the ability to fabricate any E-Z Tray model from aluminum and higher grades of stainless steel. The standard E-Z Tray is fabricated from grade 304 stainless steel. We can help in material selection if you provide a complete inorganic chemical analysis of the target water.
