A series of gas regulators and switchovers from this company have been designed specifically for applications using reactive and corrosive gases. The regulators and switchovers are treated with a proprietary deposition process that impregnates all wetted surfaces of 316 stainless steel with an amorphous silicone layer. Known as SilcoNert technology, the silicone deposition process renders the stainless steel 100 time more inert than 316 stainless steel alone, the company says. The treated gas apparatus is designed for handling reactive mixtures containing hydrogen sulfide, methyl mercaptan, nitric oxide, sulfur dioxide and reduced sulfur in any application requiring rapid and accurate analysis of low-level sulfur and mercury. This includes a wide range of applications, including chromatography and beverage testing, natural gas and automotive emissions monitoring. — Concoa Precision Gas Controls, Virginia Beach, Va.
