Ei591 Total Sulfur Analyzer
Concentrator, Converter, and Electrochemical System

The revolutionary Ei591 Total Sulfur Analyzer passes sample gas through a sorbent tube that traps and concentrates the sulfur species, including mercaptans. A thermal converter then transforms the trapped sulfur species to SO2, and finally, an electrochemical cell measures the concentration of SO2.
Our twenty-plus years of experience designing quality gas measuring instruments combined with our worldwide leadership in sorbent trap technology has come together to provide a cost-effective, highly accurate and sensitive design that allows total sulfur measurements down to ppb levels, a first
for the industry.
