This method describes a fast, simple, and direct injection
method to determine total and potential sulfate and total
chloride in butanol according to ASTM D7319-09. The
method described in this application note can reliably
quantify sulfate and chloride in butanol at 0.1 and
0.3 ppm, respectively, which is well below the ASTM
D4806-11A specification of 4 ppm for sulfate and 40 ppm
for chloride.
