Research Report RR:D02-1614
The precision of this test method was determined by the statistical evaluation of the interlaboratory test results. For measuring total chloride, both methods of suppression provided a single precision statement. For total and potential sulfate, the data indicated two distinct statistical populations, reflecting use of the packed bed tri-chamber suppressor regeneration approach and the continuous suppressor membrane regeneration approach.
