ABSTRACT
When developing new methods for 40 CFR Part 136 compliance, it is important that the new method obtains statistically equivalent, or better, results as the currently approved methods. New on-line analyzer methods will not be laboratory methods, meaning some of the normal QA/QC of the new methods will differ somewhat from the laboratory methods. Included in this difference is sampling, sample preservation, and holding time. We know that for some parameters the sampling and preservation process can change the results. This presentation discusses the difference and potential problems in attempting to get comparability data between on-line and laboratory methods.
