RELATED TO PRODUCT SPECIFICATIONS
Method Detection Limit (MDL): “The method detection limit (MDL) is defi ned as
the minimum concentration of a substance that can be measured and reported
with 99% confi dence that the analyte concentration is greater than zero and is
determined from analysis of a sample in a given matrix containing the analyte.”

Note that, “As Dr. William Horwitz once stated, ‘In almost all cases when
dealing with a limit of detection or limit of determination, the primary purpose of
determining that limit is to stay away from it.’”
