"Blanc de poussières" dust blank Explanation: by the same token as measurement blank, baseline sample for measuring dust -------------------------------------------------- Note added at 52 mins (2009-09-01 15:12:02 GMT) -------------------------------------------------- http://www.epa.gov/waste/hazard/tsd/td/combust/pdfs/apxb0927... Run control pans: pan blank (dust blank) and solvent blank. Blank weighing pans without solvent or sample should be carried through the evaporation and drying process as a quality control check for each set of samples. Solvent blank samples consisting of concentrated reagent solvent should be analyzed in duplicate for each batch of samples. Sample weights should be corrected for blank weighing pan mass gain using the dust blank. |
