L53488-01 NG478037 Cyanide,WAD SM4500-CN I,E-Colorimetric wl 06 Sample was received above recommended temperature.
distillation
SM4500-CN I,E-Colorimetric w/ RA Relative Percent Difference(RPD)was not used for data
distillation validation because the.concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
WG479202 Fluoride SM450OF-C Q6 Sample was received above recommended temperature.
WG479075 Nitrate/Nitrite as N M353.2-H2SO4 preserved Q6 Sample was received above recommended temperature.
M353.2-H2SO4 preserved RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
WG478702 Phosphorus,total M365.1-Auto Ascorbic Acid Q6 Sample was received above recommended temperature.
(digest)
M365.1-Auto Ascorbic Acid RA Relative Percent Difference(RPD)was not used for data
(digest) validation because the concentration of the duplicated
sample is too low for accurate evaluation(<1 Ox MDL).
WG478042 Residue,Filterable(TDS)@180C SM2540C Q6 Sample was received above recommended temperature.
SM2540C RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<1 Ox MDL).
WG477993 Residue,Non-Filterable(TSS)@105C SM2540D Q6 Sample was received above recommended temperature.
SM2540D RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
SM2540D Z3 Sample volume yielded a residue less than 2.5 mg
WG479255 Total Hot Plate Digestion M200.2 ICP-MS DJ Sample dilution required due to insufficient sample.
