METHOD QUAL DESCRIPTION
L50149-01 NG467130 Calcium,dissolved M200.7 ICP M3 The spike recovery value is unusable since the analyte
concentration in the sample is disproportionate to the spike
level.The recovery of the associated control sample(LCS
or LFB)was acceptable.
WG467252 Chloride SM4500CI-E 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).
WG467461 Cyanide,WAD SM4500-CN I,E-Colohmetric w/ M2 Matrix spike recovery was low,the recovery of the
distillation associated control sample(LCS or LFB)was acceptable.
SM4500-CN I,E-Colonmetric 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).
WG467130 Manganese,dissolved M200.7 ICP M3 The spike recovery value is unusable since the analyte
concentration in the sample is disproportionate to the spike
level.The recovery of the associated control sample(LCS
or LFB)was acceptable.
WG467891 Nitrate/Nitnte as N 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)
WG467441 Phosphorus,total 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(<10x MDL)
WG467080 Residue,Non-FRerable(TSS)@105C 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)
WG467130 Sodium,dissolved M200.7 ICP M3 The spike recovery value is unusable since the analyte
concentration in the sample is disproportionate to the spike
level.The recovery of the associated control sample(LCS
or LFB)was acceptable
WG467210 Sulfate D516-02/-07-Turbidimetric 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).
