Reanalysis for the <br />WG355271 Chloride <br />M300.0 - Ion Chromatography <br />N1 <br />required dilution was past holding time. <br />SM2540C <br />HE <br />Analysis performed past holding time. Method holding time <br />is less than or equal to 7 days and sample was received <br />with less than half of the holding time remaining (refer to <br />WG355667 Fluoride <br />SM4500F -C <br />M2 <br />item C5 of ACZ's Terms & Conditions). <br />WG355271 Sulfate <br />M300.0 - Ion Chromatography <br />DC <br />Sample required dilution. Non - target analyte exceeded <br />SM4500F -C <br />RA <br />calibration range. <br />L15611 -06 WG355330 Copper, dissolved <br />M200.7 ICP <br />D1 <br />Sample required dilution due to matrix. <br />Manganese, dissolved <br />M200.7 ICP <br />M3 <br />The spike recovery value is unusable since the analyte <br />concentration in the sample is disproportionate to the spike <br />level. The recovery of the associated control sample (LCS <br />or LFB) was acceptable. <br />Zinc, dissolved <br />M200.7 ICP <br />D1 <br />Sample required dilution due to matrix. <br />M200.7 ICP <br />M3 <br />The spike recovery value is unusable since the analyte <br />concentration in the sample is disproportionate to the spike <br />level.
