ACZ Laboratories, Inc. Inorganic Extended
2773 Downhill Drive Steamboat Springs, CO 80487 [phone] Qualifier Report
Thorin Resources ACZ Project ID: L86570
ACZ ID WORKNUM PARAMETER METHOD QUAL DESCRIPTION
sample is too low for accurate evaluation(<10x MDL).
WG586576 Molybdenum(1312) M6020B ICP-MS RD For a solid matrix,the duplicate RPD(spike or matrix)
exceeded the control limit,which is attributable to the non-
homogeneity of the sample.
Nickel(1312) M6020B ICP-MS 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).
WG586123 Nitrate/Nitrite as N(1312-DI) EPA 353.2-Automated HD Analysis is outside the intended scope of the method,which
Cadmium Reduction does not provide hold time information for soil extracts. No
hold time is observed for collection to extraction. The
referenced method hold time is observed for extraction-to-
analysis.
EPA 353.2-Automated 06 Sample was received above recommended temperature.
Cadmium Reduction
Nitrite as N(1312-DI) EPA 353.2-Automated HD Analysis is outside the intended scope of the method,which
Cadmium Reduction does not provide hold time information for soil extracts. No
hold time is observed for collection to extraction. The
referenced method hold time is observed for extraction-to-
analysis.
EPA 353.2-Automated Q6 Sample was received above recommended temperature.
Cadmium Reduction
EPA 353.2-Automated RA Relative Percent Difference(RPD)was not used for data
Cadmium Reduction validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
WG586679 Nitrogen,ammonia(1312-DI) M350.1 Auto Salicylate w/gas Q6 Sample was received above recommended temperature.
diffusion
M350.1 Auto Salicylate w/gas RA Relative Percent Difference(RPD)was not used for data
diffusion validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
WG586125 Phosphorus,ortho dissolved(1312-D1) M365.1-Automated Ascorbic RA Relative Percent Difference(RPD)was not used for data
Acid validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
WG586398 Phosphorus,Total(1312-DI) 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).
WG586211 Potassium(1312) M6010D ICP 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).
WG586253 Residue,Filterable(TDS)@180C(1312) SM 2540 C-2011 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).
WG586424 Residue,Non-Filter(TSS)@180C(1312-SM 2540 0-2011/2015 BF Target analyte in prep/method blank at or above the
DI) acceptance criteria. Target analyte was not detected in the
sample[<MDL].
SM 2540 0-2011/2015 DJ Sample dilution required due to insufficient sample.
SM 2540 D-2011/2015 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).
SM 2540 D-2011/2015 Z3 Sample volume yielded a residue less than 2.5 mg
WG586576 Selenium(1312) M6020B ICP-MS 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).
Silver(1312) M6020B ICP-MS 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).
WG586211 Sodium(1312) M601013 ICP 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).
Strontium(1312) M60100 ICP ZG The ICP or ICP-MS Serial Dilution was not used for data
validation because the sample concentration was less than
50 times the MDL.
WG586304 Sulfate(1312-01) M300.0-Ion Chromatography HD Analysis is outside the intended scope of the method,which
does not provide hold time information for soil extracts. No
hold time is observed for collection to extraction. The
referenced method hold time is observed for extraction-to-
analysis.
