Some of the features of the cyclone assembly are: a hydraulic upper knife valve and pneumatic lower knife valve for collecting and isolating the sample; a hydraulic hinge between the dump box and cone splitter that allows for easy cleaning; and a fixed cone splitter with primary and duplicate sample
We analyzed samples in batches of 12, with each batch consisting of 8 samples, 1 method blank, 1 duplicate sample
A duplicate sample
was also collected at RCC to determine variability of concentrations between samples.
It will test and confirm a reference sample to ensure that all sample preparation steps are within established limits; test and confirm a duplicate sample
to prove that the results can be repeated within established limits; and, if applicable, check a blank sample to test for equipment contamination," says Lischefski.
Core samples from the Klaza property were processed in 36 sample batches with each batch including two assay standards, two blank samples, and one duplicate sample
DAFF investigations are ongoing and results of analysis of a duplicate sample
collection was included in the study design for approximately 10 percent of all field samples, and of the total number of sediment samples (124) included in the study, 17 samples were collected in duplicate.
We had several duplicate sample
sets in the testing scheme.
Concentration ranges of positive samples are presented without averaging duplicate sample
Table 2 gives summary QC duplicate sample
results from the within-visit reliability substudy 2.
The method is also rugged, as demonstrated through the duplicate sample
analysis results obtained over several months.
All Lumina sample assay results have been monitored through a quality control / quality assurance ("QA/QC") program including the insertion of blind standards, blanks and the reanalysis of duplicate samples
