GRAHAM MATTHEWS AND ASSOCIATES (CAGM) LABORATORY
Sediment Mass Results
Results include determination of sediment mass. Target values are determined gravimetrically during sample preparation.
Median percent differences are calculated using all submitted analyses by participants for each sample class.
Upper and lower control limits are +/-3 f-pseudosigma from median, respectively. F-pseudosigma = (Interquartile range)/1.349.
Reported laboratory results percent difference = (((Reported value - Target value)/(Target value)) * 100).
