Modern Hexane-Extractable Material (Oil and Grease) Analysis in Wastewater Samples
Initial precision was demonstrated by spiking four 1-L volumes with one Snip and Pour pre-measured standard, each (40 mg). The data for four replicates was collected for 47 mm Disks and 100 mm Disks. The average percent recovery is excellent and meets the criterion specified of 83–101% HEM recovery for both size disks. The standard deviation is better than the criterion specified of 11% for HEM.
