Validation of Horizon Technology Disk Extraction Technology for US EPA Wastewater Method 625.1
2 Oct 2018This application note presents the data collected as part of the demonstration of disk solid phase extraction validation for US EPA method 625.1. Nine different wastewater matrices were evaluated and tested against the criteria listed in Table 6 of method 625.1. The analytes chosen for evaluation were from Tables 1 and 2 in method 625.1, with a few extra analytes from Table 3. The analytes from Table 3 are omitted in this note because there was no acceptance criteria for comparison.

Environmental Monitoring and TestingEnvironmental monitoring and testing uses handheld portable analyzers, kits, spectrometers or chromatography systems for air, water, soil, food and other sample testing. Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity. Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Water PurificationThere are a number of water purification methods available to remove contamination from laboratory water. These systems include demineralization, reverse osmosis, filtration and ultrafiltration. A combination of methods is sometimes necessary to achieve purified water suitable for use in experiments.Waste WaterWater AnalysisAnalytical methods used to test the purity of drinking water include determining the level of contaminants abides to the level set by the Environmental Protection Agency (EPA).Environmental ContaminationContaminants in the environment are harmful chemicals that are present in the air, land and water. These include pesticides, pharmaceuticals, persistent organic pollutants (POPs) and many more.
