Environmental Testing

Drinking Water Anions and Disinfection Byproducts

EPA Method 300.0 Part A covers the common inorganic anions in drinking water and wastewater: fluoride, chloride, nitrite, bromide, nitrate, phosphate, and sulfate. Part B covers the disinfection byproducts bromate, chlorite, and chlorate. EPA 300.1 measures the same analytes with shorter run times. Both methods run on an ion chromatography system with conductivity detection.

Bromate and Oxyhalides

Bromate forms when water containing bromide is treated with ozone, and it is regulated at low µg/L levels. EPA 317.0 and 326.0 detect bromate at trace levels using postcolumn reaction and UV/Vis detection. EPA 302.0 uses a two-dimensional IC configuration to measure ultra-trace bromate in high ionic strength samples. ISO 15061 covers bromate determination in water by ion chromatography.

Perchlorate

EPA 314.0 determines perchlorate in drinking water by ion chromatography with conductivity detection. EPA 314.1 adds inline concentration and matrix elimination to reach lower detection limits in high ionic strength samples. EPA 314.2 uses two-dimensional IC for confirmation.

Hexavalent Chromium

EPA 218.6 and 218.7 measure hexavalent chromium by ion chromatography with postcolumn derivatization and UV/Vis detection at 530 nm. EPA 218.7 is optimized for the lower concentrations found in drinking water.

Haloacetic Acids by IC-MS/MS

EPA 557 determines haloacetic acids, dalapon, and bromate in drinking water by IC-MS/MS. Samples are injected directly with no derivatization or extraction. The method runs on an ion chromatograph coupled to a triple quadrupole mass spectrometer.

Waste Matrices

EPA 9056A determines inorganic anions in aqueous waste, extracts, and solid waste leachates by ion chromatography with conductivity detection.

Air Quality: AQMD 25.3

South Coast AQMD Method 25.3 measures low concentrations of non-methane, non-ethane organic compounds in source emissions. It is used for compliance testing at facilities regulated by the South Coast Air Quality Management District.

System Configuration and Support

Each environmental testing lab equipment system is configured for the specific EPA or AQMD method it will run. Systems are refurbished, tested, and backed by Alliant Scientific’s warranty. Consumables are not included, but our team helps you select the correct ones for your method so you can order them directly. Installation, training, and service contracts are available. Method references are published by the U.S. EPA in its drinking water analytical methods list.

Choosing the Right System for Your Method

Selecting environmental testing lab equipment starts with the method your lab must follow. Methods for common anions, perchlorate, and hexavalent chromium run on ion chromatography systems, while methods such as EPA 557 require an ion chromatograph coupled to a mass spectrometer. Sample matrix, required detection limits, and expected sample volume also determine which configuration is the right fit.
