Metals by ICP-MS (EPA 200.8 and 6020B) measurement context
Inductively coupled plasma mass spectrometry. Atoms in the sample are ionized in an argon plasma, and the ions are separated and counted by their mass; it is used when lower concentrations need to be measured. Elements we test: aluminum, antimony, arsenic, barium, beryllium, cadmium, chromium, cobalt, copper, lead, manganese, molybdenum, nickel, selenium, silver, thallium, vanadium and zinc, singly or as a scan. Zirconium is also measured by ICP-MS using the EPA 200.8 procedure. Water results are reported as µg/L. Solid samples are tested by EPA SW-846 Method 6020B.
Define the element list and fraction
Name the elements and state total, total recoverable or dissolved preparation as required. Filtration and preservation belong in the collection plan, and reporting limits must support the project criteria.
Include the complete project requirement
Provide the matrix, target analytes, required method, fraction, units and reporting limits. Include the permit or monitoring instructions where results will support a regulatory submission. Naming this method does not establish blanket compliance eligibility.
Resolve collection before sampling
Use the bottle, preservation and delivery instructions assigned to the agreed scope. Identify each location and collection time, and document any deviation. The final analytical plan must fit the submitted material and its intended use.
