Metals by ICP-OES (EPA 200.7 and 6010D) measurement context
Inductively coupled plasma optical emission spectrometry. The sample (acid digested for total recoverable metals) is sprayed into an argon plasma, where each element gives off light at its own wavelengths, and the intensity of that light is measured against calibration standards. Elements we test: aluminum, antimony, arsenic, barium, beryllium, boron, cadmium, calcium, chromium, cobalt, copper, iron, lead, lithium, magnesium, manganese, molybdenum, nickel, phosphorus, potassium, selenium, silver, sodium, strontium, thallium, tin, titanium, vanadium and zinc, singly or as a scan. Sulfur and silicon (reported as silica if required) are run by the same ICP-OES procedure. EPA 200.7 is the water method; 6010D is the EPA SW-846 method for wastes and other samples. Mercury is measured by cold vapor (below). Reported as mg/L.
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.
