ICP-Mass Spectrometer

Utilizes thee modes of operation, Standard, Collision and Reaction.  These modes gives the flexibilty and sensitivisty to overcome virtually any matrix and interference.

EPA 200.8

This method provides procedures for determination of dissolved elements in ground waters, surface waters and drinking water. It may also be used for determination of total recoverable element concentrations in these waters as well as wastewaters, sludges and soils samples.

200.8

EPA 6020

Inductively coupled plasma-mass spectrometry (ICP/MS) is applicable to the determination of sub-ug/L concentrations of a large number of elements in water samples and in waste extracts or digests. When dissolved constituents are required, samples must be filtered and acid-preserved prior to analysis.

RCRA 8 Metals

 

The Resource Conservation and Recovery Act (RCRA) monitors 8 heavy metals commonly refered to “RCRA 8’s”.

The RCRA 8 heavy metals include Arsenic (As), Barium (Ba), Cadmium (Cd), Chromium (Cr), Lead (Pb), Mercury (Hg), Selenium (Se), and Silver (Ag).

 

Priority Pollutant 13

EPA has a set of chemical pollutants they regulate. There is 13 Priority Pollutants metals (PP 13) which consist of Antimoney (Sb), Arsenic (As), Berillyum (Be), Cadmium (Cd), Chromium (Cr), Copper (Cu), Lead (Pb), Mercury (Hg), Nickel (Ni), Selenium (Se), Silver (Ag), Thallium (Tl), and Zinc (Zn).

Cold Vapor Atomic Fluorensence (CVAF)

The QuickTrace M-8000 Cold Vapor Atomic Fluorescence (CVAF) Mercury Analyzer is ideal for ultra-trace to sub-mg/L mercury quantitation.

EPA 245.7

This method is for the determination of mercury in filtered and unfiltered drinking water, surface and ground waters, marine water, and industrial and municipal wastewater.

245.7

Method 7471B

This method is a cold-vapor atomic absorption procedure for measuring the Mercury in soils, sediments, bottom deposits, and sludge-type materials.

Determination of Hexavalent Chromium

All hexavalent chromium Cr(VI) compounds are strong oxidizing agents and considered toxic and potentially carcinogenic. Hence, chromates are regulated in the environment and are a primary drinking water contaminant in the United States.

SM 3500-Cr B

The colorimetric method is useful for the determination of hexavalent chromium in a natural or treated water in the range from 100 to 1000 ug/L. This range can be extended by appropriate sample dilution or concentration and/or use of longer cell paths.

SM 3500-Cr B

Method 218.6

This method provides procedures for determination of dissolved hexavalent chromium (as CrO4 2-) in drinking water, groundwater, and industrial wastewater effluents.

Method 218.6

Method E 7199

This method provides procedures for the determination of hexavalent chromium in drinking water, groundwater, and industrial wastewater effluents. Samples containing high levels of anionic species such as sulfate and chloride may cause column overload. Samples containing high levels of organics or sulfides cause rapid reduction of soluble Cr(VI) to Cr(III).

E 7199

Method 3060

Method 3060 is an alkaline digestion procedure for extracting hexavalent chromium [Cr(VI)] from soluble, adsorbed, and precipitated forms of chromium compounds in soils, sludges,
sediments, and similar waste materials.
