EARL is equipped with the following major instruments:

SOLAAR M6 Atomic Absorption Spectrometer

Atomic Absorption Spectrometry(AAS) is the principal instrumental technique used for major and trace metal analyses (both metals and some metalloids). Flame AAS is the most cost-effective analytical technique for common metals analyses; Graphits furnace(GF)AAS is better for trace metals; Cold vapor(CV) AAS is for mercury and hydride generation(HG)AAS is used for the determination of some metalloids like arsenic, selenium and tellurium which can generate hydride.

Dionex DX-120 Ion Chromatography with AS50 Autosampler

Ion chromatography is used for measuring anions in solution. The commonly measured anions are: fluoride, chloride, nitrate, phosphate and sulfate. But also nitrite, bromide, iodide and accetate can be analyzed.

SHIMADZU TOC-VcsN Total Organic Carbon Analyzer

The SHIMADZU TOC-V is designed for the measurement of total carbon(TC), inorganic carbon(IC) and total organic carbon(TOC=TC-IC). The SSM-5000A Solid Sample Moduls is for the analysis of solids, sludges and slurries.

LECO SC-432DR Sulfur Analyzer

A non-dispersive infrared(NDIR) digitally-controlled instrument designed to measure the sulfur content in a wide range of organic materials including coal, coke and oil, as well as some inorganic materials such as soil, cement and limestone.
