EARL is equipped with the following major instruments:
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.
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.
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.
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.
