MEIC labs provide expertise and services in
trace elemental analysis (TEM) to clients . Our
experts can help you achieve identification and
quantification of trace elements, metals
elemental compounds, and species in a
sample. Sample and matrices that can be
tested for trace elements include organic,
inorganic, biological, contaminated polymers,
rocks, aqueous, and non-aqueous phase
materials.
Our instruments have ultra low detection ranges
for a diverse range of samples and sample
matrices using a host of in house analytical
instruments and techniques. Both quantitative
and semi quantitative trace element/metal
analysis are available down to the ppm, ppb,
and ppt detection levels, depending upon the
sample and technique used.
Solutions via Elemental analysis:
Trace and ultra-trace analysis
Raw material testing/compliance
Chemical specifications
testing/compliance
Composition assay and purity
analysis
QC screening
Product troubleshooting
Identifying unknowns
Elemental speciation
Metallurgical applications
