Chemical Analysis
MEIC’s unique expertise and
capabilities provide analytical
services in chemical trace analysis
(CTA). The scientists and technical
staff in MEIC laboratories can analyze
diverse samples to give in most
cases trace level chemical
composition (into minimum detection
ranges in the parts per million (ppm),
parts per billion (ppb) and parts per
trillion (ppt) level ranges using an
extensive range of state-of-the-art
instrumentation and analytical
techniques.

Chemical and Environmental
Analysis
Our highly experienced technical staff and test laboratories are equipped to help our customers
identify their waste stream for known contaminants. A chemically characterized/identified waste
(effluent) can save you considerable time and money when disposal is an issue.
Do you know what your
industrial effluent or waste
is made up of ?  
You may be throwing precious
materials in the waste water
stream or harmful chemicals
endangering aquatic life and
nature.  Or even worse you may
be breaking the environmental
laws.
Our labs can provide you a
detailed analysis of your sample
and help you decide what should
go in your waste stream.
On the other hand, if you are a
water services provider or a
user of water from the well and
want to know the quality of your
water sample, you have come to
the right place as our trained
staff will help you quickly and
professionally.
Our analytical expertise is useful
in several situations and to
numerous organizations: waste
site clean up (remediation
process), water disposal,
industrial effluent, well water,
river water, lakes, natural water
streams, sea, public pools, food
and beverages, food industry,
chemical industry, dye industry,
semiconductor industry, farming,
military, compliance agencies,
etc.
* Federal Requirement for all
home sales that derive drinking
water from a private well. FHA
loans may also require lead
analysis.
