What We Offer

Established in 1956, Midwest Microlab, Inc. is equipped to provide rapid accurate organic microchemical analysis to research and industry. Specialties include analysis for Carbon, Hydrogen, Nitrogen, direct Oxygen, and halogens including Fluorine. We also offer Elemental Analysis is requested for many different areas of research for: Coal Analysis, Pharmaceutical Research, Agricultural Chemicals, Resins, Cosmetics, Oceanography and more.

Air Sensitive 

Many samples currently being tested for purity are those that readily oxidize when exposed to air. Most of these samples are also extremely sensitive to environmental moisture. For an accurate evaluation of purity, air-sensitive samples require weighing under an inert atmosphere.

Why Midwest Microlab

Fast service, results are often available within 24 hours without a Rush charge.
Competitively priced services for the industry.
Micro analysis provides the most sensitive method for determining the purity of a compound.
Accurate to 0.3% for analysis.
Less than the cost of maintaining an in-house lab.
Results from micro analysis can help establish the structure of a compound.
Elemental analysis typically requires only 5 mg. of sample.
