Chemical Testing Services Information

Chemical testing services test, analyze, and certify a wide range of chemicals for purity, chemical compatibility, and environmental impact. Larger companies often have in house testing capabilities, but independent labs are almost always needed to conform to regulation requirements. These laboratories can also provide solutions to impact a company's bottom line.

Most chemical testing services run physical tests such as appearance, boiling point, pH, melting point, viscosity, and freezing point. There are many other services available when testing chemicals, many of the services are listed in the table below.

Diffraction evaluates crystal structure, grain size, texture and/or residual stress.

Non-Destructive Testing

Non-destructive testing (NDT) examines materials without impairing their future usefulness.

Non-destructive testing

NDT is done in many industries from automotive to construction.

Particle Size/Sieve Analysis

Sieve analysis can be performed on organic and non-organic materials. The material is sent through a series of wire mesh cloths (sieves). The mesh has smaller openings as the material travels through them.

Sample retention holds samples for a period of time after testing. The supplier may retain the samples for an extended period of time for an additional storage fee.

Sunlight Exposure / Solar Simulation

Sunlight exposure or solar simulation testing evaluates a material or chemical product's resistance to UV or simulated sunlight exposure. UV resistant or high weatherability materials will not degrade as fast or at all after extended exposure to sunlight.

Umpire Testing

Umpire testing compares the test results of the same sample, which have been tested by different laboratories. Umpire assayers or referee testers compare the two or more other labs results to their own rigorous internal assays or tests. Interlaboratory comparisons, round robins, or proficiency testing services are a valuable continuous improvement tool that translates into improved measurement quality.

Waste characterization of a solid waste is an initial risk assessment step in a program for managing waste streams to meet RCRA guideline.

Chemical Testing Services Applications

Chemical testing services are used in almost all industries including, but not limited to aerospace, automotive, marine, medical, military, pharmaceutical, or packaging applications. Other test chemicals are used in electronic devices, semiconductors, or integrated circuits (ICs).

Chemical testing services is important in the medical industry to investigate tissue/material interaction. This service is also done on large construction sites to ensure the strength of building materials, on the soil of building sites to test for durability and safety of ground material, and in the food industry to test the safety of chemical compounds and the food packaging.
