Analytical Chemical Testing by Type

New Jersey Laboratories offers analytical testing following USP, FCC, and in-house methods, as well as any proprietary methods provided by our clients upon request. If you require custom methods, we will work with you to create a method that suits your needs.

The following are some examples of tests we perform. Please contact us if you seek a particular type of testing not listed.

Analytical Chemical Testing by Type

Elemental Analysis (Heavy Metals/Metals)

Elemental analysis is a fairly new type of testing performed on heavy metals that is quickly growing in demand. As of January 1, 2018, heavy metals testing by general chemistry is no longer considered a viable method of analysis for heavy metals and the FDA has begun requiring elemental analysis to validate heavy metal content.

NJ Labs is experienced and skilled in elemental analysis, and we will work with you to meet your testing requirements.
