MultiResidue Screens

For broad pesticide screening, the Columbia Pesticide Profile (P2220) is the most comprehensive and economical profile in food and agricultural commodities.


In addition to our general-purpose screen, Columbia Laboratories specializes in pesticide screens and other groups of tests designed for specific commodities. Our customers often are key partners in the design of these profiles.

  • P2220 Multi-Residue Pesticide Profile
  • P3200 Onion Profile
  • P2401 Potato Profile
  • P3100 Hop Profile
  • P2451 Mint Oil and Leaf Profile



Agricultural commodities may require testing before, during, after harvest due to signs of stress or damage. We have developed a specific testing to help you investigate issues with a crop including vegetation, water and soil samples.

  • P2750 Herbicides screen
  • Polar Pesticide such as Glyphosate (roundup) and Glufosinate

Maximum Residue Levels for Your Market

Food products which will be exported to other countries must meet their pesticide MRL standards. We are able to help by displaying these MRL’s on your report. Most countries will perform their own testing on imported food products. However, if a violative residue can be detected before shipping, much expense can be avoided as a result of having the shipment rejected.

As you get results on specific residues, we will keep you aware of the acceptable levels of those residues in major global markets and the implications of results that exceed the MRL for your particular markets. Demand for comprehensive pesticide residue analysis for growers, processors and organic certifiers continues to expand as testing requirements for both domestic and export markets increase.

Myco­toxins are carcino­genic biprod­ucts of mold. They concen­trate and are perva­sive through processing. If myco­toxins are consumed, humans and animals can suffer severe illness and even death. Test for myco­toxins in food, feed, and cannabis commodities since they are likely to be stored under warm and humid conditions. Applic­able for any botan­ical that can grow mold. We offer vali­dated, accred­ited testing by LC-MS/MS to meet your testing needs.

  • Multi Myco­toxin Screen: Afla­toxin B1, B2, G1, G2, Deoxyni­valenol, Fumon­isin B1 & B2, Ochra­toxin A & B, T‑2 and HT‑2 Toxin, Zearalenone
  • Cannabis-Regu­lated Myco­toxins: Afla­toxin B1, B2, G1, G2, Ochra­toxin A & B
