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.

  • 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.

Other Residues Outside General Pesticide Screen

  • Glyphosate and its metabo­lite AMPA
  • Glufos­i­nate
  • Chlorate/​Perchlorate
  • Dithio­car­ba­mates
  • Methyl Bromide
  • Maleic Hydrazide
  • Ethephon

Residual Solvents

Solvents, alcohol and reagents are essen­tial to consumer goods processing, however, are regu­lated as harmful resid­uals with accept­able action limits.


  • Residual Solvents, USP 467
  • Residual Solvents, Comprehensive


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
