Mycotoxin LC/MS/MS Screen

Mycotoxin screen by liquid chromatography- tandem mass spectrometry (LC/MS/MS). This screen is for corn, grains, silage, forage, hay, DDGs, soybean meal, dry pet food, and TMR with lower detection limits. Mycotoxins tested: Aflatoxin B1, B2, G1 and G2, T-2 toxin, Ochratoxin A and Sterigmatocystin at 20 ppb (0.02 ppm). Fumonisin B1, B2, HT-2 toxin, and DON (vomitoxin) at 200 ppb (0.2 ppm). Zearalenone at 100 ppb (0.1 ppm).

Additional Instructions

This test replaces the full mycotoxin screen previously offered.

Note: The lab can no longer analyze corn gluten or high protein corn concentrates (for example, Empyreal 75) for mycotoxins because of gelling of the extract during analysis that obstructs the instrument columns and can also solidify in the vials and flasks.
