Pesticide residue analyses
We currently offer a 105-pesticide multi-residue screen with limits of detection <1 ng/g for most pesticides, depending on the matrix. In addition, in the first half of 2026, we’ll be adding a much-needed GC-MS/MS analysis for pesticides that can’t be detected via LC-MS/MS (e.g., pyrethroid insecticides).
Current sample types accepted
Large samples:
Pollen, bees, wax (ideal weight = 5 grams*)
Honey (7 grams*)
Leaves, soil (10 grams)
Silicone bands (whole band)
Other (contact us)
* about a golf-ball amount of compacted material or a tennis-ball amount of loose material.
Small samples:
Pollen (at least 0.3 grams)
Nectar (at least 0.3 grams)
Bee (at least 0.3 grams)
Other (contact us)
Other types of analyses
If you’re interested in LC-MS/MS or GC-MS/MS analyses for something other than pesticides, please contact us about your project. We have expertise with a wide variety of volatile and non-volatile small molecule applications. We’re ready to help you with your new, exciting projects!
Sample fees
As a Core Facility at Cornell, we are not allowed to make a profit. Thus, sample fees cover the cost of consumables, machinery, and labor. We revisit these fees every 12 months and adjust them to ensure the facility operates at a strictly break-even capacity. For all new samples received by our facility in 2024, our rates will be as follows:
Updated 105-pesticide multi-residue analysis via LC-MS/MS
Researchers within Cornell University: $40/sample
Clients outside Cornell University: $120/sample
*New* combined pesticide multi-residue analysis via LC-MS/MS and GC-MS/MS
Researchers within Cornell University: $60/sample
Clients outside Cornell University: $160/sample
All other LC-MS/MS or GC-MS/MS analyses
Researchers within Cornell University: $35/sample
Clients outside Cornell University: $90/sample
Method development for novel analyses that aren’t currently conducted in our facility
$100/hour
