Pesticide Screen (GC/MS)

Detection and identification of a variety of chemicals including organophosphates, organochlorines, carbamates, industrial pollutants, polycyclic aromatics, aliphatic hydrocarbons, miscellaneous pesticides, some natural products and some drugs using gas chromatography – mass spectrometry (GC/MS). 

Samples are screened using multiple instrument libraries containing mass spectra for thousands of compounds. Positive identification of a suspect sample is made by comparing sample mass spectra with that of a certified reference standard. 

One or more of the following: 

• 30 g GI content
• 10 g bait (source material)
• 40 g forage or hay
• 20 g liver
• 10 g crop contents
• 20 mL water
• 20 g soil
• swabs

Sealed, leak-proof plastic bag or container.

Label all samples. Ship overnight on cold packs.

Turnaround time may be dependent upon the availability of a reference standard.

Samples must be received in the testing lab / location by 3:30 p.m., otherwise samples will be held until the next scheduled test day.
