Frequently Asked Questions
-
What types of samples can be tested for pesticide residues?We analyze food products, plant materials, soil, surface water, processed ingredients, and agricultural inputs.
-
Can you detect low-level contaminants?Yes. Our mass spectrometry-based methods can detect pesticide residues at trace levels, well below regulatory thresholds.
-
Do you offer testing that meets export requirements?Absolutely. We help clients meet U.S., EU, and international MRL standards for export and import of agricultural goods.
-
How fast are results delivered?Standard turnaround is typically within 5–7 business days. Expedited service is available based on sample volume and urgency.
