Pesticide Residue Testing
Tentamus QTS Analytical is your trusted partner for pesticide residue testing in food. As a UK-based, UKAS-accredited laboratory, we deliver fast, reliable, and regulatory-compliant testing services across a broad range of food categories — helping ensure your products meet maximum residue limits (MRLs) for the UK, EU, and global markets.
Food Categories We Test
We specialise in multi-residue testing for a wide range of food products. Our validated methods are suitable for both routine surveillance and targeted testing. Key product categories include:
We test fruits and vegetables including:
- Leafy greens (e.g. spinach, kale, lettuce)
- Root vegetables (e.g. carrots, potatoes)
- Berries, apples, citrus, avocados, and tomatoes
Pesticide residue testing is essential in fresh produce due to the high risk of pre- and post-harvest chemical applications.
We support the cereals and brewing industries by analysing:
- Barley, wheat, maize, oats, and rice
- Hops for brewing (including bittering and aroma varieties)
These matrices often require tailored methods due to their dense composition and specific regulatory thresholds.
We test dried products like:
- Raisins, apricots, dates, and figs
Pesticide residues may concentrate during the drying process, making testing especially critical for consumer safety and compliance.
We cover:
- Green, black, and herbal teas
- Culinary and medicinal herbs (e.g. basil, chamomile, mint)
- Black pepper, turmeric, cumin, coriander, and paprika
This category requires highly sensitive methods to detect residues in low-moisture, aromatic matrices.
Our Analytical Capabilities
Our laboratory uses the latest LC-MS/MS and GC-MS/MS technologies for the detection of hundreds of pesticide residues in a single run. All testing is performed under ISO/IEC 17025 accreditation using:
- Multi-residue screens
- High-sensitivity instrumentation for low-level detection
Our methods comply with key regulatory frameworks and enable you to make informed decisions about your products.
