An ultra-high sensitivity quantification method of veterinary drugs residues in food
Veterinary drugs such as antibiotics, antimicrobials and hormones are necessary for therapy and prophylaxis in animal husbandry and food production. However, these chemicals can leave behind residues that persist in animal-derived foods and present potential food safety risks.
Consequently, many countries have established maximum residue limits (MRL) for pharmacologically active substances. For food testing labs, this means choosing appropriate analytical techniques that address both MRLs and achieve lower limits of quantification (LOQ) when dealing with banned toxic compounds.
Key learning objectives:
- Ultra-sensitive and can quantify more than 180 pharmacologically active vet drug compounds in three different food matrices down to 0.01 ug/kg for pork and chicken, 0.005 ug/kg for milk
- Mass accurate — rigorous detection with linear dynamic range up to 4 orders of magnitude, without a need of internal standards
- Precise and offers high specificity with the use of ion ratios.
