Mass Spectrometry Allergen Testing

Mass Spectrometry Applications

If you are a food producer or regulator, you need specific and sensitive methods to detect allergens at trace levels. LC/MS/MS offers the unique advantages of multi-allergen screening, improved precision, and simplified sample preparation relative to other techniques, such as ELISAs.

Rapid, reproducible, multi allergen screening

Achieve sensitivities with LC/MS/MS that are equivalent to sensitivities of currently available ELISA kits, and improve reproducibility. The unique workflow provides MRM quantitative data as well as full scan MS/MS for spectral ID confirmation to minimize false positive results.

  • High sensitivity and specificity measures multiple allergens in a single run
  • High specificity provides highest accuracy and minimizes false positives
  • Workflow minimizes sample preparation
