Stable Isotope Labelled Reference Materials
LC-MS can suffer from inherent and large quantitative uncertainty when applied to trace-level organics, but using stable isotope-labelled compounds internal standards (SILs) can improve the accuracy and precision of your analyses by enabling reliable recovery correction and compensating for matrix effects.
We offer an extensive portfolio of stable isotope labelled reference materials in 19 different test categories - ranging from nitrosamines to pesticides to VOCs - and invite you to select the most appropriate product to meet your needs.
