Make your MS analysis quantitative without standard substances.

Let’s quantify everything!

Challenge

In LC/MS the trend is towards collecting as much data as possible – e.g. in drug metabolism or environmental screening.

The most accurate way is to use isotopically labelled standard substances. If these are commercially available, they are expensive.

  • Available isotopically labelled standards are expensive.
  • Standards are not available for most of the substances.
  • Synthesising a standard in-house is time-consuming and tedious.
  • Using structrally similar compounds leads to misleading results – using positional isotope may lead to a misestimation of concentration of 40 times.
Solution

To quantify with Quantem you only need your computer, structure of the compound, MS signal and used gradient program.

To make the concentration prediction specific to your method and instrument, the same information for at least 5 compounds with a known concentration is needed. The latter can be internal standards, quality control samples or analytes quantified with standard substances.

Samples

Pharmaceutical byproducts, important metabolites, environmental contaminants, etc.
