About Us

We use cutting-edge metabolomics technology.

Liquid Chromatography Mass Spectrometry

Liquid Chromatography Mass Spectrometry (LC-MS/MS) is a proven technology which, to-date, has not yet been fully leveraged for clinical applications. Thanks to recent advances, LC-MS/MS is poised to become the method of choice for clinical testing, providing several key advantages over traditional methods:


Ultimate Specificity

LC-MS/MS can differentiate between variants of similar molecules, making it uniquely capable of avoiding false-positives and false-negatives.


Precise Selectivity

Because of its extreme accuracy, LC-MS/MS can focus in on precise molecules and compounds to provide exact results.


Extreme Sensitivity

LC-MS/MS can detect infinitesimally small amounts of materials, making it orders of magnitude more sensitive than traditional assays.


Increased Speed

With its ability to detect multiple variants of a compound in a single run, LC-MS/MS reduces the need to conduct multiple tests to hone in on a particular result.


Inherent Flexibility

A single LC-MS/MS machine can identify any compound, eliminating the need to have and maintain multiple specialized machines, as is the case with traditional methods.
