About Us

OpAns was founded in 2004 by Kenneth C Lewis, PhD, and is currently owned and operated by Kenneth along with Tina Guilliams Baxter, both analytical chemists with extensive experience.

We are highly skilled and uniquely experienced at combining separation and mass spectrometry to quantify many analytes from a single sample.

We have developed multiple regulated (GLP, CLIA) assays where up to 50 analytes are quantified in a single injection.

Furthermore, we routinely perform these assays using small amounts of sample (e.g. 10 microliters of plasma or Dried Blood Spots).
