Small Molecule LC-MS/MS Services

SHARE

IDEXX BioAnalytics now provides high quality LC-MS/MS bioanalysis for small molecule compounds. In addition to standard protein precipitation, IDEXX BioAnalytics offers solid phase extraction and solid supported liquid extraction. We offer the same high-quality, flexible, and fast turnaround in our bioanalysis laboratory as we do for our current clinical and anatomic pathology services.
