WebQuantitative LC-MS Guide, 1st Ed. 2013 Page 1 1 Introduction Mass spectrometry is a very sensitive technique and is widely regarded as having good selectivity. However, in many applications it is necessary to isolate the target analyte from what could be a sample containing thousands of other different molecules. Typically mass WebFor mass spectrometry (MS) applications with very polar compounds, HILIC (using an organic-rich mobile phase) provides a ten to twenty-fold sensitivity improvement. HILIC …
