HPLC's strength lies in its versatility, sensitivity, and selectivity. This chromatographic technique uses different mobile phases and columns to achieve the necessary separation of polar, thermally labile, non-volatile and other analytes that cannot be analyzed by gas chromatography. HPLC is non-destructive and analytes can be isolated for further spectroscopic analysis. Very low detection levels are achievable and multiple detectors can be used in series to monitor specific analytes. A wide variety of detectors are used in this laboratory to determine electrochemically active compounds, high molecular weight analytes, and non-UV absorbing materials.

• Quantification and identification of inhibitors and other electrochemically active components in products.
• Trace analysis of polymeric extracts
• Characterization of isocyanates, sulfonic acids, biocides, and peroxides through the application of derivatization techniques, ion pairing, normal and reversed-phase HPLC.
• Quantification of glycols at low levels in aqueous systems using pulsed-mode amperometry (PAD).
• Isolation of specific analytes for further spectroscopic analysis and use of preparative LC columns permits simultaneous analysis and trapping.
