Faculty researchers at the Maryland Institute for Applied Environmental Health in the School of Public Health (SPH) and other departments in the UMD community analyze small molecules in a variety of natural products, environmental samples and human bio-samples. The identification and quantitation of trace contaminants in complex matrices, including food, air, water, soil and bio-fluids (blood, urine etc.) presents a formidable analytical challenge to exposure scientists and epidemiologists. The Core provides access to equipment that addresses these challenges, including an LC-MS/MS using triple quadrupole mass spectrometry, known as the gold standard in terms of sensitivity and accuracy.

The Core is located in the School of Public Health, Room 2131B.
- Agilent Instrument 6470 (LC-MS/MS): Agilent G6470CA Triple Quadrupole Mass Spectrometer
- Agilent HPLC System: G7120A 1300 bar UHPLC
The Agilent 6470 LC-MS/MS system is a bench-top triple quadrupole (QQQ) mass spectrometer capable of analyzing and quantitating very low-level trace compounds with extreme precision. It is designed to be coupled to a UHPLC system to provide compound separation prior to quantitation. Due to its ability to perform MS/MS analysis, the Agilent 6470 QQQ can obtain accurate quantitative information even in the presence of a high level of matrix interference. In addition, the MS/MS capabilities allow for the differentiation between compounds with the same molecular weight.
