The UCLA Pasarow Mass Spectrometry Laboratory (PMSL) is a multidisciplinary research environment dedicated to advancing molecular science through integrated mass spectrometry and innovative analytical approaches. The laboratory brings together a diverse group of researchers committed to scientific discovery, collaborative research, and the training of students across disciplines.

Supported by NSF and NIH shared instrumentation programs, PMSL houses a comprehensive suite of state-of-the-art mass spectrometry platforms. The facility integrates gas and liquid chromatography with multiple ionization methods—including electron ionization (EI), chemical ionization (CI), electrospray ionization (ESI), and laser desorption (LD)—enabling broad analytical capabilities within a single, unified laboratory environment.

Our research focuses on the characterization of molecular structure and abundance across a wide range of analytes, including proteins, metabolites, lipids, and complex molecular systems. By combining complementary mass spectrometric techniques, PMSL supports multi-omics investigations and interdisciplinary applications spanning biological, chemical, and material sciences.
