C⏣mplex Chemical C⏣mp⏣siti⏣n Analysis Lab (C³AL)

We are a research group in the Department of Chemistry and Biochemistry at California State University, Los Angeles. Our research revolves around the characterization of complex chemical mixtures via state-of-the-art techniques, including two-dimensional gas chromatography and high-resolution mass spectrometry. Our ultimate objective is to gain a fundamental understanding of how the chemical composition influences the properties of complex chemical mixtures at the molecular level. Additionally, we specialize in the analysis of microplastics, which is an emerging field with important environmental implications. Through our work, we strive to make a positive impact on society by contributing to the development of sustainable solutions.

First-of-its-kind strategic plan looks to reduce, prevent microplastic pollution

“It can penetrate through the blood vessels. It has been found in the brain,” said Petr Vozka, a biochemistry assistant professor at California State University, Los Angeles.
