What's Happening

THE WATER QUALITY CENTRE IS CURRENTLY OPEN AND OPERATING UNDER PROVINCIAL COVID-19 GUIDELINES.

Congratulations to Kristen Yeh, M.Sc. student in the EnLS graduate program, her supervisors and the WQC's Naomi Stock on their publication, which was recently featured on the front cover of the journal, Forensic Chemistry.

All three studies used the WQC's Bruker SolariX-XR FT-ICR. The Bruker SolariX XR (eXtreme Resolution) is a Fourier Transform – Ion Cyclonic Resonance (FT-ICR) mass spectrometer equipped with a 7 T magnet. This instrument is capable of up to 10 million resolution and allows the user to access chemical information, including isotopic fine structure and mass accuracy (< 100 ppb) that was previously inaccessible. A wide variety of applications is possible including complex environmental sample and petroleum product analyses, proteomics studies and metabolomics research.

Congratulations to Lan Ma and Wei Wang, Ph.D. graduates of the EnLS graduate program, and their co-authors on their publication, which was featured on the front cover of Environmental Science and Technology.

The analyses were carried out using two of the WQC's ICP-MSs, the Nu Plasma2 multicollector ICP-MS and the Agilent 8800 triple quadrupole ICP-MS.
