Ultra-Clean Trace Elements Laboratory (UCTEL+)

The Ultra-Clean Trace Elements Laboratory (UCTEL; pronounced as “you-see-(and)-tell”) is an ultra-trace analytical laboratory dedicated to the study of environmental chemistry and biogeochemistry of trace elements. Originally constructed in the Parker Building in 2003, the lab was upgraded and moved to the Wallace Building in March 2013 and is now known as UCTEL+. A portable node of UCTEL+, known as PILMS (Portable In-situ Laboratory for Metal Speciation), has been operating aboard the CCGS Amundsen since 2007.


UCTEL+ is a metal-free, Class 100 cleanroom laboratory with a Class 10 enclosure. All the lab counters and fume hoods are made of polypropylene. The temperature is controlled at 20 oC, and the relative humidity is controlled at 40%. Major instruments including HPLC (Waters 626, Agilent 1200), ICP-MS (PerkinElemer DRC II), ESI-QQQ-MS (Agilent), a mercury analyzer (Tekran 2600), a methylmercury analyzer (Brooks Rand MERX), as well as an ultra-pure water purification system (Milli-Q Element).


Led by Dr. Feiyue Wang, UCTEL+ (and its predecessor UCTEL) has been involved in numerous major research networks and projects including the ArcticNet Network of Centers of Excellence, GEOTRACES, the Circumpolar Flaw Lead System Study (CFL), the Northern Contaminants Program (NCP), the Collaborative Mercury Research Network (COMERN), the Metals in the Environment Research Network (MITE-RN), and the Metals in the Human Environment Research Network (MITHE-RN).


As one of the most advanced ultra-trace analytical facilities in Canada, UCTEL also welcomes external users and samples, provided that the cleanroom protocols are strictly followed.


UCTEL was funded by Canada Foundation for Innovation (2001, 2006). The construction and upgrade of the new lab UCTEL+ was made possible as part of the Canada Excellence Research Chair (CERC) program.
