Ultra-Trace Chemistry Laboratory

TracechemlabThe Trace Chemistry Laboratory (TCL) was established in 1967 specifically to provide support for monitoring and assessing the impacts of the cloud seeding activities occurring in the State of Nevada. At that time, new and innovative trace chemical techniques were just beginning to be applied to such investigations around the world.

Today, DRI’s Trace Chemistry Laboratory is an EPA-certified trace metals lab and includes two state-of-the-art Thermo Finnigan Element2 High Resolution-Inductively Coupled Plasma-Mass Spectrometry (HR-ICP-MS) instruments complete with an autosampler for automated sample introduction. ICP-MS is a well-accepted technique for trace element concentration analysis. The instruments can operate in Low (LR), Medium (MR) and High (HR) resolution modes as needed for elimination of interferences and precise measurements. The instruments are optimized for long-term stability, excellent sensitivity, and high signal-to-noise ratio. The two HR-ICP-MS and an Elga 18.2 mega ohm ultra-pure water system are housed in a 300 sq. ft. class 100 clean room. The trace chemistry laboratory also includes a 200 sq. ft. cold lab (-15°C), a 400 sq. ft. wet chemistry lab and a 150 sq. ft. sample storage freezer (-20°C). DRI’s trace chemistry laboratory is dedicated to increasing the analytical capacity of water quality labs in developing countries through assessment of protocols and inter-laboratory comparisons.

Black carbon analyses are performed using an SP2, inter-cavity laser system.
