The Centre for Cold Regions and Water Science (CCRWS) is a collaborative research facility that houses four research centres/groups and a variety of state-of-the-art analytical equipment. The facility, which opened in 2013, is funded by Laurier, the Government of the Northwest Territories (GNWT), the Canada Foundation for Innovation (CFI), the Ontario Ministry of Research and Innovation (MRI), and the Federal Economic Development Agency for Southern Ontario (FedDev Ontario).
The CCRWS is home to two interdisciplinary Laurier research centres and two collaborative research groups.
The CCRWS analytical equipment is available to internal and external users. Access policies and fees may vary by user type – for details, contact Gena Braun. User types are defined as follows:
The Faculty of Science research instrumentation technicians will provide initial training for all new internal or external users preceding first use. New users cannot be given initial training by other users or students. Contact Gena Braun to schedule training.
Following training, users can reserve the analytical equipment online using the booking calendar.
User fees have been created to offset the costs of instrument operation and maintenance. Contact Gena Braun for the current fee schedule.
The AutoAnalyzer can test for phosphate and ammonia using continuous flow colorimetry. It is equipped with a 120-vial autosampler, a high-precision pump, two manifolds, and a digital colorimeter with detection limits reaching 0.2 mg/L. The internal diameter of the glassware is 2 mm, which allows complex and non-homogeneous samples to be run without clogging. Roughly 50 samples can be run per hour with a minimum volume of 3 ml.
Using the Pregl-Dumas combustion method, the elemental analyzer can determine the weight percent carbon, hydrogen, nitrogen, or sulphur in a variety of sample types, with an analytical range of 0.001 to 3.6 mgs (element dependant). The 60 position autosampler allows for automated analysis, and the data is collected by the data management software.
The PinAAcle spectrometer allows for both flame and transversely-heated graphite furnace atomization, enabling the analysis of a wide range of sample concentrations. The furnace camera simplifies pyrolysis method development. This system is currently equipped with lamps for Ag, Al, Ca, Cd, Cu, Fe, Hg, K, Mg, Na, Ni, Pb, Rb, Ti, and Zn.
The Optima 8000 ICP-OES is a dual-view instrument, allowing for determination of both high and low concentrations in the same method. Use of compressed air as a shear gas removes the plasma tail plume, which eliminates many interferences and minimizes the need for the addition of ionization suppressants. The photons generated within the plasma are measured by a charge-coupled device (CCD) array detector.
This ICP can measure almost all of the elements in the periodic table, sequentially, within a single sample. The dynamic range of measurement is element and matrix dependent, but typically ranges from tens of ppb (mg/L) to hundreds of ppm (mg/L).
The Mantech AssayPlus system is an automated multi-parameter ion-analysis system. It has a TitraSip module and a 73 position autosampler that holds 50-ml tubes. The system is currently equipped with ion selective electrodes for the analysis of ammonia, copper, chloride, lead, nitrate, potassium, and sodium. The system is controlled by PC Titrate software.
The Centre for Cold Regions and Water Science boasts a large rooftop greenhouse. Contact Gena Braun for greenhouse policies.
The Shimadzu can be used to analyze a variety of carbon species and total nitrogen (TN) in liquid or solid samples using catalytic oxidation. Carbon can be assessed as total carbon (TC), total organic carbon (TOC), non-purgable organic carbon (NPOC), and inorganic carbon (IC). This instrument is equipped with an ASI-L autosampler.
The energy dispersive x-ray fluorescence spectrometer is used to determine the concentration of elements from sodium to americium in a wide variety of sample types. It performs non-destructive analysis with parts per million (ppm) level detection limits. The sample turntable holds 10 samples with diameters from 25 to 52 mm.
