The surface analysis facility houses a full range of instrumentation used to determine surface area, particle size, pore size distribution and pore volume of porous solid materials as well as surface properties of liquids.
The trace metals analysis facility specializes in the determination of metals in samples of any form (liquid, solid) and type (environmental, geological, biological, synthetic). The facility features several Inductively Coupled Plasma Emission and Mass Spectrometers for elemental analysis. A full range of auxiliary equipment for the sample preparation is available such as microwave digestion systems, grinders and freeze dryers.
The wet chemistry facility is equipped with analytical instruments for detecting and measuring a wide range of organic and inorganic compounds. Typical matrices in this section include drinking water, processed water, wastewater, brine, and seawater. Segmented flow and other spectophotometric analyzers, total organic analyzer, ion chromatography, are used to characterize water matrices. CHNS-O elemental analyzers are used to characterize solid samples.
The molecular spectroscopy facility is equipped with analytical instruments for performing both qualitative and quantitative analysis of chemical materials based on the interaction of electromagnetic radiation with matter.
This section is equipped with several liquid and gas chromatography instruments connected to a range of selective and universal detectors for both qualitative and quantitative analysis. These chromatographic techniques are indispensable for the analysis of mixtures of organic compounds such as extracts from plants and microorganisms. Examples of detectors for the gas chromatographs are Flame Ionization Detector (FID), Thermal Conductivity Detector (TCD) and mass spectrometers. Our liquid chromatographs are equipped with ultraviolet and visible range detectors, refractive index detectors, and mass spectrometers.
Typical analyses in this section include the determination of accurate mass of small organic compounds using high resolution and high accuracy mass spectrometry. These analyses permit the determination of molecular formula of organic compounds as well as gaining insight into their structural makeup. Typical applications include metabolites analysis as well as tentative identification of unknown molecules. Our HRAMS instrumentations include a 9.4 Tesla Fourier Transform Ion Cyclotron Resonance (FT-ICR) mass spectrometer and an Orbitrap mass spectrometer, both have mass accuracies better than 2 ppm and are equipped with different ionization sources. Other instrumentations in this unit include MALDI-TOF and an ESI-QTOF.
Beyond simple trace metal analysis, this lab unit focuses on the speciation of mercury and arsenic. The primary instruments for this purpose are triple quadrupole inductively coupled plasma mass spectrometers equipped with high performance liquid chromatographs. Emerging organic contaminants analysis is performed using gas chromatographs with triple quadrupole mass analyzers. The lab is equipped with a high level of automation for sample extraction by accelerated solvent extraction, sample clean up via gel permeation chromatography coupled to automated sample concentration.
