Clean Lab equipment and laboratory

Contact: Don Chipley

A class 100 clean laboratory is available in the geology department for preparation of samples for measurement by the Element HR-ICP-MS, Neptune MC-ICP-MS and the iCAP 6500 ICP-OES. The low detection limits of the Element and precision of isotope ratio measurements using the Neptune demand ultra-clean conditions during sample preparation to avoid contamination. Facilities include column chromatography for element separations and purification.

Thermo Scientific ELEMENT XR HR-ICP-MS

Thermo Scientific element xr lab equipment

The Thermo Scientific ELEMENT XR can resolve mass differences of 0.0001, which enables the analysis of elements such as: Li, B, K, Cl, Fe, As, Se, Au and others. Through the combination of a single Faraday collector with the SEM, the linear dynamic range of the Thermo Scientific ELEMENT XR has increased our dynamic range by three orders of magnitude, when compared to our ELEMENT. This instrument can be coupled with one of our two ESI-NWR Eximer 193nm ArF lasers for solid sampling or with our hydride generator for greater sensitivity of poorly ionized elements, such as Se, As, or Hg.

ThermoFinnigan Neptune MC-ICP-MS

ThermoFinnigan Neptune high resolution equipment

The Thermo Finnigan NEPTUNE high resolution MC-ICP-MS (multi-collector ICP-MS) is ideally suited for measurement of isotope ratios. The Neptune has high resolution capabilities so that interferences can be separated from analyte signals to ensure interference-free ratios. Samples can be measured as solutions or solids by laser ablation. Currently measured elements include: Sr, Pb, Sm, Nd, Hf, Cu, Zn, Li, B, Ca, Mg, Fe, Cr, U, Mo, Os and Re. U-Pb dating of zircon and other U-containing minerals is performed regularly.

Thermo Scientific iCAP instrumentThermo Scientific iCAPTM TQ ICP-MS

The iCAPTM TQs triple quadrupole inductively coupled plasma mass spectrometry (TQ ICP-MS) is a high-performance ICP-MS system with detection limits down to the single ppt (ng.mL-1) level. The TQ can operate in multiple modes (6 modes available) to resolve isobaric interferences (i.e. ArO on Fe, ArCl on As), thanks to its collision (kinetic energy discrimination )/reaction cell (mass shifting), and various speciality gas attachments (H2, He, O2 and and NH3). The PrepFast M5 autosampler with its automatic dilution feature enables reproducible and reliable dilution of samples and calibrations (up to 200x), as well as intelligent dilution, to ensure that all measured analytes remain within range of the calibration.

Thermo Scientific iCAPTM PRO ICP-OES

Thermo Scientific ICAP pro instrumentThe Thermo ScientificTM iCAPTM PRO inductively coupled plasma optical emission spectrometer (ICP-OES) is a compact bench-top ICP instrument that combines stable performance and economical operation. The duo design allows for radial and axial capabilities and has many additional features that provide benefits in terms of application flexibility and analytical productivity, such as with high matrix samples (i.e. high salinity solutions) or analyses of samples covering a wide range of concentrations, from ppb (ng.mL-1) up to several thousands of ppm (µg.mL-1). The high efficiency optical design enables simultaneous analysis of elements with detection limits at less than 1 ppb, spanning wavelengths from 167 to 852 nm. This instrument also features the PrepFast M5 auto-dilutor, offering similar features than our TQ-ICP-MS.

FEI-MLA Quanta 650 FEG-ESEM

FEI-MLS Quanta ESEM lab equipment

Our MLA 650 FEG ESEM is a high throughput field emission gun environmental scanning electron microscope. With its backscattered electron imaging capabilities and fast X-ray analysis, the MLA 650 FEG ESEM can be used to characterize geological and biological samples under low to high vacuum. The flexibility of the MLA 650 FEG ESEM is applicable to a wide variety of users.

The MLA 650 FEG ESEM has large specimen chamber, multiple high-speed energy dispersive X-ray spectrometers (EDS) and state of the art automated quantitative mineralogy software. Image and composition information can be acquired overnight from up to 16 samples without the need of operator assistance. The MLA software can identify minerals in polished sections of drill core, particulate or loose materials, and quantify a wide range of mineral characteristics, such as mineral abundance, grain size, and association - essential properties of samples. The MLA standards management system accommodates manual or automated standards collection, which makes the classification of spectra from new samples more efficient and reliable. This advanced standardization procedure is then used to classify spectra collected during the measurement.

SelFrag Lab

Selfrag lab equipment

The SelFrag is used to selectively fragment drill core samples into monominerallic components using high voltage electrical discharges of up to 200 kV. Currently, QFIR is one of only a handful of labs in World with this technology. Selective fragmentation has many advantages over traditional mechanical separation of minerals from whole rock samples, as it can liberate minerals with a high degree of selectivity, produce mineral fragments with clean surfaces, preserve the natural grain size distribution of the sample, and the process does not produce toxic dust.

Silicate Extraction Line

Silicate Extraction Line Stable Isotope LabSilicate Extraction Line Instrument Stable Isotope Lab

Oxygen isotope analyses of silicate and oxide minerals, and of whole rock samples are conducted using the BrF5 extraction method. Approximately 5 mg of finely ground sample are loaded into Ni reaction tubes and reacted with BrF5 at 575°C overnight. The extracted oxygen is converted to CO2 in contact with a heated graphite rod and the CO2 is then analysed off-line using a Finnigan MAT 252.
