Instrument List: | | |
Thermo MAT 253 and Kiel IV | VG SIRA | Nu Perspective/NuCarb |
| | |
Thermo MAT253 IRMS coupled to a Kiel Device for dual inlet measurement of δ18O and δ13C in foraminifera samples routinely down to 25ug in size | Sira with Multicarb for automated dual inlet measurement of carbonate samples for δ18O and δ13C | Nu Perspective with NuCarb automated prep system for δ18O, δ13C and clumped isotopes |
| | |
Thermo Delta V Adv./Gasbench | Thermo Delta V Adv./Gasbench | Thermo Delta V Plus and Costech |
| | |
Continuous flow measurement of acid digested bulk carbonate samples for δ18O and δ13C using the Thermo Delta V, Gasbench and CTC autosampler | Alternative use of the Thermo Gasbench for δ18O measurement in water by equilibration or δ13C of DIC in water samples | Costech EA combusting solid samples for simultaneous %N, %C, δ15N and δ13C analysis by continuous flow into the Thermo Delta V Plus |
| | |
Aerodyne QC-TILDAS | Netzsch/Picarro L2 130-i | Picarro L2 140-i |
| | |
Tunable infrared laser direct absorption spectroscopy with CO2 automated mixing manifold for δ18O, δ13C and Δ17O | Measures δD and δ18O of hydration water in minerals liberated by stepped heating | Picarro cavity ring down spectrometers to measure δD, δ18O, and δ17O of water |
| | |
Thermo Delta V Adv. with TCEA | Bruker/Netzsch | Coulometer |
| | |
Continuous flow analysis of oxygen isotope ratios with the Thermo TC/EA high temperature conversion elemental analyser | Measured evolved gases from solids using Fourier Transform Infrared spectroscopy | Weighed sediment samples are acidified on the AutoMate allowing the linked Coulometer to measure the carbonate (inorganic) carbon content |
Sedimentary Lab Instruments: | | |
Coulter Counter | Avaatech XRF Core Scanner | Sedigraph |
| | |
The Coulter Counter pulls sediment suspension through an aperture tube to count particles and measure size | The XRF Scanner allows rapid non-destructive measurement of elemental variation in unprocessed sediment cores | Sediment particles are allowed to settle. By using Stoke's law and an X-Ray beam particle size is measured |
Sample Preparation: | | |
WASP | Vacuum Furnace Line | Acid/Reference Gas Vacuum Line |
| | |
| Prep line for multi sample extraction of water from hydration minerals in to break-seal glass tubes | Prep line for sample cleaning by vacuum roasting prior to analysis | Glass vacuum line for the purification of orthophosphoric acid and manufacture of CO2 reference gas |
| | | |
Heated Gas Line | Microbalances | Wet Sieving |
| | |
Vacuum line for off-line preparation of break-seal glass CO2 gas samples for analysis and calibration | The microbalances allow for samples to be weighed in preparation for analysis. A small pump also allows foraminifera to be weighed with ease | A number of sieving stations means that cores can be processed quickly using sieves of varying dimensions depending on required further analysis |
|
New Wave Reserach Micromill |
| |
| A software controlled drill for automating accurate profiling of materials to produce a series of samples. Current used for profiling speleothems and shells. Also available is a manual Sherline drill for other applications |
