Instrument List:


Thermo MAT 253 and Kiel IV


Thermo MAT 253-Kiel/Porapak trap

Kiel SIRA Clumped Kiel

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                                                                 

Thermo MAT253 with collector upgrade, Kiel Device and in-house built Porapak trap for automated routine 'clumped' isotope measurement




Thermo Delta V Adv./Gasbench

Thermo Delta V Adv./Gasbench

Thermo Delta V Plus and Costech


DIC Gasbench


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




Picarro L1 102-i

Netzsch/Picarro L2 130-i

Picarro L2 140-i

Picarro L1102 Netzsch Picarro Picarro 2

Picarro cavity ring down spectrometer to measure δD and δ18O of water

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



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





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:




Vacuum Furnace Line

Acid/Reference Gas Vacuum Line


Vacuum line

Gas line rig
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


Wet Sieving

Heated gas rig

Weighing room 250 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
