|
|
|
|
|
|
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

Netzsch/Picarro L2 130-i
|
Picarro L2 140-i
|
 |
 |
 |
|
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
|
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
