DeltaPlus XP with GasBench: |
Samples:
Headspace gases, whatever we can measure and you have a reference gas
available (within reason)
Air
Breath
CO2-water equilibration (0.3%CO2
in He available)
Carbonates (automatic phosphoric acid addition)
DIC (acidify, equilibrate, measure)
DOC (if you can oxidize it, you can try to measure
it) |
Sizes:
Standard 10-12 mL exetainer tubes used
Sample loop size, 100 uL; 10x dilution set up
50-200 ug Carbonate samples
500-700 uL samples for DIC
200-500 uL water sample for CO2-equilibration
|
Stuff:
GasBench II
Thermostated sample tray (26oC)
CTC Pal Autosampler
Acid Pump
0.3% CO2 in He for CO2-water
equilibration
Flushing needles
|
Availability:
Coordinate with TC/EA work
Hands on work required
Autosampler can be run without computer control,
e.g. flushing tubes.
Equilibration temperatures may change
