Laser Ablation IRMS Process

 

  • Sample sectioned into appropriate sizes for IsoScell sample chamber
  • IsoScell inserted into laser XYZ stage and target areas for sampling are identified.
  • Laser light used to ablate sample material into fine particles and gases.
  • These particles are then swept in an inert stream of carrier gas, (Helium) to the cryoflex interface.
  • The cryoflex interface converts sample material to CO2 via a combustion furnace. The CO2 is dried and then cryogenically trapped until all sample material has cleared the IsoScell sample chamber.
  • The trapped CO2 is released and focused on a GC column before eluting to the HS2022 IRMS.
  • The Isotope signal is measured via the IRMS and reported in the system results.
Step 1
Sample sectioned into appropriate sizes for IsoScell sample chamber
Step 2
IsoScell inserted into laser XYZ stage and target areas for sampling are identified.
Step 3
Laser light used to ablate sample material into fine particles and gases.
Step 4
These particles are then swept in an inert stream of carrier gas, (Helium) to the cryoflex interface.
Step 5
The cryoflex interface converts sample material to CO2 via a combustion furnace. The CO2 is dried and then cryogenically trapped until all sample material has cleared the IsoScell sample chamber.
Step 6
The trapped CO2 is released and focused on a GC column before eluting to the HS2022 IRMS.
Step 7
The Isotope signal is measured via the IRMS and reported in the system results.
