Instrument Details
IRMS & dual inlet
  • Faraday cups: including H/D collectors
  • Dual inlet: Equipped with a tube cracker (for 6 mm OD glass tube)
  • Intrumental precision

- d13C: 0.01 per mil (N = 80, based on certified CO2 standard gas)

- dD: 0.19 per mil (N = 80, based on certified H2 standard gas)

  • Analytical precision

- d13C: 0.6 per mil (N = 15, including the variation introduced from the vacuum line system for d13C-DIC)

GC & GC Isolink
  • Equipped with a Split and Splitless (SSL) injector
  • Equipped with an autosampler
  • Equipped with a pyrolysis reactor
  • Accuracy

- d13C: lipid, within 0.4 per mil (N = 18; based on alkane standards with known d13C values); gas, data coming soon (based on NaHCO3 standard with known d13C values)


- dD: lipid, data coming soon (based on alkane standards with known dD values)

  • Precision

- d13C: lipid, 0.15 per mil (N = 18; based on alkane standards with known d13C values); gas, data coming soon (based on NaHCO3 standard with known d13C values)


dD: lipid, data coming soon (based on alkane standards with known dD values)

EA
  • Equipped with an autosampler
  • Accuracy

- d13C: within 0.2 per mil (N = 20; based on standards with certified d13C values)

- d15N: within 0.12 per mil (N = 10; based on standards with certified d15N values)

  • Precision

d13C: 0.1 per mil (N = 20; based on standards with certified d13C values); 0.07 per mil (N = 10; based on working standard)

d15N: 0.16 per mil (N = 10; based on standards with certified d15N values); 0.3 per mil (N = 10; based on working standard)
