Isotope Ratio Mass Spectrometer

Gas Bench (GB):  working in Continues Flow with Delta V plus

• δ13C and δ18O in carbonates
• δ13C(DIC), δ18O, and δD in water

Elemental Analyzer (EA):  working in Continues Flow with Delta V plus

• δ13C, δ15N, and δ18O in sediments (excluding silicate fractions)

Kiel Carbonate (KC):  working in Dual Inlet with MAT 253 plus

• δ13C and δ18O in carbonates for very small amount of sample(i.e. forums)

Laser Fluorination (LF):  working in Dual Inlet with MAT 253 plus

• δ18O in silicate fractions

Gas Bench (GB):

• δ13C and δ18O in carbonates
  Pure Carbonates fine powered samples are required
• δ13C(DIC) , δ18O, and δD in water
  Filtered (using nylon filter), and unfiltered samples can be analyzed

Elemental Analyzer (EA):

• δ13C in bulk (inorganic + organic), δ18O in bulk and δ15N
  Fine powder samples are required
  For δ18O, remove silicate fractions also
• δ13C and δ18O in organic fractions
  De-carbonated fine powder samples are required

Kiel Carbonate (KC):   For high Isotope Precision in small amount of carbonates such as forums, enamel etc.

• Pure carbonate and cleaned powered samples are required.
• Forums must be cleaned without powered

Laser Fluorination (LF):  silicate fractions

• Individual silicate mineral must be separated from the rocks using magnetic, gravity, and density separation techniques.
• Separated diatoms, and radiolarians can also be analysed.

Samples must be stored in air tight vials. Samples must be prepared by the user for any type of analysis as describe above before sending to the lab.
