Carbonates δ13C+ δ18O analysis
Carbonate samples must be ground, homogenized and well dried. They can be sent in
eppendorf tubes, cetrifuge tubes or any other leak proof vessel. If shipping in glass
vials be sure they are packaged properly. SIF is not responsible for breakage during
shipment.
Required sample size: 50 to 400ug of carbonate in sample
Gas δ13C + δ18O analysis
Samples should be submitted in airtight 12 ml Labco vials. Ensure they are packaged
properly if samples are being shipped. SIF is not responsible for breakage during
shipment.
Required sample size: CO2 conc. within 400 to 8000 ppm range
Water, dissolved inorganic carbon(DIC) δ13C analysis
DIC samples must be shipped and submitted in air tight vials with no head space. To
avoid leakage during transport you should wrap parafilm around the lid of the vial.
Vials should be properly packaged to avoid breakage during shipment. SIF is not responsible
