|Material||Minimum sample size required|
|Forams (pre-extracted)||1 mg|
|Fish otoliths||1 mg|
|Shells & other carbonates||2 mg|
|Tufa (limestone)||2 mg|
|Samples must be ready for measurement (pH neutral, clean and dry).|
Radiocarbon dating carbonates – d13C and d18O measurements are included at no additional cost
