Biogenic Apatite (CaPO4) Isotope Analysis – Sample Types and Selection

The following recommendations are general guidelines. Individual sample size requirements largely vary based on the preservation of the material and concentration of phosphate therein. Contact us for advice if you are concerned that your samples are too small.

Reminders

DO NOT wrap samples in aluminum or any metal foil. Use weighing paper if you need to wrap them.

Submit samples in a ziplock bag or teflon container with PRINTED SAMPLE ID attached outside the bag.

Always choose the best samples for your research objectives

Our recommended sample sizes assume the material is dry and free of adhering matrix.
