Each half of a split sediment core is wrapped in plastic to prevent drying and contamination. For long-term storage, we can shrink-wrap one half with a thick film that prevents moisture loss.

X-ray particle-size analysis of sediment settling rates
X-ray particle-size analysis of sediment settling ratesThe Micromeritics Sedigraph III uses X-rays to automatically analyze settling times for sediment sizes between 300 microns and 0.1 microns (2 phi to 13 phi).
