Elemental Analysis of Diatom Cell walls using a FIB-SEM-TOF-SIMS

文档简介Diatoms are worldwide abundant unicellular microalgae (Fig.1). Their fossilized remains are the main component of diatomite, a mineral widely utilized in many differentindustries as an absorbent or additive. The chemical composition of the shells is critical for the properties of the final product. Therefore, there is a huge need to analyze the elemental distribution in the original diatoms.
