Elemental Scientific MicroMill Laser Ablation Device.

MicroMill is a microsampling device designed for high resolution milling to recover sample powder for chemical and isotopic analysis. The combination of submicron stage resolution and positional accuracy, real-time video observation and a custom designed software system allows for sampling of complex accretionary structures in skeletal and crystalline materials.

Higher sensitivity, improved stability, and less fractionation.

  • Complex crystal growth zonation: Subsampling provides high-resolution elemental isotopic chemistries and intra-zonal variations of the crystal structure
  • Accretionary growth structure examination: Subsampling within annual growth banding of molluscan shells allows reconstructing seasonal variations present during the life of an organism, such as a clam.
  • Precise sampling of growth zones in speleothems: determine seasonal changes by precise sampling in complex growth zone profiles.
  • Sampling from otoliths and bone: evaluate elemental and isotopic composition of bonelike materials through precise milling.
