Marie Claire Perello
Sampling, laser micro granulometry, mechanical granulometry, material extraction chemical treatment of sediments, development and adaptation of analytical chain.
Instruments
Saw – grinding machine – lapidary lathe
- Production of thin blades in a range of sizes from 30×45 mm to 40×170 mm.
- Covered or polished, but also thick blades.
Laser diffraction microgranulometry
- Measuring range 0.020 – 2000 µm.
- Raw measurement, after decarbonation, destruction of organic matter, destruction of biogenic silica.
