Laboratory Sample Preparation MARLAP 122 JULY 2004 for sample preparation to avoid sample loss and sample contamination. Due to the physical nature of the matrix, sample preparation for solids requires the most attention, and therefore is
SMART CUT™ LP is a Variable Speed Precision Polishing, Grinding, Lapping Machine. Designed for Mechanical Sample Preparation. SMART CUT™ LP Provides equal Precision, Productivity and Versatility as High Cost Fully Automatic Grinding/Polishing Machines, at a small fraction of the price.
The Choice of Grinding and Polishing consumables is a key factor that impacts the preparation process. Buehler's consumables are designed to improve efficiency and ensure repeatability with process. With a wide variety of products, there is a Buehler consumable .
Grinding is accomplished either through hand grinding or in a mechanical grinder. The effects of excessive grinding include lattice distortion and possible formation of an amorphous layer (Beilby layer) outside the grains.
The samples are comminuted by cutting and shearing forces, and the selected sieve cassette determines the final fineness. Various knife geometries and replaceable blades ensure maximum flexibility and durability. Cutting tools of various steel types as well as of hardmetal tungsten carbide can be used for controlling the abrasion problems.
