SAMPLE PREPARATION IN PRACTICE

From size reduction of wool to sieving of limestone absorbents and optical particle analysis of catalysts – customers all over the world describe applications for which they are using RETSCH and Retsch Technology instruments:

• Standing On Safe Ground - Sample preparation of soils
  Alcontrol Laboratories, United Kingdom
• Tracking Down Fake Cashmere - DNA extraction from wool
  Fraunhofer Institut, Germany
• Quality Control of Limestone - Processing a 350 million years old raw material
  Schaefer Kalk, Germany
• Testing Vehicle Components - Preparation of plastic parts
  imat-uve, Germany
• Environmental Monitoring by Bio-Indicators - Sieving of soil samples
  Center for Marine Environmental Studies (CMES), Ehime University, Japan
• Catalysts for Improved Fuels - Fast particle measurement over a wide size range
  Shell Global Solutions, Netherlands

• 3D Sieving for Heavy Loads
  New sieve shaker AS 450 for sieve loads up to 20 kg
• Efficient Grinding at –196 °C
  The newly developed CryoMill is used for the cold grinding of materials which cannot be ground at room temperature or whose composition would be changed during the process
