SGS is a leader in preparing a wide range of materials for chemical analysis.

Technicians in our laboratories follow industry best practices to ensure that all samples are prepared appropriately to give reliable analytical results.

Many sub-samples must be pulverized to a pulp as a final sample preparation step before chemical analysis.  SGS laboratory staff ensure that your sample is pulverized to an acceptable particle size (usually <75µ), and is free of contaminants. They select appropriate mills, bowl types, cleaning and sealing procedures to provide you with the best possible results. Our sample pulverizing services include:

  • Pulverize 250g in a chrome steel ring and puck mill so that 85% passes through a 75µ screen
  • Pulverize 500g in a chrome steel ring and puck mill so that 85% passes through a 75µ screen
  • Pulverize 1.2kg in a chrome steel ring and puck mill so that 85% passes through a 75µ screen
  • Pulverize 3.0 kg in a chrome steel ring and puck mill so that 85% passes through a 75µ screen
  • Pulverize 500g to 1.2kg in a mild steel ring and puck mill so that 85% passes through 75µ screen
  • Pulverize 100g in an agate ring and puck mill so that 85% passes through a 75µ screen
