OECD Testing Methods for Chemical Registration

Leeder Analytical offers a wide range of OECD test methods for the purpose of determining the physical and chemical properties of industrial chemicals. Several of the methods must be tailored to the specific chemical. This may require targeting specific potential pollutants or dealing with differences to chemical volatility or large molecular weight polymers. At Leeder Analytical we will review your project needs and develop the most appropriate and cost effective solution.

Sample Requirement

A representative sample of at least 500gm/ml is normally sufficient for most testing. The amount required will be dependent on the range of testing required. Some of the OECD methods currently offered include;

  • Melting point/range
  • Boiling point
  • Flash point
  • Water solubility
  • Partition coefficient
  • Density of liquids and solids
  • Particle size distribution
  • Respirable dust fraction
  • Hydrolysis as a function of pH
  • Sodium and calcium oxide content
  • Dissociation constant
  • Viscosity of liquids
  • Surface Tension of solutions
  • Ready Biodegradation
  • Inherent Biodegradability
  • Biodegradability in Seawater
  • Leaching in soil columns
  • Loss on ignition
  • Free water
  • Bulk composition
  • Burn rate
  • Combustibility
  • Transformation and dissolution of metals in aqueous media (GHS Annex 10)
