Mérieux NutriSciences offers a comprehensive set of tests suitable for evaluating the physical and chemical properties of technical products, active substances and formulated products. Our experts are equipped to perform a broad range of studies required for the registration of agrochemicals and plant protection products. All tests are performed in compliance with official (e.g. CIPAC, OECD) and internally validated methods.

Physical and chemical properties:

  • Spectral data (UV/Vis, FT-IR, NMR, MS, HRMS, XRD, etc.)
  • Melting point range and Boiling point range
  • pH – acidity or alkalinity
  • Relative density and bulk density
  • Surface tension
  • Water solubility and solubility in organic solvents
  • Partition coefficient (n-octanol/water)
  • Viscosity
  • Stability in organic solvents
  • Dissociation constant in aqueous medium
  • Physical/aggregate state, appearance, color, odor
  • Vapor pressure
  • Reactivity towards container material
  • Particle size distribution (granulometry)
  • Hydrolysis
  • Photolysis in aqueous medium
  • Accelerated and long-term (shelf life) stability studies
  • Thermal and air stability
  • Composition of smoke

Technical properties of formulated products:

  • Wettability
  • Suspensibility, spontaneity and dispersion stability
  • Wet & dry sieve analysis
  • Emulsifiability, re-emulsifiability and emulsion stability
  • Disintegration time
  • Particle size distribution, dust content, attrition, friability
  • Persistent foaming
  • Flowability / pourability / dustability
  • Burning rate / combustion completeness
  • Technical properties of aerosols (spraying pattern, clogging, etc)
