Optical analysis
The LEREM is equiped with an optical microscope that allows him to carry out expertises on packaging and determines the causes of some problems that could have manufacturers or users.
- Lacquer analysis by means of Fourier Transform Infra Red spectroscopy
- Searching for water traces in non aqueous products using the Karl Fisher method
- Measurement of varied physico-chemical characteristics (pH, tin content, viscosity, flash point…)
- Various vapour-phase chromatographic analyses (catharometer or flame ionization)
Determination of the packaging pressure resistance of various materials (glass or plastic packaging…).
