Architectural Materials Analysis
SASAA
carries out routine analysis on a wide range of architectural paints and other
materials. Sample preparation, photography with low-power microscope and analysis,
and imaging with scanning electron microscope with energy dispersive analyser
(SEM-EDAX) is carried out to obtain information on composition and method of
application. We do not carry out analysis on binders and organic components
of paints.
In addition to undertaking full-scale projects, we offer a quick reference analytical facility (Q-RAF), with guaranteed delivery of report within two weeks of receipt of sample.
