Environmental Engineering Reference
In-Depth Information
Thermal
analysis
DSC and TGA
Determining the effect of heating on
polymers in terms of glass transition,
and melting temperature. Measures
heat low associated with oxidation
and change in crystallinity
MW
GPC and GC-MS
Loss of molecular mass of the
polymer - this is dificult to do with
an environmental sample, because of
the presence of contaminants such as
salts and so on, that add complexity
to the analysis
Respirometry Respirometer
Measure consumption of oxygen or
production of carbon dioxide
Electrical
properties
EIS
Determination of electrochemical
properties of polymers. Monitors
the integrity of the oxide layers on
surfaces
