CM-Tec
Sample Testing
Characterization
By using GPC, HPLC, TLC, IC, FTIR, UV-Vis, NMR, GC, LC-MS, AAS, ICP-OES, we are able to
help our clients in analysis and identification on polymer, organic, and inorganic samples. On
the other hand, physical properties of sample materials, such as Tg, decomposition
temperature, crystal structure, morphology, mechanical strength, surface area, etc., can be
analyzed through the use of DSC, TGA, XRD, SEM, Instron, Viscometer, BET......
With our well equipped labs, we provide a broad range of analytical services. Up to date, the
analytical services that we have performed for our customers are:
• polymer sample analysis:
Hydrophobic polymers - polymethacrylates, polyvinyl acetate, polystyrene, polyurethane,
fluorescent dye-tagged polystyrene, polyvinyl pyridine-co-styrene, polyphosphazenes, etc.
Hydrophilic or amphiphilic polymers - polyvinyl alcohol, polyacrylic acid, polyethylene glycol,
polyacrylamide-co-acrylic acid, polyvinyl pyrrolidone, amphipathic polyvinyl ether, fluorescent
polymer, cellulose polymers, etc.
• elemental analysis: drug Inorganic fillers, organic or inorganic additives, etc.
• pharmaceutical product analysis: API intermediates, etc.
Our GPC systems are the most frequently used equipment in our sample testing services. We
are very expert at the polymer analysis via using GPC systems. There are several GPC
systems in our labs used for testing hydrophobic and hydrophilic or amphiphilic polymers
respectively. Various hydrophobic solvents and aqueous solvent solutions are used for
different polymers testing on GPC. We not only select best-fitting solvents for hydrophobic
polymer analysis, but also optimize the aqueous solvent solutions for hydrophilic or
amphiphilic polymer tests. Generally, it is more complicated to analyze hydrophilic or
amphiphilic polymers. The aqueous solvent solutions have to be adjusted carefully to fit
different polymers with cationic, anionic, non-ionic or neutral features.
