Sample Analysis

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, SEM, Instron, Viscometer...

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.
• Organic compound analysis

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.
