Quantitative Analysis
We promise to support our clients with various organic/inorganic material R&Ds with utmost sincerity.
KOPTRI provides quantitative analysis service for various polymers utilizing GPC (Gel Permeation Chromatography).
Same as in quantitative analysis with GC and HPLC, we draw calibration plot with reference polymer and analyze the polymer sample with unknown content on GPC to calculate its polymer content based on peak area and the calibration plot. If you need help with analysis, please send us a request by submitting ‘Application Form’ under ‘Contact Us’ tab, and supervising researcher will aid you with a punctual and meticulous reply.
