Humic acid - Import export

For GPC / SEC analysis in DMSO, examples: - amylose, amylopectin, starch - urea-formaldehyd resins (UF-resins) - melamin-urea-formaldehyd resins (MUF-resins) - lignins, humic substances, humic acids, coniferous wood bark essences - polysaccharide, polysaccharid derivatives - poly(N-isopropylacrylamid) PNIPA - poly-vinylpyridin - calibration: pullulan, dextran, polyvinylpyridin et al. Advantages - optimized for DMSO-GPC applications - interactionfree pure GPC/SEC - easy, reliable and robust GPC/SEC-calibration by dextrans, pullulans et al. - low column bleeding for low detectornoise for improved lightscattering or viscosity detection - 12μ particle technology for low backpressure - large porevolume and optimized mass transfer for polymers giving optimized resolution - low costs caused by long livetime of column – result of combination of optimized proprietary particle and packingtechnology.
