the correct pH is one of the most important parameters in achieving satisfactory separation. Choice of ion exchanger. Begin with a strong exchanger (Q, S, SP) to enable development work to be performed over a broad pH range. Use a strong anion exchanger (Q) to bind the protein(s) of interest if their isoelectric point is
Quality by Design. Modern method development relies on a thorough evaluation of all possible experimental parameters, for example: • Buffer/Ionic strength. • Buffer pH Anion Exchange: Buffer A = 20 mM Tris, pH="8".0. Buffer B = 20 mM Tris, 1 M NaCl,. pH="8".0. Cation Exchange: Buffer A = 30 mM sodium acetate,. pH="4".5.
Thank you for purchasing a ZirChrom® HPLC column. Due to its unique characteristics—namely that its packing material is zirconia-based rather than silica-based, we strongly recommend that you read this guide before using your column. Method development with zirconia-based columns involves different steps than

Use the following table as a guideline to choose the appropriate SPE ion-exchange cartridge type for your particular analyte. Mixed-mode ion exchange chromatography combines the use of reversed-phase and ion-exchange modes into a single protocol on a single SPE cartridge. It can be used to isolate and separate

18 Sep 2013 Polar analytes are just that because they are ionic or exhibit strong dipoles – naturally interactive. • We're bringing them close to a polar surface and therefore can expect (should expect) other strong interactions to take place. • Strong dipole interactions (H- bonding) and ion-exchange are an integral and
25 Sep 2014 Abstract. An anion-exchange liquid chromatography method for the determination of heparin and its impurities (dermatan sulfate and oversulfated chondroitin sulfate) was developed using chemometric-assisted optimization, including multivariate experimental design and response surface methodology.
