This page shows how to separate proteins and peptides with afﬁnity for metal ions by immobilized metal chelate afﬁnity chromatography using HiTrap Chelating HP, Chelating Sepharose Fast Flow,His MicroSpin Purification Module or HisTrap Kit from Cytiva.
Ultra-high performance liquid chromatographic (UHPLC) separation of ephedrine and its three structural analogs based on polar retention effect on graphite (PREG) mechanism using Supel™ Carbon LC column.
Ultra high-performance liquid chromatographic (UHPLC) separation of Vitamin D Metabolites― 3-epi-25-hydroxyvitamin D2 and 25-hydroxyvitamin D2, using Supel™ Carbon LC column with baseline separation, excellent peak shape, and sensitivity.
Ultra-high performance liquid chromatographic (UHPLC) separation of polar herbicides, paraquat and diquat using SupelTM Carbon LC column with baseline resolution, excellent peak shape, and good lot-to-lot reproducibility.
Developing an HPLC method for quantifying ephedrine HCl and pseudoephedrine HCl in traditional Chinese medicine (TCM) with a Discovery® C18 column to report: chromatographic data, linearity, specificity and repeatability, LOD and LOQ.
Capto MMC is a multimodal cation exchanger with the properties of a weak cation exchanger. In addition to electrostatic interactions, the ligand structure provides for additional interaction modes such as hydrophobic interaction, hydrogen bonding, and thiophilic interaction.
Desalting at laboratory scale is a well-proven, simple, and fast method that will rapidly remove low molecular weight contaminants at the same time as transferring the sample into the desired buffer in a single step.
