Similar to the principles of thin-layer chromatography, gas chromatography, and high-performance liquid chromatography, column chromatography separates compounds based on the differences in adsorption, dissolution, and partition coefficient of the compounds in the stationary and mobile phases (SPs and MPs)...
4.1.3 Ion exchange chromatography (IEC) IEC is a technological process that separates ions and polar molecules based on their affinities to an ion exchanger. Ingredients can be selectively separated based on their charges through the choice of different columns, by altering the pH of eluents, or...

2. Visibility: When the PFA transparent cylinder separates the color sample, the separation color band can be seen intuitively 3. Sieve plate: Sieve plate with various particle sizes can be provided, with excellent distribution effect and better separation 4. Larg...
Liquid Chromatography Column Separates GlycansMelanie Sena
In this study, we have separated a model therapeutic antibody into three fractions according to the composition of the N-glycan by using a novel FcγRIIIa chromatography column. Notably, Fc galactosylation was a major factor influencing the affinity of IgG-Fc to the FcγRIIIa immobilized on...
Reversed-Phase and Hydrophilic Interaction Phases Combined on a Single Column The Acclaim®Mixed-Mode HILIC-1 column utilizes a unique silica-based, mixed-mode stationary phase that combines both reversed-phase (RP) and hydrophilic interaction liquid chromatography (HILIC) properties. The column functi...
A new cation-exchange microcolumn employing a borate buffer reportedly separates hemoglobin A1c from other labile glycosylated intermediates in a one step procedure. The effect of commonly occurring abnormal hemoglobins on the hemoglobin A1c (Hb A1c) levels as determined by this new technique has been...
8. Turn on the power to the column compartment. 9. Configure the column switching valve in the chromatography data system: a) In the Instrument Configuration Manager dialog box, select the position (Upper Valve, Lower Valve). b) Select the valve model. 10. Switch the valve into the ...
