the parameters used in this video such as the size of the xk chromatography column type of resin packing volume and flow rate are examples in actual operation please follow the experimental requirements and the resin instructions estimate the amount of slurry needed based on the final volume of the column most of our resins are delivered in a slurry concentration of 75 percent in storage solution in most cases 20 ethanol to calculate the slurry volume needed to pack a column at a certain volume the following equation can be used for example to pack a 120 milliliter column with a resin that has a slurry concentration of 75 percent and with compression factor of 1.15 the necessary slurry volume will be 184 milliliters the compression factor is often found in the instruction for the resin if not available use a compression factor of 1.15 ensure that the resin is washed thoroughly into the packing solution before packing is started use a fritted glass funnel to wash the resin over to the

What are the different types of columns used in chromatography?

Two types of columns are used in gas chromatography: packed columns and capillary columns.

What are the different types of column packing in chromatography?

Currently, there are three different ways to pack process chromatography columns: flow pack, which uses constant pressure or flow; dynamic axial compression, achieved by axially compressing the media slurry; and pack-in-place, which incorporates column valves into the flow cells.

What is column in protein purification?

Hydrophobic proteins and hydrophilic proteins can be separated by column chromatography. In this method, a column is packed with small beads that are coated with a material (a resin) that attracts hydrophobic amino acids, and the mixture of proteins is dissolved and passed over the beads.

What are the different types of columns for purification?

The four major types of column chromatography include affinity chromatography, ion exchange chromatography (IEX), hydrophobic interaction chromatography (HIC), and size exclusion chromatography (SEC).

Which columns are suitable for sample purification?

Liquid chromatography columns, or LC columns, have been used in the food, chemical, petrochemical, and pharmaceutical industries and forensic, clinical, and medical determinations for sample purification and analysis.

How do you calculate column packing?

The PF varies in relation to bed height and is calculated as y = 0.002x + 1.22 (where y is the calculated PF and x the packed bed height). For each bed height, the acceptable interval for the packing factor is 0.03.

Which different types of columns can be used in HPLC?

Four Types of HPLC Columns: Normal Phase Column. Reverse Phase Column. Ion-exchange Column. Size Exclusion Column.

What is packing a column?

A packed column contains particles that either constitute or support the stationary phase, and the mobile phase flows through the channels of the interstitial spaces. Theory has shown that performance is enhanced if very small particles are used, which simultaneously ensures the additional desired feature that
