Spare parts

O-rings and nets should be checked regularly for wear. Worn O-rings may not seal properly and over-used nets can affect distribution. Inspect the O-rings and evaluate the height equivalent to a theoretical plate (HETP) and peak asymmetry factor (As) to prevent poor performance due to old nets.


We recommend you to change the nets and O-rings when needed or at least annually. Please keep a set of each on your site, for code numbers refer to the table below.  


The column is delivered with O-rings in Ethylene propylene diene (EPDM). Ethylene propylene diene change characteristics when exposed to some organic chemicals. For repetitive long term use, use Fluoroethenepropene (FEP) polymers.
23 µm nets are supplied with the column and recommended for beads with an average particle diameter between 70-150 µm. For an average particle diameter < 70 µm use 10 µm or 12 µm nets and for an average particle diameter > 150 µm use 54 µm nets.

Troubleshooting

Find solutions to product related issues. For unlisted issues please contact local Cytiva service representation.

General advice to achieve good performance

Before packing or running the column please make sure that

  • the tubing, valves, gaskets etc. have the same inner diameter as the column in and outlets and tubing is not longer than needed.
  • the bed supports have a porosity appropriate for your chromatography medium.
  • the column has been correctly assembled, verified by passing a leakage test.
  • the chromatography medium and equipment are equilibrated in the packing buffer and to ambient temperature of packing environment.
  • that the pump is free from pulsations.
  • no pressure peaks appear.
  • that you have enough slurry volume, taken in account the compression factor of the medium.
  • packing is performed at optimal flow velocity.
  • the column meets pressure requirement for selected medium and packing procedure.

After completing the packing procedure please evaluate the efficiency of the column in terms of the height equivalent to a theoretical plate (HETP), reduced plate number (h) and the peak asymmetry factor (As).


Between batches it is recommended to perform cleaning-in-place (CIP) to remove precipitated material, strongly bound substances and other contaminants from the column bed without dismantling the column. Regular CIP is needed to ensure proper product quality and expected life time of medium and equipment.

Many issues that face chromatographers are common to all types of columns, while other issues are quite specific.
Select the appropriate equipment.

Worrying peak shape

Strange peaks

Column leakage

Poor reproducibility

Back pressure increases during operation

Unusual column appearance

Poor product recovery

Drifting baseline

Poor packing evaluation result

On this troubleshooting site, we refer to leading and tailing peaks as defined according to the following figures.


Leading peak

Tailing peak

 
Experience shows that the best method of expressing the efficiency of a packed column is in terms of its height equivalent to a theoretical plate (HETP), reduced plate number (h) and its peak asymmetry factor (As).
