Ordering Numbers

The table below will enable you to “read” your part numbers and confirm that a part number you are about to use for ordering is exactly what you need. This should reduce ordering errors that can delay delivery of the correct column or product.

Please do not use this table to write your own part numbers. Certain attributes that are available in some stationary phases are not available in others. If you are unsure of a part number please use our ordering number generator or contact us directly to confirm availability.

Gel code & hardware code

The part numbers are composed of a gel code, which describes the packing in the HPLC column and the hardware code, which describes the column itself. The gel and hardware codes are further divided into short codes that describe the chemistry, pore size, particle shape, particle size, column length and column inner diameter. These are followed by fitting codes for internal use. The system is set out schematically below:

Gel code				Hardware code
Chemistry code	Pore size in nm	Particle shape	Particle size in µm	Length in mm	Inner diameter in mm
Example: An analytical column with the part number “AS12S052546WT” is in your stock. “Read” the part number as AS / 12 / S / 05 / 25 / 46 and you can determine that this column is:
Pro C18	12 nm pore size	spherical media	5 µm particle size	250 mm length	4.6 mm i.d.
