|ProteCol™ C18 GP
|If you don’t need metal free column hardware, then the ProteCol™ GP HPLC column range is a robust, reliable alternative.
|ProteCol™-G C18 HQ203 and HQ303 for peptides
|ProteCol™-G C18 HQ203 and HQ 303 are columns packed with stationary phases of 200Å and 300Å pores, respectively. They both show reasonably fast diffusion rates for a typical peptide (MW~5000) or any other molecule of a similar size.
The difference between them is the specific surface area (surface area are per unit of weight) which in case of the 200Å pore size material is twice as high as for the 300Å pore size particles (200 and 100 m²/g respectively). The surface area is directly linked to the column capacity. Resolution and peak capacity both columns provide very similar results.
|ProteCol™-G C8 HQ1003 for proteins
|ProteCol™-G C8 HQ1003 – The protein separation column.
Since a 300Å pore size is not ideal for separating larger proteins, ProteCol™-G C8 HQ1003 column therefore uses a 1000Å pore size packing material.
Most proteins have a very hydrophobic core and they tend to unfold when coming in contact with a reversed phase surface. This can lead to very strong binding and sample loss. A C8 stationary phase gives much higher recoveries.
|ProteCol™-G C8 HQ125
|ProteCol™-P C18 HPH125 for High pH
|The ProteCol™-P C18 HPH125 column has a specially modified stationary phase which allows it to be used outside commonly recommended pH ranges. While the silica matrix material of any silica based HPLC column has a stability limit of ~pH8, the special C18 modification of the support in combination with the PEEK™-lined column hardware enables the column to be run at pH9 and above without deterioration of performance.
|ProteCol™-P C18 HQ100 extreme inertness
|Premium phase for optimal performance
SGE’s inert HPLC column range enables you to focus on your application rather than the column’s performance. The NIST SRM870 method is designed to provide an even bench mark for C18 column performance. ProteCol™-P C18 HQ105 approaches the ’ideal’ performance of a column with no non-specific interactions.
