Trap columns allow pre-concentration or desalting of a sample before injection onto the analytical column, while guard columns protect the analytical column from chemical and particulate contaminants
SGE Europe offers a comprehensive range of ProteCol trap and guard columns designed specifically for the needs of capillary liquid chromatography (LC), and has appointed Presearch to distribute the ProteCol range in the UK and Ireland.
The trap columns allow pre-concentration or the desalting of a sample before injection onto the analytical column.
The short, flexible design allows easy, efficient injector valve installation and the guard columns protect and maintain the integrity of the analytical column from the effects of chemical and particulate contaminants.
Chemical contaminants include any compound that affects the integrity of the stationary phase, or irreversibly binds to it.
ProteCol trap and guard capillary columns are designed so that the column body, column closure (screen), end fitting and the connecting tubing are all integrated into a single sealed unit.
This design eliminates dead volume and achieves optimal flow characteristics, thus minimising dispersion.
