Sample preparation and separation can be performed using a sample cartridge (201). The cartridge includes a barrel (204) with a first and second end, a column segment (209) connected to the second end of the barrel, and a column (205) containing a sorbent material. The sorbent material includes particles that have antibodies attached to them to selectively retain analytes, proteins attached to them to retain certain classes of antibodies, or enzymes attached to them to perform specific modifications to certain classes of molecules. The column segment can be in thermal communication with a temperature control device in order to control the temperature of the column. |
