Abstract
A sample pre-separation and concentration system for detecting low levels of analytes in highly complex mixtures includes a plurality of trapping columns having a high selectivity for classes of compounds of interest, upstream of a standard separation column. The system may be used, for example, to measure urinary 8 hydroxy 2′ deoxyguanoisine.
Claims8
A high pressure resistant electrochemical flow column comprising a porous core material, surrounded by a plastic sleeve with plastic fittings touching the core at the ends of the sleeve, with said plastic sleeve, said plastic fittings and said porous core being inserted into a reinforcing metal sleeve and capped with caps on and surrounding the ends of said metal sleeve, said reinforcing metal sleeve, said plastic fittings and said plastic sleeve being sealed together by mismatched thermal rates of expansion, and at least one electrode communicating with said porous core material.
