A liquid chromatography system comprises a chromatographic disc (4) for resolving molecules in a liquid sample, a sample loader (2) adapted to house the disc (4), the loader (2) having one or more storage channels (16) for taking up a predetermined volume of the sample by capillary action and delivering it to the disc (4) and means (18) for delivering a buffer and/or eluent to the disc. The sample loader (2) may comprise a body portion (6) acting as a housing for the disc (4), and having (i) a loading channel (8) for conducting liquid onto or through the disc (4), comprising an afferent portion having an inlet (10) for conducting liquid to the disc (4) and an afferent portion having an outlet (12) for conducting liquid away from the disc, and (ii) a selector element (14) (e.g. a rotatable disc or a slideable bar) movably mounted on the body portion (6) so as to break the afferent portion of the loading channel (8). |
