Abstract
A method for automated loading of liquid sample to a liquid chromatography testing device is provided including installing a disposable tip on a probe, moving the probe with an automated liquid handler to a loading position proximate to a sample, and drawing a sample into the disposable tip. The probe is then moved to an injection position proximate an injection port, and the sample is injected from the disposable tip into the injection port. Also provided are the novel injection ports. After injection of the sample, the disposable tip is then removed from the probe. These steps may be repeated a plurality of times to sequentially load a plurality of samples. An exemplary method of the invention is directed to use with a liquid chromatography apparatus. An apparatus for assisting in the removal of the disposable tip is also provided.
