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.

Abstract: A controller controls a sequence of actions at a device. The controller includes computer instructions that receive a plurality of user inputs and command information associated with an action for the device to perform. The first user input defines a target in a bed layout of the device. The second user input assigns the target to a first zone of the bed layout. The third user input assigns the target to a second zone of the bed layout. The fourth user input indicates an operational mode for controlling performance of the action. The operational mode includes a non-validation mode defining a state of operation wherein a device limitation is not imposed to restrict the action. The command information includes a command name identifying the action and a device identifier.
