Obstruction detection circuit for sample probe. |
摘要 |
An obstruction detection circuit for detecting an obstruction of a sample probe of an automated sample aspiration/dispensation device and a method for detecting such an obstruction. In one embodiment the obstruction detection circuit includes a pressure sensor measuring the pressure in a fluid conduit connecting a pump and the sample probe orifice. The pressure within the connecting fluid conduit is measured by the pressure sensor shortly after the start of the aspiration or dispensation of a fluid volume by the automated sample aspiration/dispensation device. The pressure within the connecting fluid conduit is again measured after the completion of the aspiration or dispensation, and if the pressure has not returned to a predetermined range within a predetermined amount of time, an error condition is reported. <IMAGE> |
