Abstract
A method and apparatus for detecting improper liquid content of a metering tip of an analyzer. The method detects the content or status using radiation between 630 and 2000 nm, and comprises the steps of: a) aspirating the liquid into the tips; b) scanning the liquid; c) providing relative motion between the tip and the scanner while simultaneously scanning the liquid; d) detecting the amount of light transmitted to detector at all levels of the liquid; e) comparing the detected light with light known to be transmitted at levels of liquid free of air bubbles; and flagging the results.
