Abstract
Disclosed is a sample analyzer comprising: a sample measuring section including a detecting section for detecting a component contained in a sample and a flow path for feeding the sample to the detecting section; and a control section. The control section is programmed to automatically control the sample measuring section to flow a sample blank free of particles to the detecting section and detect a component contained in the sample blank to check a background of the detection after the sample measuring section performs washing of the flow path.
Claims21
A sample analyzer comprising:
- a sample measuring section including a detecting section for detecting a component contained in a sample and a flow path for feeding the sample to the detecting section;
- and
- a control section,
- wherein when measuring the sample, the sample measuring section feeds the sample to the detecting section through the flow path, detects the component contained in the sample with the detecting section, and then flows washing fluid to the flow path to perform washing of the flow path, and
- the control section is programmed to, after the sample measuring section performs the washing, automatically control the sample measuring section to flow a sample blank to the detecting section and detect a component contained in the sample blank to check a background of the detection.
A sample analyzer comprising:
- a sample measuring section including a flow path for feeding a sample, and a detecting section for detecting a component contained in the sample fed through the flow path;
- and
- a control section for controlling the sample measuring section based on a mode selected from a first mode for measuring a first type of sample and a second mode for measuring a second type of sample, the mode being selected by a user, wherein when the first mode or the second modes is set, the sample measuring section causes the flow path to feed the sample toward the detecting section and causes the detecting section to detect the component contained in the sample, and thereafter, causes the flow path to flow washing fluid,
- when the second mode is set, the control section causes the sample measuring section to automatically perform a background check for checking effect of the washing after the washing fluid is flown to the flow path, and
- when the first mode is set, the control section permits the measurement of a next sample with skipping the background check.
A method for controlling a sample analyzer by a computer, the method comprising the steps of:
- (a) flowing a sample to a detecting section of the sample analyzer through a flow path;
- (b) detecting a component contained in the sample with the detecting section;
- (c) flowing washing fluid to the flow path and the detecting section;
- (d) flowing a sample blank to the detecting section through the flow path;
- (e) detecting a component contained in the sample blank with the detecting section;
- and
- (f) outputting an alert indicating that a risk of carry-over is high if an amount of component detected in the steps (c) exceeds a predetermined threshold value,
- wherein the computer is programmed to automatically perform the steps (d), (e), and (f) after the step (c) is completed.
