ANALYTICAL INSTRUMENT PROVIDING CORRECTED SAMPLE VOLUME DEPENDENT PARAMETER
First Claim
1. An analytical instrument for operative connection to a disposable sample measuring and diluting device having at least one measuring cavity for extraction of a defined volume from a larger volume of a liquid sample, the instrument comprising:
- a measuring unit adapted to measure a sample volume dependent sample parameter;
electronics adapted to process signals from the measuring unit;
an input unit adapted to receive data directly or indirectly related to an established volume value of the at least one measuring cavity of the disposable device, from an information carrier applied to or distributed with the disposable device; and
a correction arrangement adapted to compensate differences in the established volume value of the at least one measuring cavity of the disposable device to obtain a corrected sample volume dependent sample parameter, when the disposable device is used on the instrument.

Abstract
The invention provides a device for extraction of a defined sample volume from a larger sample volume. The device includes a body having a reference surface and a measuring cavity extending from a part of the reference surface into the body, thereby forming at least one opening plane substantially uniform with the reference surface. An information carrier is applied to or distributed with the device, having direct or indirect volume information about defined volume established for the cavity. The invention also relates to a method for determining the volume of such a cavity, to a set of at least two such devices, to a method for dilution of at least two liquid samples by using at least two such devices, to an analytic instrument, to a method for operating such an instrument, to a system including the device and the instrument, and to a method for operating the system.

8. A method for operating an analytical instrument with a disposable sample measuring and diluting device having at least one measuring cavity for extraction of a defined volume from a larger volume of a liquid sample, the method comprising:
-
operatively connecting the disposable device to the instrument, said instrument comprising a measuring unit adapted to measure a sample volume dependent sample parameter, and electronics adapted to process signals from the measuring unit; inputting or presenting to the instrument data directly or indirectly related to an established volume value of the at least one measuring cavity of the disposable device from an information carrier applied to or distributed with the disposable device; and performing a correction for compensation of differences in the established volume value to obtain a corrected sample volume dependent sample parameter on the instrument. - View Dependent Claims (9, 10, 11, 12, 13)
