Electrolyte analyzer and its measured data processing method

Abstract

The invention provides an electrolyte analyzer. An electrolyte analyzer comprises an A / D converter (45) for converting analog data outputted from an ion-selective electrode into digital data, a data processing section (46a) for determining the median value of the plural digital data converted from the plural analog data outputted from the ion-selective electrode and outputting the median value as the measured data on an electrolyte, and an operation section (46b) for operating the concentration of an electrolyte contained in a sample according to the measured data on the electrolyte outputted by the data processing section. A method for processing its measured data is also disclosed.

Description

technical field [0001] The invention relates to an electrolyte analysis device and a measurement data processing method thereof. Background technique [0002] Conventionally, as an electrolyte analysis device for analyzing electrolytes contained in samples such as urine or blood, there is known a device that uses an ion selective electrode (Ion Selective Electrode) to measure the concentration of electrolytes (for example, refer to Patent Document 1). Such an electrolyte analyzer uses an ion-selective electrode and a comparison electrode, and measures the electromotive force (the potential difference between the potential detected by the ion-selective electrode and the potential detected by the comparison electrode) of a diluted sample obtained by diluting the sample with a diluent. ), and measure the electromotive force of the standard solution, and measure the concentration of the electrolyte contained in the sample based on the measurement data of these diluted samples an...

AI Technical Summary

Problems solved by technology

[0004] However, in conventional electrolyte analyzers, due to unexpected electrical or mechanical reasons, the measurement signals output from the ion-selective electrode and the reference electrode sometimes contain irregular noise that occurs suddenly and occurs in a pulse-like manner.

Data including such sudden and irregular noise becomes erroneous and cannot be used as measurement data of a sample.

Therefore, the electrolyte analysis device needs to measure again the sample corresponding to the pulse-shaped noise data, and it takes time to measure the sample, so it is desired to have a countermeasure against irregular noise.
