Abstract

Provided is an analysis device or an analysis method, by which highly reliable analysis results can be obtained even in the circumstances where environment temperature changes, while reducing load on the user. The analysis device (1) is provided with a determining means (13) which determines whether environmental temperature measured by means of a temperature measuring means (6) is within a predetermined temperature range or not. The determining means (13) is so configured as to determine whether the environmental temperature is within the predetermined temperature range or not, even in the circumstances where information relating to a target substance in a sample cannot be obtained from the analysis device.

Claims

1. An analysis apparatus for obtaining information with respect to an objective substance contained in a sample, the analysis apparatus comprising:

a temperature measuring unit which measures an environmental temperature;

a storage unit which stores temperature correction data corresponding to the environmental temperature in relation to a predetermined temperature range;

a calculating unit which calculates an analysis value on the basis of the temperature correction data and the information with respect to the objective substance contained in the sample; and

a determining unit which determines whether or not the environmental temperature is within the temperature range, wherein;

the determining unit determines whether or not the environmental temperature is within the temperature range even in such a situation that the information with respect to the objective substance contained in the sample is not obtained from the analysis apparatus.

2. The analysis apparatus according to claim 1, wherein the determining unit is constructed to determine whether or not the temperature is within a temperature range in which the temperature correction data is applicable, depending on whether or not an amount of change per predetermined time of the environmental Itemperature measured a plurality of times by the temperature measuring unit is within a predetermined range.

3. The analysis apparatus according to claim 1, wherein the temperature measuring unit is provided at a portion at which it is possible to measure a temperature in a vicinity of a portion which outputs the information with respect to the objective substance contained in the sample.

4. The analysis apparatus according to claim 1, further comprising additional temperature measuring unit which measures the environmental temperature distinctly from the temperature measuring unit.

5. The analysis apparatus according to claim 4, wherein the determining unit is constructed to determine whether or not the temperature is within a temperature range in which the temperature correction data is applicable, on the basis of a difference between the environmental temperature which is measured by the temperature measuring unit and the environmental temperature which is measured by the additional temperature measuring unit.

6. The analysis apparatus according to claim 4, wherein the additional temperature measuring unit is provided at a portion separated from a portion which outputs the information with respect to the objective substance contained in the sample as compared with the temperature measuring unit.

7. The analysis apparatus according to claim 1, wherein the determining unit determines again whether or not the environmental temperature is within a temperature range in which the temperature correction data is applicable, after a certain time elapses, if it is determined that the environmental temperature is without the temperature range in which the temperature correction data is applicable.

8. The analysis apparatus according to claim 7, further comprising:

a main power source, wherein;

the determining unit stops the main power source or performs electric power saving after a certain time elapses, if it is determined that the environmental temperature is without the temperature range in which the temperature correction data is applicable.

9. The analysis apparatus according to claim 1, further comprising informing unit which informs that the environmental temperature is within the temperature range in which the temperature correction data is applicable or that the environmental temperature is without the temperature range in which the temperature correction data is applicable, on the basis of a determination result obtained by the determining unit.

10. The analysis apparatus according to claim 1, wherein an apparatus, which can be held in a body and which is capable of continuously analyzing the sample, is used as the analysis apparatus.

11. An analysis method for obtaining information with respect to an objective substance contained in a sample, the analysis method comprising:

measuring an environmental temperature;

storing temperature correction data corresponding to the environmental temperature in relation to a predetermined temperature range;

calculating an analysis value on the basis of the temperature correction data and the information with respect to the objective substance contained in the sample; and

determining whether or not the environmental temperature is within the temperature range, wherein,

in the determining, the environmental temperature is within the temperature range even in such a situation that the information with respect to the objective substance contained in the sample is not obtained from the calculating.

12. The analysis method according to claim 11, wherein it is determined in the determining whether or not the temperature is within a temperature range in which the temperature correction data is applicable, depending on whether or not an amount of change per predetermined time of the environmental temperature measured a plurality of times in the measuring is within a predetermined range.

13. The analysis method according to claim 11, wherein a temperature is measured in a vicinity of a portion which outputs the information with respect to the objective substance contained in the sample in the measuring.

14. The analysis method according to claim 11, further comprising additionally measuring the environmental temperature distinctly from the measuring the environmental temperature.

15. The analysis method according to claim 11, wherein it is determined again in the determining whether or not the environmental temperature is within a temperature range in which the temperature correction data is applicable, after a certain time elapses, if it is determined that the environmental temperature is without the temperature range in which the temperature correction data is applicable.
