Problems solved by technology
Past analysis results cannot be used in new samples or analysis conditions that have not been analyzed until now
In addition, the samples used for measurement, measurement conditions, and original measurement data contain information that should be protected, such as technical secrets and product information, so it is difficult to share with other users.
[0006] In addition, the influence of the number of times the consumables are used on the analysis results varies greatly depending on the analysis conditions, so it is difficult to estimate the change of the new analysis results even if the past analysis results of the same consumables and lot numbers are simply used.

[0033] figure 1 It is a figure which shows the structure of the analysis apparatus 1 of 1st Embodiment.
[0034] The analysis device 1 includes a measurement data acquisition unit 3 , a difference data generation unit 6 , a case data set storage unit 2 , an aging degradation estimation unit 4 , and an aging degradation correction unit 5 .
[0035] The case data set storage unit 2 stores a plurality of case data sets. One case data set includes difference data indicating the amount of change from the initial state measurement data with respect to measurement data measured at a plurality of time points in the same sample and under the same measurement conditions.
[0036] Samples include blood, caffeine, nicotine, and the like. The measurement conditions include conditions related to deterioration of consumables and measurement data, such as analysis time, temperature, pressure, flow rate of liquid, types of consumables, and the like. The measurement data include a chromatogr...

The invention provides an analysis device, an analysis system, and an analysis method. A case data set storage unit (2) includes a plurality of case data sets including difference data representing, avariation from measurement data taken at an initial state to measurement data taken at a plurality of points of time for the same sample under the same measurement condition. An aging degradation estimation unit (4) uses these case data sets to output difference data representing an estimate value of a variation from the measurement data taken at the initial state to measurement data taken, by ameasurement device (10), at or after a first elapsed time, based on difference data representing a variation from the measurement data taken at the initial state to measurement data taken at a plurality of points of time that precede the first elapsed time. An aging degradation correction unit (5) corrects the measurement data taken at or after the first elapsed time, based on the output difference data.
Description
technical field [0001] The invention relates to an analysis device, an analysis system and an analysis method. Background technique [0002] The analysis device includes consumables such as a detector lamp and a column inside. Depending on the number of times consumables are used, even in analyzes performed on the same sample and analysis conditions, analysis results may vary due to deformation of the peak shape, shift in retention time, or the like. In order to correct for changes in analysis results, a standard sample is analyzed in advance and stored as past analysis results. Ability to detect changes in analysis results by comparing new analysis results with past analysis results. In addition, it is possible to estimate a change in analysis results from a plurality of past analysis results and to correct the change. [0003] For example, International Publication No. 2001 / 093142 describes a method of correcting measurement results based on the number of times of use a...
