Abstract
Abstract The present invention relates to a method of analyzing a reaction rate in chemical analysis, in which a plurality of time region bands wherein the reaction rate is measured are set to be different in time series, a sample high in active value is calculated based on the data contained in the region band positioned forward in time series, and a sample low or normal in active value is calculated based on the data contained in the region positioned backward in the time series.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
154 words
A method of analyzing a reaction rate in chemical analysis, comprising the steps of: reacting at least one sample and at least one reagent; first measuring at various time points the level of reaction of a sample and the reagent so as to provide a plurality of measurement region bands; dividing each of the plurality of said measurement region bands different which have time series n which the said reaction rate is measured and stored; finding within said measurements one of said samples high in active value by using data included in the region band in a forward position in said time series; second measuring a sample which will have a normal or low active value; and finding an active value by using a data look up of data which was part of the measurement indicated in the region band in a backward position in said time series in relation to said forward position.
Claim 2
Independent Claim
154 words
A method of analyzing a reaction rate in chemical analysis, comprising the steps of: reacting at least one sample and at least one reagent; first measuring at various time points the level of reaction of a sample and the reagent so as to provide a plurality of measurement region bands; dividing each of the plurality of said measurement region bands different which have time series n which the said reaction rate is measured and stored; finding within said measurements one of said samples high in active value by using data included in the region band in a forward position in said time series; second measuring a sample which will have a normal or low active value; and finding an active value by using a data look up of data which was part of the measurement indicated in the region band in a backward position in said time series in relation to said forward position.
Claim 3
Dependent Claim
133 words
A method of analyzing a reaction rate in chemical analysis as claimed in claim 1 wherein said reacting and first measuring steps further comprise: reacting a first sample and a first reagent and measuring the reaction rate thereof, characteristic values such as the active value and the concentration concerning the sample to be measured are measured and analyzed the measurement of the characteristic values concerning said sample to be measured is carried out in a measurement mode that uses the region band positioned backward in said time series, and when a number of effective measured data points obtained in said measurement mode is less than a predetermined value, an analysis of the reaction is automatically carried out based on the measurement mode that uses the region band positioned forward in said time series.
Claim 4
Dependent Claim
49 words
A method of analyzing a reaction rate in chemical analysis as claimed in claim 1, wherein one of the plurality of the measurement region bands different in time series is a region band including a lag time and the other is a region band not including the lag time.
Claim 5
Dependent Claim
41 words
A method of analyzing a reaction rate in chemical analysis as claimed in claim 1 or 2, wherein the selection of the region band to be used of the plurality of the measurement region bands is decided by a manual operation.
