Abstract

Abstract A method of validating measurement of a kinetic chemical reaction comprises a first tier of validation to validate the ability of a measurement and detection system to provide accurate data, a second tier of validation to validate the initiation and control of the kinetic chemical reaction and a third tier of validation which verifies first that the expected kinetic chemical reaction has proceeded in a characteristic manner and direction, and second, that parameters of the chemical reaction are within limitations characteristic of the measurement and detection system of a measuring instrument investigating the reaction.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 242 words
A method for validating measurements made of a sample undergoing a kinetic chemical reaction for use in a scientific instrument including a system for measuring and a system for processing measured information of a sample material undergoing a kinetic chemical reaction comprising: a first step of validating the ability of the measurement system being used in said instrument to measure the chemical reaction to provide accurate measurement of a significant parameter of the chemical reaction, before initiation of the chemical reaction; initiating a kinetic chemical reaction with the sample material; a second stop of validating the initiation of the chemical reaction and progress of the chemical reaction in a controlled manner; measuring the kinetic reaction with said sample material and obtaining data relating to said measurement; a third step of validating the data measured indicating information regarding said significant parameter in the chemical reaction, said third step comprising: first determining that values of data obtained from measurement of the reaction do not exceed the ability of the measurement system to perform said measurements; second, determining that values of data obtained from measurement of the reaction are within a selected range of deviation from the theoretically expected measurements of the reaction; and third, determining that random deviation of measurements of the reaction from theoretically expected measurements are within a selected range of deviation; and providing validated data to the system for processing measured information of a sample material undergoing a kinetic chemical reaction.
Claim 2
Independent Claim 242 words
A method for validating measurements made of a sample undergoing a kinetic chemical reaction for use in a scientific instrument including a system for measuring and a system for processing measured information of a sample material undergoing a kinetic chemical reaction comprising: a first step of validating the ability of the measurement system being used in said instrument to measure the chemical reaction to provide accurate measurement of a significant parameter of the chemical reaction, before initiation of the chemical reaction; initiating a kinetic chemical reaction with the sample material; a second stop of validating the initiation of the chemical reaction and progress of the chemical reaction in a controlled manner; measuring the kinetic reaction with said sample material and obtaining data relating to said measurement; a third step of validating the data measured indicating information regarding said significant parameter in the chemical reaction, said third step comprising: first determining that values of data obtained from measurement of the reaction do not exceed the ability of the measurement system to perform said measurements; second, determining that values of data obtained from measurement of the reaction are within a selected range of deviation from the theoretically expected measurements of the reaction; and third, determining that random deviation of measurements of the reaction from theoretically expected measurements are within a selected range of deviation; and providing validated data to the system for processing measured information of a sample material undergoing a kinetic chemical reaction.
Claim 3
Independent Claim 323 words
A method for validating measurements made of a sample undergoing a kinetic chemical reaction for use in a scientific instrument including a system for measuring and a system for processing measured information of a sample material undergoing a kinetic chemical reaction comprising: a first step of validating the ability of the measurement system being used in said instrument to measure the chemical reaction to provide accurate measurement of a significant parameter of the chemical reaction, before initiation of the reaction; initiating a kinetic chemical reaction with the sample material; a second step of validating the initiation of the chemical reaction and progress of the chemical reaction in a controlled manner; measuring the kinetic reaction with said sample material and obtaining data relating to said measurement; a third step of validating the data measured indicating information regarding a significant parameter in the chemical reaction, said third step comprising: first determining that values of data obtained from measurement of the reaction do not exceed the ability of the measurement system to perform said measurements; second, determining a sum of deviations of individual data points measured from a least squares linear regression of all data points measured, and dividing said sum by the slope of said linear regression, to determine an index of random deviation; third, determining a partial slope of at least two segments of the data measured, each segment comprising a group of data points, less than the whole of said data, determining a difference between the partial slopes of said segments and dividing each determined difference in slope by a square root of an average value of the partial slopes to determine a non-linearity index indicating a non-linear relationship of said date; and fourth, comparing a sum of said indexes with a selected value limitation characteristic of the specific chemical reaction being measured; and providing validated data to the system for processing measured information of a sample material undergoing a kinetic chemical reaction.
