Abstract: Disclosed is a calibration curve setting method for setting a calibration curve, the calibration curve setting method including: creating a first calibration curve on the basis of a measurement value obtained by measuring a standard sample for which a concentration of a predetermined component is known; creating a second calibration curve by correcting the created first calibration curve; displaying a screen configured to support an operator for restoring the second calibration curve to the first calibration curve; receiving an instruction of restoring the second calibration curve to the first calibration curve; and displaying the first calibration curve upon receiving the instruction of restoring.

Abstract: The present teachings relate to a method of generating calibration information during a real-time polymerase chain reaction (RT-PCR) or other amplification reaction. A sample well plate or other support can contain one or more dyes or other reference materials that are subjected to the same RT-PCR thermal cycles or other conditions used to conduct amplification or other reactions on a biological sample. A set of maxima values and a set of minimum values, and/or other calibration information useful for adjusting emission data for sample dyes can be recorded, for example, for 10 cycles, 20 cycles, or each cycle of a complete RT-PCR run. Such testing of dye response under realistic operating conditions can enable more accurate characterization of plate, dye, filter, or instrument response and therefore more accurate calibration corrections and other and/or adjustments.

Abstract: A method for determining a physical property of a biological sample. The method comprises the steps of: acquiring a set of preliminary calibration signals of a first lot of a reagent using an automatic analyzer with a first photometry module; acquiring a reference set of signals of the first lot of the reagent using a calibration analyzer with a second photometry module; determining a set of module specific components by subtracting the reference set of signals from the preliminary calibration signals; acquiring a lot specific set of signals of a second lot of the reagent using the second photometry module; determining a lot calibration for the first photometry module using the set of module specific components and the lot specific set of signals; acquiring a measurement signal of the biological sample using the first photometry module and the second lot of the reagent; and determining a physical property of the biological sample using the measurement signal and the lot calibration.

Abstract: The present teachings relate to a method and system for normalizing spectra across multiple instruments. In an embodiment of the present invention, the method comprises at least one reference instrument and a test instrument. Each instrument comprises at least one excitation filter and at least one emission filter arranged in pairs. Each instrument further comprises a pure dye plate comprising a plurality of wells. Each well contains a plurality of dyes where each dye comprises a fluorescent component. Fluorescent spectra are obtained from each instrument for each dye across multiple filter combinations to contribute to a pure dye matrix Mref for the reference instrument and pure dye matrix M for the test instrument. The pure dye spectra can then be multiplied by correction factors for each filter pair to result in corrected pure dye spectra, then normalized and the multicomponenting data can be extracted.

Abstract: Method for optimising the values of n detection wavelengths of an optical gas sensor capable of carrying out detection of n different gases, comprising the implementation of the following steps: a) calculation of a value of a determinant of an absorptivity matrix ε whose coefficients represent the spectral absorptivity of each of the n gases at n detection wavelengths, step a) being repeated several times, each time modifying at least one of said n detection wavelengths and such that the values of said n detection wavelengths are comprised within a range of values for which the spectral absorptivity of at least one of the n gases is non-zero; b) determination of the values of said n detection wavelengths for which the value of the determinant of the absorptivity matrix ε corresponds to the maximum value amongst the set of previously calculated values.

Abstract: Systems and methods are provided for calibrating emission data or other information signals collected during a polymerase chain reaction (PCR), amplification reaction, assay, process, or other reaction. Calibration of multiple detectable materials can be achieved during a single cycle or run, or during a plurality of runs of the reaction. A reading from every well, container, or other support region of a sample support does not have to be taken. Interpolation can be used to determine values for emission data or other information signals that were not taken, or are unknown, using detected emission data, or other detected information signals. By calibrating the detected emission data and the interpolated data, a more accurate reading of emission data or information signal can be obtained.
