| titleOfInvention | Normalizing spectroscopy data with multiple internal standards |
| abstract | Normalization of spectra, comprising: preparing (1-2) experiment runs; processing (1-4) them in an LC/MS spectrometer to obtain a spectrum for each experiment run; internally representing (1-10) each spectrum as mass/charge (m/z) versus retention time (rt); performing a peak detection (1-12) of each spectrum; internally aligning (1-14) the detected peaks; and normalizing (1-18) the spectra, which comprises modelling variation of Yij, denoted δYij, as a function of variability of Ω, denoted f(δΩ). δ denotes variability of a quantity, (the quantity's deviation from an average value of the quantity over the sample runs); X = Xij = intensity matrix for ail peaks, mapped to Y via a first transformation function / such that Y = f1(X); Z = Zij = intensity matrix for internal standard peaks (IS1 - IS4), mapped to Ω via a second transformation function t such that Ω = f1(Z). i denotes peaks: i → {m/z, rt} and i = 1... N; and j denotes experiment runs. |
