A computer-implemented method for spectroscopic analysis of biological material, the method including an analysis step comprising: taking (S803), by a liquid router , a plurality of samples of biological material from a plurality of sources , wherein each sample of the plurality of samples is taken from a source of the plurality of sources ; determining whether a spectroscopic analysis for each sample of the plurality of samples is predicted to be ambiguous in that the interpretation of the feature(s) of the spectrum is affected by at least two non-discriminable factors being temporally correlated, wherein the at least two non-discriminable factors comprise only factors of interest whose properties are desired to be obtained via the spectroscopic analysis or comprise both factor(s) of interest and confounding factor(s) whose properties are not to be obtained via the spectroscopic analysis; if the spectroscopic analysis for a given sample of the plurality of samples of biological material is predicted to be ambiguous, performing a disambiguating step to break the correlation of the at least two non-discriminable factors, the disambiguating step comprising: routing (S805), by the liquid router , the given sample of biological material to a manipulation station ; manipulating (S807), at the manipulation station , the given sample of biological material in order to impact the spectroscopic analysis; delivering (S813), by the liquid router , the given manipulated sample of biological material from the manipulation station to at least one flow cell ; performing (S815), by at least one spectrometer connected to the at least one flow cell, the spectroscopic analysis of the given manipulated sample of biological material. taking (S803), by a liquid router , a plurality of samples of biological material from a plurality of sources , wherein each sample of the plurality of samples is taken from a source of the plurality of sources ; determining whether a spectroscopic analysis for each sample of the plurality of samples is predicted to be ambiguous in that the interpretation of the feature(s) of the spectrum is affected by at least two non-discriminable factors being temporally correlated, wherein the at least two non-discriminable factors comprise only factors of interest whose properties are desired to be obtained via the spectroscopic analysis or comprise both factor(s) of interest and confounding factor(s) whose properties are not to be obtained via the spectroscopic analysis; if the spectroscopic analysis for a given sample of the plurality of samples of biological material is predicted to be ambiguous, performing a disambiguating step to break the correlation of the at least two non-discriminable factors, the disambiguating step comprising: routing (S805), by the liquid router , the given sample of biological material to a manipulation station ; manipulating (S807), at the manipulation station , the given sample of biological material in order to impact the spectroscopic analysis; delivering (S813), by the liquid router , the given manipulated sample of biological material from the manipulation station to at least one flow cell ; performing (S815), by at least one spectrometer connected to the at least one flow cell, the spectroscopic analysis of the given manipulated sample of biological material. routing (S805), by the liquid router , the given sample of biological material to a manipulation station ; manipulating (S807), at the manipulation station , the given sample of biological material in order to impact the spectroscopic analysis; delivering (S813), by the liquid router , the given manipulated sample of biological material from the manipulation station to at least one flow cell ; performing (S815), by at least one spectrometer connected to the at least one flow cell, the spectroscopic analysis of the given manipulated sample of biological material. <EOS>
