Its main innovation is the introduction of a reference wavelength to correct the possible non-specific optical changes of the system. The performance of the instrumentation has been tested on a laboratory setup and with integrated optical absorbance sensors. 000131236 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000131236 590__ $$a1.297$$b2007 000131236 591__ $$aENGINEERING, MULTIDISCIPLINARY$$b10 / 67 = 0.149$$c2007$$dQ1$$eT1 000131236 591__ $$aINSTRUMENTS & INSTRUMENTATION$$b19 / 54 = 0.352$$c2007$$dQ2$$eT2 000131236 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000131236 700__ $$aPuyol,M. 000131236 700__ $$0(orcid)0000-0002-6144-7928$$aSalinas,I.$$uUniversidad de Zaragoza 000131236 700__ $$aAlonso,R. 000131236 700__ $$aAlonso,J. 000131236 700__ $$aDominguez,C. 000131236 700__ $$0(orcid)0000-0003-3505-0078$$aGarces,I.$$uUniversidad de Zaragoza 000131236 7102_ $$15008$$2800$$aUniversidad de Zaragoza$$bDpto.
