Abstract | An example of the determination of glucose by means of spectrophotometry is used to illustrate a very fundamental question: assuming there is a response of the instrument (here: maximum of absorbance or peak area) to a changed level of concentration of an analyte (sometimes also a term analate is used), is this response linear or not quite linear? The corollary questions are for example: what criteria can be used to evaluate (or assess) the degree of linearity? Would that functional dependence be valid over the whole range of analyte concentrations or, if not, what other mathematical alternatives are available to construct a model which will be giving more reliable results? |
