Photometric linearity
WebPhotometric linearity refers to how accurately the instrument measures absorbance with increasing concentration. Poor photometric linearity will produce incorrect results. Which … WebPhotometric linearity is a measure of the linearity of the measured values (e.g. absorbance) as a function of increasing concentration. This is especially important for quantitative applications. Photometric linearity can be determined with the same procedures and filters used to determine photometric accuracy, however, at three concentrations ...

WebLinearity is also often considered to be an important factor for per-formance verification. However, the primary instrumental reason for non-linearity is tested for. Other reasons for non-linearity are strongly sample or sampling dependent and for this reason it is the authors opinion that this para-meter is best measured during a system ...
