Factors affecting spectrophotometer reading Were you concerned about magnesium stearate? Ultravioletvisible spectroscopy or ultraviolet-visible spectrophotometry refers to absorption. The most important factor affecting this is the stray light level of the monochromator. The only drawback in this method is that it can be very influenced by factors like size, temperature, pH and errors in the equipment, causing a major effect due to the lack of other chemical or.

Sep 06,  · You must "zero" your spectrophotometer before using it so all of your absorbance readings can have a baseline to be compared to. For example, if your protein sample was diluted with distilled water, you would zero or "blank" the spectrophotometer using just distilled water, that way the only difference between the absorbance readings can be attributed to protein concentration in the Views: K. Readings were performed as recommended for the kit by using the nm and nm filters on the spectrophotometer I Awareness Technology (Table 1). The other two reading plates used comprised only a nm filter, spectrophotometer II - Bio- Rad (iMark) (Table 2) and spectrophotometer III Thermo Scientific (Multiskan Go) (Table 3).Author: Rogério Reis Conceição. The concentration (c) of a substance in a sample is one of three factors that affect the amount of light absorbed by a sample. The other two are path length (l), that is the distance the light travels through the sample, and the extinction coefficient of the absorbing substance (Ε).

Uncontrolled changes in these factors can introduce inaccuracy and imprecision by altering the position (max) and intensity (max) of the absorption peaks of the chromophore in the compound.
