It is very important to consider factors that can affect the position and intensity of absorbance such as temperature, concentration of sample, pH of solution, presence of impurities or bubbles in solution, and solvents used. These should be controlled before and during analysis to obtain high-precision measurements and avoid baseline shifts by performing all spectral analyses under the same conditions. Any solvent used should be completely transparent to avoid modification of analyte absorbance.
