Max wavelength absorbance
Web11 nov. 2009 · So if the peak absorbance is below 1.0, then using the peak wavelength is best, but if the peak absorbance is well above 1.0, you might be better off using another wavelength where the absorbance is closer to 1. Another issue is calibration curve non-linearity, which can result in curve-fitting errors. WebUV absorption spectrum of benzaldehyde and acetophenone in water (Fig. 6) shows the maximum wavelength λ max at 248 nm and 244 nm respectively, assigned to the …
