Absorbance measurements in the range of A = 0.3-2 are considered the most accurate. Why would absorbance measurements of 0.05 and 2.5 be considered inaccurate? Select all that apply. 1. At A = 2.5, the detector is saturated because too much light is reaching the detector. 2. The difference in the absorbance of the sample and reference is too small at A = 0.05.3. If the absorbance is too high (A = 2.5), the signal difference between the sample and the reference is too small for an accurate measurement. 4. At A = 2.5, a sufficient amount of light does not reach the detector for an accurate measurement. 5. At A = 2.5, the transmission is too high for an accurate measurement.
