To determine the instrument detection limit of Pb2+ ions, a student made 10 blank solutions and measured their signals. The standard deviation of the signals are 0.199. Then the student made a series of Pb2+ standard solutions (concentration range is 2.00 ppm to 15.00 ppm) and measured their signals. The equation of the calibration curve is: y = 3.413 x+ (b). What is the instrument detection limit of Pb2+ in ppm?

Absorbance measurements in the range of A = 0.3 - 2 are considered the most accurate. Why are absorbance measurements of 0.05 and 2.5 considered inaccurate? 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. At A = 2.5, the transmission is too high for an accurate measurement. The difference in the absorbance of the sample and reference is too small at A = 0.05. At A = 2.5, the detector is saturated because too much light is reaching the detector. At A = 2.5, a sufficient amount of light does not reach the detector for an accurate measurement.

Suppose a student is preparing a set of standard solutions for use in a spectrophotometric study. If percent transmittance, %T, were measured in the standard solutions before the color had a chance to fully develop, the measured value would be compared with solutions that have allowed the color to fully develop.
