what is the dynamic range for an instrument? how is it related to a calibration curve?
Homework Answers
Dynamic range: In the dynamic range the response changes when the analyte concentration is changed but the relationship may be non-linear. If the response is linear it can be specified as a dynamic linear range.
Calibration curve: The calibration curve is a plot of how the instrumental response, the so-called analytical signal, changes with the concentration of the analyte (the substance to be measured). The operator prepares a series of standards across a range of concentrations near the expected concentration of analyte in the unknown.
The relation between dynamic range and calibration curve is shown in below figure.

In order to magnify the calibration in an An instrument dial instrument dial by 2 times (M 2), a lens is placed toward the surface of the dial (as shown in the right figure). A flat surface of the lens connects with the dial surface (assuming that the spacing is zero). The refraction indices of air and lens are 1.0 and 1.5, respectively. The thickness of the lens is 30mm. Please compute: 1) Image position of the instrument dial from...
