Question

Let's imagine that you were going to start a company that produces spectroscopes to sell to general chemistry students. How could you ensure that all the spectroscopes created the same calibration line and equation? What would you need to be sure it was always the same? What could be changed without affecting the calibration?

Answer 1

Spectroscopes needs to be properly maintained in terms of conditions it is operated in. Proper standards are used to calibrate spectroscopes at regular periods of time. All the spextroscopes must be run with same concentration of standards to ensure all give same claibration curves and equations thereof. Light source used must be kept properly and be relaced in case of non-functional condition. Also the cell used for measurement must be clean and be kept in scratch free area. One can change the solution concentration to be mesured without changing the calibration.
