Abstract

Introductory experiments were designed to demonstrate the characteristics of basic components of a spectrophotometer using an IL AA/AE spectrophotometer. Emissive properties of various types of radiation source; resolving power of wavelength selectors and response of photodetectors were investigated through simple experiments. Everyday radiation sources and wavelength selectors could also be studied. Obsolete old model instrument could be adopted for the proposed demonstrations. With these experiments, students were prepared to learn many other more complicated spectrophotometric instruments.
