Describe some advantages ICP has over other elemental analysis method. What is the cause of signal interference and how can interference be dealt with? What is a plasma? Where can plasma be found naturally? Many ICP instruments can measure emission radially and axially (ours cannot measure both simultaneously). Explain what this means and describe the usefulness of each.Why is pure water called 18 MΩ water?

Question 5:
How would dust and oil on the glass plates affect the
results?
EXPERIMENT 10 THIN FILM INTERFERENCE Light from a monochromatic source is shined downward on two glass plates that are separated at one end by a hair. Light that is reflected from the top and bottom surfaces of the wedge-shaped thin film of air undergoes interference, and a series of dark and light lines are seen. By counting the number of dark or light lines over a...
