If more than 2-2.5 KV is neces- sary, it is recommended that a guard ring be used on the anode insulator. These polymers float on both fresh and salt water, enabling them to travel long distances from the initial source of pollution. The study of the electromagnetic spectrum of elements is called Optical Atomic Spectroscopy. 10. An FTIR spectrometer uses an optical device called an interferometer, which modulates all of the infrared frequencies “encoded” into it. It is used for applications such as quality control, process analysis and material identification. An electric arc or spark is passed In traditional arc spectroscopy methods, a sample of the solid was commonly ground up and destroyed during analysis.
