Abstract:
A Czerny-Turner type spectrometer has been designed and operated as a rapid scanning instrument by placing a rotating mirror near the exit slit. Using a helium-neon gas laser, resolution of 0.027 A has been measured at scanning rates of 0.4 A/microsec. Data have been taken with the scanning rate of 6 A/microsec, which could have been increased an order of magnitude if desired. A scanning range of 1-600 A depending on the grating and mirrors used has been obtained. Applications shown included the shift and shape of xenon spectral lines in a pulsed arc discharge. The associated electronics required for synchronization are included.

Raman Spectroscopy Instrumentation: Overview
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
Inductively Coupled Plasma Atomic Emission Spectroscopy: Instrumentation
There are three main types of inductively coupled plasma atomic emission spectroscopy (ICP-AES) instruments: sequential, simultaneous multichannel, and Fourier transform instruments, with the latter being less commonly used.
