Relier Pairs UV-Visible Spectroscopy Matching ActivityVersion en ligne Match the instrument component to its characteristic or function. par Heather Holmes 1 This is a single-channel semiconductor detector in which a current is generated when exposed to light. 2 This emits visible radiation. 3 This selects a narrow band of wavelengths. 4 This multi-channel detector can collect electrons over a period of time, which allows for the detection of low-power signals. 5 This is a multi-channel detector that can detect many wavelengths simultaneously. 6 This is a single-channel detector that measures the current from photo-generated electrons, but does not amplify the signal. 7 This emits UV radiation. 8 This emits radiation of different wavelengths, depending on the semiconductor material. 9 This is a single-channel detector that amplifies the signal using multiple dynodes.
