1.1 This practice covers photomultiplier properties that are essential to their judicious selection and use of photomultipliers in emission and absorption spectrometry. Descriptions of these properties can be found in the following sections:
Section Structural Features4 General4.1 External Structure4.2 Internal Structure4.3 Electrical Properties5 General5.1 Optical-Electronic Characteristics of the Photocathode5.2 Current Amplification5.3 Signal Nature5.4 Dark Current5.5 Noise Nature5.6 Photomultiplier as a Component in an Electrical Circuit5.7 Precautions and Problems6 General6.1 Fatigue and Hysteresis Effects6.2 Illumination of Photocathode6.3 Gas Leakage6.4 Recommendations on Important Selection Criteria71.2 Radiation in the frequency range common to analytical emission and absorption spectrometry is detected by photomultipliers presently to the exclusion of most other transducers. Detection limits, analytical sensitivity, and accuracy depend on the characteristics of these current-amplifying detectors as well as other factors in the system.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
