Photoionization Detectors.Mine Safety Appliances Mine Safety Appliances, or MSA, is a maker of sophisticated safety products that help protect workers who may be exposed to a variety of hazardous conditions. The company’s product line includes gas monitoring and detection instruments, filter-type respirators, gas masks, Co. (MSA) has published a white paper entitled Photoionization Detectors (PIDs), Technology for Detection of Volatile Organic Compounds. The paper summarizes the theory behind photoionization Photoionization The ejection of one or more electrons from an atom, molecule, or positive ion following the absorption of one or more photons. The process of electron ejection from matter following the absorption of electromagnetic radiation has been under detection sensors, describes some of the factors that affect PID (1) (Process IDentifier) A temporary number assigned by the operating system to a process or service. (2) (Proportional-Integral-Derivative) The most common control methodology in process control. performance, and includes key factors to consider when selecting a PID.
