How does photoionization detector work? – AnswersToAll

· A photoionization detector or PID is a type of gas detector. Typical photoionization detectors measure volatile organic compounds and other gases in concentrations from sub parts per billion to 10 000 parts per million (ppm). What is at the heart of the photoionization detector? The heart of the photoionization detector is an ultraviolet source, which is essentially a lamp. Early versions of ...

The Problem with PIDs (photoionization detectors) and VOC ...

· PIDs or photoionization detectors are also known as volatile organic compound (VOC) detectors. We love PIDs because they’re a great tool but people believe them without question way too often. Think of a PID as a very powerful UV lamp. When the energy from that lamp comes into contact with a gas molecule, it temporarily splits (ionizes) the gas molecule into pieces (ions). These ions …

Data for First Responder Use of Photoionization Detectors ...

A photoionization detector is a field instrument that is relatively simple and easy to use. It provides rapid information about volatile organic compounds (VOCs) in air samples. Stand-alone PIDs are usually classified as a total organic vapor (TOV) analytical method. That is, they provide information about the relative magnitude of contamination, but are unable to directly distinguish specific ...

Photoionisationsdetektor – Wikipedia

The photoionization detector (PID) can be used to analyze a wide variety of compounds, including aliphatic and aromatic hydrocarbons, amines, and organic sulfur compounds. Key features of the PID that make it suitable for detecting taints are its sensitivity, generally lower than an FID or FPD, and its wide linear dynamic range. It is also nondestructive and can be coupled in series with other detectors.

Flow-through microfluidic photoionization detectors for ...

A photoionization detector (PID) is well known for its high sensitivity, large dynamic range, and non-destructive vapor detection capability. However, due to its tardy response, which results from the relatively large ionization chamber and dead volume, the application of the PID in gas chromatography (GC) has been limited. Here, we developed a rapid, flow-through, and highly sensitive ...
