Integrated micro photoionization detector with ultra-thin UV transmission window

摘要

An integrated microfluidic photoionization detector (PID) is provided that includes a microfluidic ionization chamber and a microfluidic ultraviolet irradiation chamber configured to generate ultraviolet photons. An ultra-thin transmission window is located between the microfluidic ionization chamber and the microfluidic UV irradiation chamber, which allows UV photons to pass from the microfluidic UV irradiation chamber into the microfluidic ionization chamber. Become. One or more VOCs comprising a gas chromatography (GC) unit comprising at least one gas chromatography column and an integrated microfluidic photoionization detector (PID) located downstream of the gas chromatography (GC) unit. A detection system for the analyte is also provided.
