Description
The Model 4430 Photoionization Detector (PID) is a GC detector that selectively responds to aromatic and olefinic hydrocarbons in the presence of alkanes and other saturated hydrocarbons. The detector assembly contains an ionizing chamber, UV lamp, and column makeup adapter and uses a standalone, high-voltage power supply for the UV lamp.

The 4430 PID features a unique patented Window Sweep™ design that prevents the sample stream from contacting and contaminating the lamp window. It also allows analysis of photosensitive compounds, which would otherwise polymerize on the window surface. The PID is available for installation on most GC manufacturer’s instruments.
