Detecting Alkanes and other Saturated Hydrocarbons with the 4430 Photoionization Detector (PID)

The OI Analytical Model 4430 Photoionization Detector (PID) is a uniquely-designed gas chromatograph (GC) that selectively detects and measures the presence of both aromatic and olefinic hydrocarbons when present in solutions containing alkanes and other saturated hydrocarbons.

Through the use of OI Analytical’s patented Window Sweep™ design, the Model 4430 prevents the sample stream from coming into contact with and potentially contaminating the lamp window.

Furthermore, this unique design also allows analysis of photosensitive compounds, which would otherwise combine to form a polymer on the window surface.
