The Model 4430 Photoionization Detector (PID) is a uniquely-designed gas chromatograph (GC) that selectively responds to aromatic and olefinic hydrocarbons in the presence of alkanes and other saturated hydrocarbons.
Description
4430 Photoionization Detector (PID)
The Model 4430 Photoionization Detector (PID) is a uniquely-designed gas chromatograph (GC) that selectively responds to aromatic and olefinic hydrocarbons in the presence of alkanes and other saturated hydrocarbons.
The Model 4430 PID’s unique patented Window Sweep™ design prevents the sample stream from contacting and contaminating the lamp window. It also allows analysis of photosensitive compounds, which would otherwise combine to form a polymer on the window surface.
Features:
- UV-lamp Window Sweep design minimizes fouling from window surface contamination
- Lampsaver™ circuit extends lamp lifetime by turning off when not in use
- Direct interface to ELCD, XSD, or FID to form tandem detector systems; requires only one detector port
- Detector vent for venting undesirable sample solvents
- Compatible with packed and capillary columns
- Custom engineered to fit specific GC models
- Easy operation and maintenance
