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
