Photoionization Detectors (PID)

Next-Gen Photoionization Detection with Patented Window Sweep™ Technology

Stop worrying about window fouling and frequent maintenance. The Model 4430 PID is engineered for high-performance analysis of aromatics and unsaturated hydrocarbons, delivering unmatched reliability for even the most challenging samples.

The Innovation: Patented Window Sweep™

The common failure point of PIDs is lamp contamination. Our unique Window Sweep™ design creates a protective barrier that prevents the sample stream from touching the lamp window.

• Zero Polymerization: Safely analyze photosensitive compounds that would otherwise foul the window surface.

• Maximum Uptime: Dramatically reduces cleaning frequency and maintenance costs.

Why Choose the 4430 PID?

• Lampsaver™ Circuit: Automatically turns the lamp off when not in use, significantly extending lamp life.

• Tandem Flexibility: Easily interfaces with XSD, FID, or ELCD to provide two simultaneous chromatograms from a single injection—saving time and bench space.

• Universal Compatibility: Custom-engineered to fit most major GC brands.

• Clean Results: Integrated detector vent for flushing out unwanted sample solvents.

Key Applications

• Environmental: Compliance with US EPA Methods (502.2, 8021), BTEX, and UST monitoring.

• Petrochemical: Accurate analysis of Aromatics, Olefins, and VPH.

• Industrial: Air pollution and waste characterization.

Upgrade to Tandem Power: Model 4450

Looking for the ultimate setup? The Model 4450 Tandem PID/FID combines the 4430 PID with the 4410 FID in one unit. Get selective aromatic detection and universal hydrocarbon response in a single run, using only one detector port.

"Unrivaled protection. Simultaneous results. Proven reliability."
