• Directly interfaces to most GC makes and models

Photo Ionization Detector (PID)

Getting the most out of your GC is easy with the Model 4430 PID, the detector of choice for aromatics and unsaturated hydrocarbon analysis. Its patented Window Sweep™ design prevents the sample stream from contacting and contaminating the lamp window. The Model 4430 PID has been engineered to give you the reliable and stable performance that you expect.

Features

• Unique Window Sweep design minimizes window surface contamination
• Directly interfaces with an XSD, ELCD, or FID for a tandem detector system that occupies only one detector port
• Lampsaver™ circuit extends lamp lifetime by turning off lamp when not in use
• Custom engineered to fit specific gas chromatograph models
• Compatible with packed and capillary columns
• Conical seals to prevent detector leaks
• Easy to operate and maintain
• Uses apporximately ten times lower gas flows

Pulsed Flame Photometric Dectector (PFPD)

Accomplish unmatched selective detection of over 28 elements with the Model 5380 PFPD’s latest advances in detector design. Superior sensitivity and selectivity, increased reliability, and lower maintenance costs make the Model 5380 the smart detector choice to enhance laboratory productivity. Dual channel analog output simultaneously detects sulfur and phosphorus, sulfur and carbon, or any other dual element output. With WinPulse™ software included with the PFPD, setting and optimizing operational parameters are easy. The Model 5380 provides the powerful tool you need to handle the most demanding analytical challenge.

Features

• Selective detection of over 28 elements
• Dual-channel output provides simultaneous detection of two elements
• Provides superior sensitivity and detectivity
• Ability to tune the PFPD's selectivity provides up to three orders of magnitude over conventional FPD's
• Digital signal processing permits storage and post-processing of emission spectrum
• Dual gate capabilities optimizes selectivity
• Improves long-term stability and reduces maintenance costs compared to some S and P selective detectors
• Uses approximately ten times lower gas flows
• Self-cleaning design prevents soot formation
• Avoids flameouts caused by water, solvents, etc.
• Optional PFPD View Software

S-Pro Sulfur Analysis System

The S-PRO System analyzes sulfur compounds in gaseous and liquified petroleum gas (LPG) streams. The completely automated GC system incorporates OI Analytical’s Pulsed Flame Photometric Detector (PFPD), providing extremely stable performance over extended time with virtually no routine detector maintenance. The system’s overall optimized design coupled with the PFPD’s superb sensitivity and performance provides reproducible sulfur compound analysis from ppm to low ppb concentrations.

Features

• Provides automated sample injection, calibration, and QA/QC
• Integrated permeation oven provides single or multiple calibration or QC standards
• Automated injection of calibration or check samples provided by the built-in valving and permeation system eliminates using unstable, expensive sulfur gas standards
• Sulfinert™-treated sample pathway minimizes absorptive surfaces for optimal performance, particularly for low sulfur concentrations
• Proven PFPD detector provides stability, sensitivity, selectivity, equimolar sulfur response, calibrations in linear or quadratic modes, and multi-element detection capability
• Single-digit ppb sensitivity for sulfur analysis
• Full EPC control of all injector, permeation oven, and detector gases
• Using additional or alternative detectors (PID, ELCD, XSD, or tandem configurations) allows the analysis of other compounds of interest

 

XSD Halogen Specific Detector

The Model 5360A XSD’s advanced detector design gives you the edge in halogen-specific detection. It’s so simple that all you need is air to operate this detector—no catalyst tubes, solvents, resin cartridges, pumps, radioactive sources, or transfer lines. The XSD’s revolutionary design minimizes complexity, so you benefit with fewer maintenance problems and lower operating costs. It’s the perfect fit for sensitive GC analysis of halogen-containing pesticides and herbicides, chlorinated VOCs, and PCBs.

Features
