Safeguard Catalyst Performance and Save Millions with High-Precision, ppb-Level Detection

In petrochemical, refining, and natural gas laboratories, even trace levels of sulfur and nitrogen compounds can cause big problems, poisoning catalysts, degrading product purity, and putting compliance at risk. But many sulfur chemiluminescence detectors (SCDs) demand frequent recalibration and ongoing maintenance just to stay accurate.

PAC Powered by AC’s SeNSe² for gas chromatography (GC) changes that. Built for long-term stability and precision, this advanced sulfur and nitrogen detector combines day-over-day reliability, true equimolar response, and ppb-level sensitivity, so you can focus on results, not recalibration.

Precision Detection for Catalyst Protection

Sulfur and nitrogen detection isn’t just about measurement; it’s about protecting multi-million-dollar assets. Catalyst deactivation caused by trace contaminants can disrupt entire operations. SeNSe² provides the confidence needed to safeguard catalysts and maintain purity across your petrochemical streams.

Our GC’s equipped with SeNSe² detectors are fully compliant and application-ready for key ASTM methods, including:

• ASTM D5623 – Sulfur compounds in light petroleum liquids
• ASTM D5504 – Ultra-trace sulfur in natural gas and gaseous fuels
• ASTM D7011 – Trace thiophene in refined benzene

Whether analyzing light liquids, gaseous fuels, or complex feedstocks, SeNSe² ensures accurate, repeatable results, even under the toughest analytical conditions.

Simplified Maintenance and Integration

With a built-in G-Cal validation module, automated leak checks, and touchscreen diagnostics, SeNSe² minimizes downtime and simplifies upkeep. Its modular design integrates seamlessly into GC platforms, making it the smart upgrade for any lab ready to boost reliability without overhauling existing systems.
