RKI Instruments offers a targeted and effective solution for benzene detection through the GX-6000 multi-gas monitor, equipped with a 10.0 eV Photoionization Detector (PID) and specialized benzene filtration tube.

• Benzene-Specific Detection Using 10.0 eV PID + Filtration Tube

When used in combination with RKI’s benzene-specific filter tube, this system removes common VOC interferences, allowing the PID to focus solely on benzene molecules.

• Benzene Measuring Mode Uses Temperature to Determine Sampling Time

The GX-6000 will automatically determine the appropriate sampling time to measure benzene through the filter tube based on the current temperature, which can be anywhere from 35 to 135 seconds.

• Dual PID Function

The GX-6000 is the only gas monitor with the capability of operating 2 PID lamps in one instrument

• Smart Sensor Wells

The GX-6000 has 2 smart sensor wells where PID (4 lamp options available), IR, and EC sensors can be switched and automatically recognized by the instrument. 

Versatile Multi-Gas Monitoring Platform
The GX-6000 supports up to six simultaneous gas sensors, allowing for comprehensive atmospheric monitoring in a single device.

What is Benzene and Where is it Found?

Benzene (C6H6) is a volatile, colorless, and highly flammable aromatic hydrocarbon composed exclusively of carbon and hydrogen atoms, placing it within the chemical class of volatile organic compounds (VOCs). Its molecular structure—a ring of six carbon atoms with alternating double bonds—contributes to both its chemical stability and its ability to evaporate easily into the atmosphere. 

Benzene is a naturally occurring component in crude oil and petroleum-based products and is widely encountered across the entire oil and gas value chain, including:

• Upstream operations (e.g., drilling platforms, wellheads)
• Midstream processes (e.g., pipelines, storage tanks, compressor stations)
• Downstream facilities (e.g., refineries, chemical plants)

In addition to its presence in industrial operations, benzene may be released through incomplete combustion of fossil fuels, tobacco smoke, and other anthropogenic sources. Its mobility in air, water, and soil contributes to environmental dispersion raising concern for airborne exposure, groundwater contamination, and soil pollution near production an processing sites.
