Track Total VOCs Instantly With the AQS-1 Volatile Organic Compound Monitor

volatile organic compounds testing

Accurately monitoring air quality is essential for protecting nearby communities from potentially harmful airborne compounds. At AirLogics, we’ve engineered the AQS-1 with the flexibility, precision, and speed needed for effective environmental monitoring. Our volatile organic compound (Total VOCs) monitor provides real-time readings, empowering teams to identify and respond quickly to elevated Total VOC levels affecting off-site receptors.

Compact Power with Real-Time Accuracy

The AQS-1 is designed to work in real environments, where rapid detection of Total VOCs is essential. With an integrated photoionization detector (PID), the system quantifies VOCs such as benzene and toluene every minute. Unlike many basic sensors, the AQS-1 applies a proprietary scrubber system, alternating between filtered and unfiltered air samples. This helps remove the influence of ambient humidity—a common flaw in traditional PID readings.

Our system is not only built to deliver immediate VOC data but also includes available modules for PM2.5, PM10, TSP, H₂S, NO₂, O₃, and noise levels. The inclusion of gravimetric sampling and a true pumped sampling system means consistent airflow and sensor protection, resulting in longer equipment life and more dependable results.

Why Pumped Sampling Makes a Difference

Most compact sensors rely on passive airflow, which can result in uneven sampling and inconsistent readings. AQS-1 addresses this with a pumped system, ensuring a controlled flow of ambient air. This provides uniform exposure to the VOC module while enabling the use of particulate filters. It’s a smarter design for field monitoring where stability matters.

The pump-driven design also supports better maintenance of the sensor baseline through Automatic Baseline Correction (ABC). Recalibration takes place every 60 seconds, automatically offsetting for sensor drift and reducing error caused by interfering gases. This is one of the most important features that separates the AQS-1 from less sophisticated tools.

Rugged, Modular, and Ready for the Field

AirLogics developed the AQS-1 for users who need reliability without being tied down by bulk or complicated setup. The unit is lightweight, with options for solar, lithium battery, or AC power sources. Field teams can deploy it quickly and keep it running efficiently even in remote locations.

Each AQS-1 comes with field and factory calibration using high-purity gas standards traceable to national reference materials. This ensures accurate data from the moment of deployment through extended operation. The nephelometer used in the PM module, custom-built by Met One Instruments, has a proven track record for performance and durability under real-world conditions. Unlike budget optical counters, this hardware delivers consistent results year after year.

Custom-Tuned Monitoring for Local Impact

At AirLogics, our monitoring focus is straightforward—support clients in assessing air quality conditions at off-site receptor locations. Our approach is purpose-built to inform site-specific strategies, providing precise readings in areas that require careful environmental attention. This includes construction sites, remediation sites, and other spaces where emissions may impact surrounding neighborhoods or public areas.

Real-World Value in Every Reading

The VOC module in the AQS-1 is sensitive to a wide range of volatile organics and is calibrated typically to isobutylene. The signal is converted through a proprietary algorithm into VOC concentrations, output every minute. This enables stakeholders to take immediate action based on trustworthy data—without waiting for lab reports or lengthy processing.

This fast feedback loop helps address potential air quality concerns before they escalate. And thanks to the AQS-1’s modular structure, teams can add or remove sensors based on project needs without replacing the entire system.
