How it Works
UV-DOAS Technology
Within each Cerex UV3000 analyzer, a gas sample is drawn in and measured in a fiber coupled external cell connected to a process stream, or via an optional sample pump.
A miniature spectrometer then collects the gas fingerprint data, and Cerex’s proprietary software compares the results to a calibrated reference, or “library spectra”.
Ultimately, an onboard or external PC reports reliable real‐time concentration data up to once per second, and stores all spectral data for later post processing or archiving.
The result is near real-time spectral “fingerprints” of all target compounds, with accurate qualitative and quantifiable data of each.
How is this possible? A physics principle known as the Beer-Lambert Law. UV radiation that passes through a gas will “absorb” the gas; thus, when viewed on a spectrograph, a distinct pattern of absorption appears. Each gas has a unique “absorption pattern”, and this, combined with our proprietary photometric Differential Optical Absorption Spectroscopy (DOAS) algorithm, Cerex UV-DOAS analyzers are able to quickly and accurately identify compounds from an air mixture without the need to calibrate or take a clean air background.
Why UV-DOAS?
Ultraviolet spectroscopy principles are similar to common infrared methods, but offer lower detection capability for many chemicals associated with impact on human health. We recommend UV-DOAS based analyzers for a faster, more accurate, and less costly solution for certain compounds and applications.
Common Detectable Gases
Ultra Low Detection Limits
The Cerex Hound Series has as low as parts-per-billion minimum detection limits and wide dynamic ranges, allowing earlier and more thorough detection of gases than traditional sensor arrays. In comparison to outdated technologies, UV3000 series analyzers feature multi-gas monitoring of individual species, lower detection limits, no water vapor interference, inherent calibration and no sensors to poison.
Inherent Calibration
The system can be span checked at any time, however, the measurement and analysis method employed in this system has the true calibration inherent in the fixed library references. Unless there is a system fault, calibration is never needed. The system is self‐compensating for all normal sources of drift found in analyzers including temperature, aging of the lamp, degradation of the optics, etc.
Targeted Library for Increased Value and Cost-Effectiveness
Cerex UV3000 analyzers include a multi-purpose standard library suitable for monitoring dozens of compounds. Custom calibrations are available based on application.

Software
Results You Can Rely On
Cerex recognizes that detailed gas monitoring results need to be reliable and available quickly to various stakeholders. Consequently, Cerex engineers developed software to accurately detect and display gases within the air, in real-time, from any location.
On a Cerex UV3000 analyzer, a user can see results on the analyzer itself, or remotely via a phone, tablet, or computer anywhere in the world via a virtual connection. GPS and cellular configurations make this possible in isolated environments.
All data is automatically saved in an easy to access .csv file; this feature helps our clients in various ways - from daily use to crucial events such as evidence in court. Early detection translates into quicker response times, reduced environmental impact, decreased plant downtime, and reduced exposure to site personnel and the community.
Real time spectral subtraction and synthetic background implementation allow the UV Hound and Micro Hound to clearly display accurate concentrations of target gases over 1000 meters without interference from other gas species
