VOCAM™ (Volatile Organic Chemical Air Monitor)
Portable GC PID, Gas Chromatograph with Photoionization Detector
for Detecting Volatile Organic Compound (VOCs) in Air

VOCAM Portable GC PID Gas Chromatograph Photoionization Detector in Air


The VOCAM™ can detect volatile organic compounds (VOCs) in air delivering lab-quality results in less than 10 minutes. It is a high-resolution GC system specifically designed for remote monitoring.

The VOCAM™ GC will detect chemicals in addition to semi-volatile organic compounds such as naphthalene. It can detect VOCs at sub-part-per-billion levels or at high part-per-million levels depending on its configuration.

The VOCAM™ is highly customizable. The OEM unit can be integrated into your own system and/or you can purchase the fully integrated system in an enclosure, as shown.

Offering this type of customization allows the VOCAM™ to suit a variety of applications. VOCAM™ operators can use it to determine trace amounts of suspected benzene at hydraulic fracturing sites or at refinery fence-lines while the results are reported to the web. Other applications include using VOCAM to monitor worker exposure to solvents used in the workplace. This is all done without waiting for results from an offsite lab.

How to Use the VOCAM2020-10-22T15:52:51+00:00


VOCAM Portable Gas Chromatograph GC PID - With a computer

You can initiate an analysis on the VOCAM™ portable GC using a computer. Attaching the VOCAM™ to a computer allows data to be studied in real-time with the Ellvin™ chromatography software.


FROG Portable Gas Chromatograph GC PID - Over the internet

You can use the VOCAM™ portable GC over the internet via a cellular modem.

Pictured above is the VOCAM™ deployed at Defiant Technologies, where it is powered by solar charged batteries for continuous operation.


If you have your own communications platform, Defiant can work with you to make VOCAM™ work on your network for your customers.

Integrators are encouraged to contact Defiant regarding the VOCAM™, our small portable GC system.
