TOCAM Portable Micro Gas Chromatograph GC VOCs Air Monitoring

TOCAM™ (Toxic Organic Chemical Air Monitor)
Portable Micro Gas Chromatograph GC with Photoionization Detector
Volatile Organic Compound (VOC) Analysis for Air Monitoring

TOCAM Portable Micro Gas Chromatograph GC VOCs Air Monitoring


The TOCAM uses a photoionization detector (PID) and helps customers quickly determine Total Volatile Organic Compound (VOC) and Single Volatile Organic Compound concentrations down to part-per-billion levels, delivering results in under 10 minutes.

The TOCAM portable gas chromatograph GC is very lightweight, weighing about 2.5 lbs, which makes it convenient to take out into the field for your air sampling needs.

Additionally, the TOCAM has a mounting bracket, and can be mounted inside a vehicle with a sampling port to screen many areas for VOCs.

What Can the TOCAM™ Do?2020-02-05T20:40:15+00:00

The TOCAM Portable Micro GC Gas Chromatograph can quickly and directly measure total and specific VOCs in air using two different modes:


TOCAM in the field Portable Gas Chromatograph GC

In Rapid Survey Mode the TOCAM measures Total VOC concentrations.

The TOCAM has an audible alarm that will sound when a set concentration of Total VOCs is detected. The TOCAM can also be set to have a certain concentration of Total VOCs trigger a full GC analysis to help determine what VOCs are contributing to the total VOC detection.


FROG Portable Gas Chromatograph GC - On its own

In Full GC Analysis Mode, the TOCAM measures individual VOCs including contaminants of concern.

This mode gives individual compound concentrations.

  • Environmental Monitoring and Remediation
  • Mobile Outdoor Air Quality Measurements: The TOCAM can be mounted inside a vehicle with a sampling port to screen many areas for VOCs
  • Industrial Hygiene Air Sampling
  • Landfill Gas Monitoring
  • Indoor Air Quality
  • Vapor Intrusion: The TOCAM can detect many compounds in part-per-billion (ppb) levels and even sub ppb levels, making it ideal for vapor intrusion.
  • Process Monitoring
  • Soil Gas
  • Soil Vapor Extraction
  • Benzene Waste Operations NESHAP (BWON): The TOCAM can quickly and specifically measure Benzene in air.
