Benzene Sampler

AI-106

Intro:

Benzene is found in the air from emissions from burning coal and oil, gasoline service stations, and motor vehicle exhaust and from industry producing or using it. These sources contribute to elevated levels of benzene in the ambient air, which may subsequently be breathed by the public. EPA has classified benzene as known human carcinogen for all routes of exposure.

Our Benzene Sampler AI-106 is used for collection of samples of Benzene and other VOC’s in ambient air. The organic compounds are collected from ambient air by adsorption on an activated charcoal column. The organics are then desorbed and analysed via a Gas Chromatograph to estimate its actual concentration. Designed with the best engineering approach, the E&E Solutions made Benzene Sampler comes along with an inbuilt differential pressure and velocity meter. The sampler is battery operated for uninterrupted usage and has a flow meter in the range of 20 – 200 ml/min. Provision for low flow control allows the instrument to collect a representative sample over several hours without fear of sample loss due to saturation or breakthrough in the adsorbing column.

 

Features:

  • Portable, battery operated instrument with easy user interface.
  • Flow meter provides accurate flow reading in the 20 to 200 ml/min flow range.
  • Flow meter provides total volume of air sampled in litres.
  • Upon full charge the rechargeable Lithium Ion battery pack allows operation for at least 8 hours.
  • Oil-free pump provides low noise and requires little maintenance.
  • Can be used for monitoring a wide variety of organic compounds.
  • Programmable Microcontroller base Timer allows operation in cyclic manner for composite sampling.
  • Instrument comes along with charger for battery charging and one activated charcoal filled tube. 

Technical specifications:

  • Flow Meter: Rotameter with least count of 10ml/minute and adjustable flow rate.
  • Flow Rate Range: 20ml per minute to 200ml per minute.
  • Timer: Microcontroller based timer allows user programmable timing for start/stop of pump.
  • Battery: Rechargeable Li-ion battery with run time of 8 hours.
  • Pressure: Inbuilt differential pressure meter for precise digital pressure readings.
  • Sampling Media: Activated charcoal tubes is used as adsorbing media.
  • Filter media: Glass fibre filter paper of 25mm Diameter along with filter holder can be used to separate unwanted dust from the air to be sampled.
