Method 0031 : VOC
Volatile Organic Sampling System
VOC Sampling made easy for stack emissions
Volatile Organic Sampling System (VOSS) comprising an operating panel and a VOC sampling train facilitates sampling for volatile organic compounds from an industrial stack.
Available Model : PEM - VOSS 1
The Volatile Organic Sampling System has been designed for sampling Volatile Organic Compounds from stack emission at low flow rate as per US EPA Sampling procedure described in Method 0031. The samples are later desorbed using thermal desorption (5041A) and analyzed by GC/MS (Method 8260B).
Applications :
- Stack emission monitoring for VOCs
- Compliance monitoring services
- ISO 9001,14001,180001 Audit Compliance
- Factory Act Compliance
- Common industries for VOC monitoring are Chemical, Paint, solid waste incinerators etc.
Physical Design Highlights
The sampling system consists of a heated glass lined sampling probe, heated Teflon sampling tube, VOC Sampling train and VOC Sampling measurement module complete with necessary accessories. The material of construction in contact with the sample gas is only glass & Teflon. The sampling train consists of condensers, glass sampling tubes for Tenax / Tenax / Anasorb 747, Condensate Tube & Silica Gel Adsorber.
Salient Features :
- Complies with the requirements of method 0031 of US EPA.
- All parts in contact with the sample gas made only of Glass / PTFE
- Electronic temperature control.
- Easy to set up and simple to operate.
