This monitor is suited for compounds for which activated carbon shows limited capacity. Accuracy of +/-25% at a 95% confidence level for many workplace contaminants. Bulk packed. Analysis not included.
The 3M™ Organic Vapor Monitor 3520, with Backup Section uses the proven scientific principle of diffusion, which is the gradual mixing of molecules of two or more substances. Primary and back-up sorbent pads are included for sampling demanding environments where additional capacity is needed. Especially suited for monitoring compounds like acrylonitrile, butadiene and methylene chloride for which activated carbon shows limited capacity. Increased sampling may be necessary when sampling volatile compounds (compounds with low boiling points) , high or unknown concentrations, complex mixtures, or when sampling in high humidity conditions. It has an 18-month shelf life.
