Assay Technology had its origin in 1981 in a small garage lab in Silicon Valley where some of us pondered how to monitor personal exposure to chemicals. With “cost-effective & convenient” as our mantra, we sought to replace inconvenient pumps and hazardous glass tubes with much smaller personal samplers that would not disrupt work and would promote ease of analysis. During the 1980s and ’90s, the industrial hygiene community (including OSHA & NIOSH) seemed skeptical that cost-effective and convenient badges could out-perform the traditional, cumbersome pump-and-tube methods. At the same time, the health care industry were early adopters of Assay’s personal sampling badges and helped us to establish our business model, which is still to integrate the most cost-effective, convenient products with seamless customer service. In the 21st century, as personal monitoring badges have become dominant in vapor sampling, Assay continues to provide a product that is smaller, more convenient, and more cost-effective than competitors.

Miller-Nelson Research

The historic Miller-Nelson lab provides chemical capacity testing for respirator cartridges, filters, and other sorbent media.

We participate in technological developments that relate to personal chemical monitoring, evaluating chemical protective devices, and the accurate generation of chemical test atmospheres. More…
