The analysis of soil, sediment, coal, mine tailings or other geological solids for trace metals can provide valuable information on industrial process optimization, human health and other environmental risk assessments, or the development of remediation strategies. In many cases, the measurement of trace metals in various materials requires not only an understanding of the total concentration but also a more complete understanding of the type and concentration of specific compounds present at a site. 

We have developed a variety of innovative methods to determine trace metals in various forms within geological solid materials. No matter what material or application, we can supply you with a profile of the trace element of interest and a better understanding of its potential effect.

The methods for measuring metals, mercury and mercury species in crude oil and gas condensates are limited as there are only a few laboratories that have the instrumentation and detection limits which are not part of routine analytical methods.

Crude Oil, Condensates, Frac Waters, Fuel Products
