Compliance with the ASTM method at low concentrations sulfur. Sulfur is a major element of importance because it forms sulfuric acid in the atmosphere when burned and has harmful impact on the human health and on the environment. In the mid-2000`s, the Environmental Protection Agency (EPA) began a program to greatly reduce the amount of Sulfur in petroleum products. The current allowable sulfur limit in vehicle fuel is 15 ppm (parts per million). To reduce the pollution coming from vessels the international maritime Organization (IMO) established new limits on emission of sulfur oxides. In Emission Controlled Areas the sulfur limit will be 0.1 % starting 2015. The continued strategy by EPA and IMO to reduce the amount of sulfur in petroleum products put a great demand on sulfur monitoring in fuel and oil products.

Hydrogen Fluoride (HF) is a very useful chemical used in a variety of industries. However, HF is highly toxic with potential fatal consequences with exposure to humans, so facilities that make or use HF should exercise great care. Nevertheless, there is always the risk of leaks from process elements such as valves, pump seals and storage vessels. Tanker loading, transporting and unloading operations also provide opportunity for HF releases. Industrial processes that make or use HF typically have arrays of point sensors distributed throughout the unit. However, these sensors are maintenance intensive and have relatively slow response times. In addition, a point sensor will not detect an HF release unless it is located directly in the area of that release. Electrochemical HF sensors also respond to chlorine, ammonia, and sulfur dioxide, resulting in false alarms.
