Measurement of APHA color either on-line or in a laboratory setting using a photometer. Background: APHA is sometimes referred to as the Platinum Cobalt (Pt/Co) or Hazen scale. Also referred to as a “yellowness index”, the APHA color scale is a common method of comparison of the intensity of yellow-tinted samples to assess the quality of liquids that are clear to yellowish in color. Originally developed to determine the purity of municipal water supplies, it is now used as a metric for purity in the water,...

The nation has stockpiled thousands of cylinders and canisters of toxic and deadly chemical weapon agents, including mustard gas (HD), sarin (GB), tabun (GA), and V-agents. Most of these CWAs are stored at DOD facilities around the country and many have been in storage for years and years. As a consequence, DOD requirements specify that the stockpiles have to be monitored regularly for leakages to prevent release to the environment and exposure to personnel.

Manufacturing of powdered and liquid flavorings and fragrances involves production phases where flavoring chemicals may be released into the ambient air breathed by workers. Exposure control by gas analyzers in the production rooms and laboratories is necessary to ensure that the Time-Weighted Average (TWA) concentrations do not exceed the maximum Permissible Emission Limit (PEL) values.

Typical modern printing processes utilize solvent-based dyes. The evaporation of the dye solvents into the ambient air during the printing process may expose the workers to various chemicals. Depending on the type of solvents in case, the solvents have different long term exposure limits, which should be obeyed. Component specific measurements are necessary to protect the workers from exposure while avoiding unnecessary interruptions to the printing process from false alarms.

Diseases related to contamination of drinking water constitute a major burden on human health. The manufacturing, processing and distribution of safe water throughout the water cycle will raise the need for efficient monitoring systems detecting in real-time contamination, be it chemical or biological. Infectious diseases caused by pathogenic bacteria and parasites are the most common and widespread health risk associated with drinking-water. A number of chemical contaminants have been shown to cause adverse...

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...

HI-Q considers the responsibility for worker health and safety to be of paramount importance. This is a responsibility that requires good documentation of facts. Many studies are conducted to evaluate workplace health and safety conditions as they relate to workers exposure to radiation, chemicals, and biological hazards during the normal work day. HI-Qs wide line of air sampling equipment, systems and accessories are used in the monitoring then documentation of these workplaces.

The measurement of occupational exposure to pollutants in the operating room is an essential tool for the detection of chemical, linked not only to the occurrence of infections and various diseases, but also to reduced alertness and performance of staff. To meet the above requirements, ETG proposes the use of ‘INFRARUN, thanks to the high sensitivity and stability and the very wide dynamic range, INFRARUN is the ideal tool to make a continuous sampling in the short and long-term gaseous contaminants in the...
