As Horizon Technology continues to grow and our involvement internationally increases, we have developed methods which comply with regulatory agencies other than the EPA. This page contains Application Notes developed with the assistance of laboratories located outside of the United States.
Analysis of PFAS Specified in EPA Method 537 and Beyond using Shimadzu UFMS
This application note demonstrates the use, performance, and compatibility of Shimadzu ultra-fast mass spectrometry for EPA Method 537 with an expanded compound panel of seven additional PFAS. A total of 27 PFAS were extracted, separated and detected with triple quadrupole mass spectrometers, LCMS-8045 and LCMS-8050. Recoveries of 86-106% (LCMS-8050) and 77-104% (LCMS-8045) were well within the limits outlined in EPA 537. Method detection limits of 0.7-1.7 ng/L (ppt) and 0.7-3.3 ng/L were obtained and both...
Moscow snow reveals new air pollutants
GC-MS analysis of Moscow snow reveals new pollutants in the city air. Cities, with their traffic, industrial centers and factories, usually suffer from some degree of air pollution. Moscow, which houses all of these as well as power plants and an oil refinery, is no different. Regular monitoring of environmental pollutants is common practice in many cities and priority pollutants are detected and monitored. However, due to social and economic changes, which all cities are subject to, the environment within...
Quit wasting time in wastewater filtration
Susan takes pride in the work she does each day. After all, without her expertise in the lab, the plants and animals that live in and around her community’s waterways could suffer. Susan is a Lab Manager at a wastewater treatment plant working in a specialized laboratory that tests wastewater samples, or effluent, which originates from industrial plants or domestic sewage. The sample filtration tests performed by her team are required to meet federal regulatory standards at wastewater treatment plants like...
EPA Compliant Due to Sufficient Solvent Recovery - Case Study
Customer: Con-Test Analytical Laboratories, USACon-Test Analytical Laboratory provides environmental and hygiene analytical services with the capability of analyzing nearly all water, air, soil, and solid materials.Application: US EPA 608US EPA Method 608 covers the determination of certain organochlorine pesticides found in industrial waste water. The sample is first extracted with methylene chloride, concentrated to 1 mL and analyzed by GC/MS instrumentation. The concentration step is paramount and must be done...
On-Line Fast Analysis of AMC from ppt to % levels in Clean Air Room
To ensure people’s safety and a good repeatability of industrial process, near real-time risk management and the continuous monitoring are crucial. In the semiconductor fabrication process, particle control is an essential part. Clean room technology, which relies on the use of HEPA and ULPA filtration, has in the past exclusively focused on the control of micro- and nano-particles. Nevertheless, as a consequence of device reduction, Airborne Molecular Contaminations (AMCs) has also become a key detractor...
