Key considerations include the type of media, pressure and temperature ratings, flow control requirements, and actuation method (pneumatic, electric, or hydraulic). Additionally, compatibility with existing control systems, response time, and maintenance accessibility play a crucial role in ensuring optimal performance and reliability in automated operations. ...
In 2005, the United States Environmental Protection Agency (US EPA) issued a method regarding the use of field - portable XRF spectrometers for soil and sediment analysis. ...
CMTA International and the OSEI Corporation performed a trial to remediate PFAS contaminated soil using our technology Oil Spill Eater II (OSE II). The PFAS contaminated soil was provided by an Australian Federal Government Department for the purpose of CMTA and the OSEI Corporation to perform its own trial to demonstrate how effective OSEII is at remediating PFAS contaminated soil. The trial ...
The US Environment Protection Agency acted upon issues raised by indigenous tribes in Washington and Oregon, and other groups about the instances of Coho salmon young being killed off by the presence of 6PPDq in the rivers. In November 2023, the EPA committed to gather evidence to be used to create regluations. The U.S. EPA has now announced the publication of a ...

Per- and polyfluorinated alkyl substances (PFASs) are the class of almost 10,000 manmade organofluorine compounds more commonly known as «forever chemicals». PFASs are resistant to water, oil, and heat. Due to their unique properties, they find widespread applications in many products and industries. They can enter the water supply and the food chain, causing various health problems ...
Each rack can digest up to 12 samples in Quartz or Teflon® vessels with the same or 12 different methods. Completely redesigned with new hardware, software, and a 15” color touch screen – create or choose your digestion method and monitor, control, and save each sample profile at your fingertips. ...
Chromatotec presents a headspace sampling system (following US EPA method 502-2) designed to extract representative samples from a liquid phase. ...
UV Photometric-based O3 gas instruments are the most widely used in the US EPA national regulatory air monitoring network, with approximately 1,300 instruments currently reporting data for regulatory compliance throughout the U.S. ...
Environmental Protection Agency Method 557 (EPA 557). The new Thermo Scientific Disinfection By-Products (HAAs) Application Workflow uses the Thermo Scientific Dionex ICS-6000 HPIC system and a Thermo Scientific Dionex IonPac AS31 column coupled with triple quadrupole mass spectrometry, to deliver a fast, sensitive and simple method, that has ...
"Environmental laboratories rely on IC technology to undertake anion analyses in line with the Environmental Protection Agency (EPA) Method 300, while academic settings commonly use these foundational IC systems for teaching purposes," said Dino Alfano, vice president and general manager, ion chromatography and sample preparation, Thermo Fisher Scientific. ...
Catalytic Products International (CPI) installed a Regenerative Thermal Oxidizer (RTO) at a Midwest USA candy manufacturer for the abatement of Volatile Organic Compounds (VOCs). The TRITON 6,000 SCFM Regenerative Thermal Oxidizer (RTO) will control heptane emissions from several lines. The VOCs are emitted at the load cell weighing tanks and at the mixing kettle of each kitchen skid. The RTO ...
Consistent with PRIA 4, EPA is implementing changes related only to the AEZ requirements in the WPS. ...
These laboratory testing methods act as a foundation for EPA’s interim guidance to registrants regarding residual effectiveness. While EPA does not have an approved standard method to support virus claims for these types of products, EPA states that the following information is intended to provide interim ...
As most know, EPA has not before now provided guidance on how stakeholders can demonstrate to EPA’s satisfaction that their product remains efficacious for periods of time, given the broad diversity of contact opportunities and scenarios. ...
The system's simple design requires no additional pumps or equipment—enabling users of all skill-levels the ability to run routine IC methods. "For laboratories who are used to traditional wet chemistry methods with labor-intense workflows and time-consuming maintenance needs, ion analysis of water can be complex, often making this type of analysis ...
This new guidance provides expedited procedures for those registrants that wish to add electrostatic application methods to their disinfectant product labels. The Guidance outlines information that EPA asks registrants to submit to obtain expedited review of their proposed addition of this application method to their labels. ...
According to EPA, data generated by EPA researchers will inform any regulatory decisions (including the approval and use of these products according to the label) made as part of the pesticide registration process through EPA’s Office of Pesticide Programs. EPA researchers are also evaluating other possible high-efficiency ...
Several different samplers were investigated in the method, including the radial DSD-DNPH sampler. At the time, the radiello® Aldehyde sampler was not available in the United States for inclusion in the method. ...
