  • Life Among The Heavy Metals

    Authors in scientific and applied works interpret the meaning of the concept "heavy metals" in different ways. Today, they include more than 40 chemical elements with an atomic mass of more than 50 atomic units. An important role in the determination of heavy metals is played by the following conditions: their high toxicity in relatively low concentrations, and the ability to bioaccumulation. ...

  • Field demonstration of a near-real-time multi-metals ambient fence line monitor case study

    National emissions standards for hazardous air pollutants (HAPs) are required under Section 112 of the Clean Air Act to limit the release of specified HAPs. Permitting, monitoring and enforcement of these emission limits are an integral part of managing air quality to protect human health and the environment. However, this is difficult and highly uncertain in the case of fugitive emissions ...

  • Guide for developing a multi-metals, Fence-line monitoring plan for fugitive emissions using x-ray based Monitorsa case study

    Airborne metals and metal compounds are of particular concern to human health. Not only are they included in the United States (U.S.) Environmental Protection Agency’s (EPA) list of 187 hazardous air pollutants (HAPs), they represent 8 of the 33 urban pollutants identified by the EPA as posing the greatest potential health threat in urban areas. This is particularly significant since 80% of ...

  • Oil Sampling Best Practices

    Obtaining a representative oil sample from a closed loop lubrication system is essential to any good oil analysis program. As oil analysis programs become more standardized for routine monitoring, especially within equipment warranty support programs, equipment makers provide more sampling points on new equipment. These ...

  • Instrumentation and Operational Considerations for On-Line pH Measurement in Samples Below 10µS/cm Conductivity

    Ordinarily pH measurements are made in water with 1,000 to 10,000 µS/cm conductivity. The conductivity comes from dissolved solids which are typically salts but also acid or base. These dissolved substances are in the solution in ion form which makes such solutions conducting. With conductivities of 1,000 µS/ cm or more, an ample supply of mobile ions provides pH electrodes with a ...

  • White Paper: ANSI N13.1-2011 Stack Sampling Considerations

    Background Nuclear facilities are required to follow industry standards for sampling stack effluents. Exposure of the general public to released radionuclides must be monitored as specified in US governmental regulations. The United States Environmental Protection Agency (USEPA) and the United States Nuclear Regulatory Commission (USNRC) have the authority over the monitoring of these ...

  • Case study - Low-flow groundwater sampling on a nuclear site

    Nuclear licensed site use of low-flow groundwater sampling shows: Reduced time, reduced quantity of purge water – both thus reducing cost - and reduced risk of operator contact especially with potentially radioactive-contaminated purge water thanks to a self-contained enclosed system. One of the biggest headaches on site is the purge water and the expense of getting rid of it – after ...

  • How can I keep my samples secure and tamper proof?

    The first stage of any test is to collect a sample. Whether it’s water, biological tissues, or a sample from a production line, it must be representative of the bulk and not be altered in order to give accurate results. Most samples will have to be transported after they are collected – this might be just a few meters from a production line to the test room, or could be ...

  • U.S. troops get boost from soil sampling equipment supplier

    Top of the line soil sampling equipment isn’t the only thing that AMS produces. They also produce smiles on the faces of United States Troops overseas. The holidays can be lonely for U.S. troops, but it can also be immensely joyful when they know they have love and support from back home; not just from friends and family, but from complete strangers.  Rick Vollweiler, ...

  • The 75-year history of soil sampling equipment supplier, AMS

    Almost 75 years ago in the small town of American Falls, Idaho, a man had a dream and a vision. Art Vollweiler had the philosophy that “everything was a work of Art.” Associating his name with everything he created meant something in 1942. It meant that everything he designed and built was made to last. Art’s assurance in quality has stood the test of time, and continues to be ...

  • Sample Handling Strategies for Accurate Lead-In-Soil Measurements in the Field and Laboratory

    ABSTRACT The inhomogenous lead-in-soil matrix can present serious obstacles to accurate sample collection and handling. In typical lead-in-soil measurement, particle size related errors in sampling and sample handling often exceed all other sources of error. The magnitude of error can vary widely depending on the particulate nature of the lead contaminant and the effectiveness of control ...
