  • 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 ...

  • Case study - RTO handles high VOC loading at silgan containers

    OVERVIEW Regeneration Game - Originally printed in The Canmaker Magazine - Sayers Publishing Group As the first generation of oxidizer systems in the industry nears the end of their service life, many canmaking plants face repair or replacement of their existing air pollution control systems.
