  • Small Diameter Piston Sampling with Cone Penetrometer Equipment

    A small diameter piston sampler that can be operated by a cone penetrometer rig has been developed specifically for recovery of sand and clay samples under conditions where sample recovery using ordinary means is difficult. The 22-mm-diameter sample that is recovered in a polythene sheath is valuable for visual examination of the soil rather than for most laboratory testing purposes. Provided the ...

  • Sampling moisture in the soil profile

    Patterns of water replenishment and use give rise to large spatial variations in soil moisture over the depth of the soil profile. Accurate measurements of profile water content are therefore the basis of any water budget study. When monitored accurately, profile measurements show the rates of water use, amounts of deep percolation, and amounts of water stored for plant use.Experimental ...

  • A Remote Automated Optical Field Sampling System based on the UniSpec-DC equipped with a Wireless System

    For remote locations, a reliable and repeatable field sampling method is needed for monitoring ecosystem processes for various scientific reasons (e.g. ground truthing, link vegetation indices to ecophysiological variables) (Claudio et al., in press; Fuentes et al., in press, Cheng et al., in press). To ensure that the data are collected continuously, and to collect the data during severe weather ...

  • Will the equipment match the regulatory method?

    Anyone involved in field analysis of oil in water will con tinually get the question "Does your equipment match the regulatory method?" Zj While the amount of oil in water is highly regulated, it can also be a challenging measurement. It is complicated by the fact that oil comes in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the regulatory ...

  • Setting the standards for headspace sampling by PID

    The responsiveness of PIDs to virtually all VOCs has seen them become the accepted tool for initial site entry assessment, ensuring optimal detection of unknown and often toxic or hazardous chemicals found at hazardous waste sites and chemical emergencies. The speed and accuracy of modern PID equipment means that many worker and community safety concerns during initial and ongoing operations can ...

  • Impact of Corrosion on Electronic Equipment

    Corrosion is the destruction of metals through reaction with compounds in their environment. It is a natural process because compounds such as oxides, sulphides and chlorides are formed and these are stabler than pure metals. Electronic circuits and components are omnipresent in our environment. Until recently, the thousands of soldered joints that an electronic circuit contains were ...

In the UK there are over 12 manufacturers and distributors offering CEMS (continuous emissions monitoring systems) using a variety of technologies including UV and IR absorption, FTIR, DOAS, chemiluminescence and photoacoustic spectroscopy (PAS). The majority of CEMS ...

  • Using FIMS to determine mercury content in sewage sludge, sediment and soil samples

    Tim Flow Injection Mercury System (FIMS) is a dedicated system that integrates flow injection mercury cold vapor generation with a very sensitive detector. The exceptional system stability and the long path measurement cell provide instrumental detection limits as low as 5 ng/L using a sample volume of 5(H) jxL. The improved sensitivity of the FIMS permits sample dilution, therefore reducing the ...

  • 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 ...

  • Sampling and On-Site Analytical Methods for Volatiles in Soil and Groundwater - Field Guidance Manual

    Abstract: Volatile organic compounds (VOCs) are among the most frequently identified contaminants in soil and groundwater samples obtained during the investigation of suspected hazardous waste sites. Because some VOCs and their degradation products are potentially mutagenic, carcinogenic, or teratogenic, their concentrations in these two matrices are key factors in the risk assessment process. ...
