  • What is the difference between Rotary Vane and Diaphragm vacuum pumps?

    Most laboratories will have a vacuum pump. They are widely used across labs of all disciplines for a range of tasks from basic filtrations or evacuating a desiccator right up to use with large equipment such as vacuum ovens or rotary evaporators. The two most common types are rotary vane or diaphragm pumps – but ...

  • Vaccu.Lan for Green

    You're building a 'green' science building, and some of your laboratories require vacuum support. How do you provide vacuum for those labs? You can't use an oil-sealed rotary vane vacuum pumps in the labs. The oil mist would contaminate the laboratory air, and the noise pollution makes the working environment unpleasant. The pump oil would quickly be contaminated by biological and chemical ...

  • Analysis of TNT and RDX in groundwater

    MATRIX: Water ANALYTE: TNT and RDX LIMIT OF DETECTION: TNT 1 ppb (mg/L), RDX: 5 ppb (mg/L) BACKGROUND: This application describes a field screening method for determining TNT and RDX concentrations in water. The method uses solid phase extraction to remove and preconcentrate the analytes from water. In the method, a 2 ...


  • Evaporator concentrates brine pond for about 1 cent per gallon

    The Facility Eagle-Picher Industries has an 8-acre hazardous waste surface impoundment pond at its Electro-Optics Division plant in Quapaw, Oklahoma. The Problem By the time Eagle-Picher contacted Aqua-Chem ICD, the impoundment pond had been in use for more than 20 years and contained more than 5 million gallons. Environmental regulation required the plant ...

  • Common Treatment Technologies for Inorganics in Ground Water, Surface Water, and Leachate

    It may be necessary to know other subsurface information to remediate inorganics in ground water, surface water, and leachate. Treatability studies are usually necessary to ensure that the contaminated ground water can be treated effectively at the design flow. A subsurface geologic characterization would be particularly important to characterize the effects of adsorption and other processes of ...

  • Enhanced Anaerobic Bioremediation of a TCE Source at the Tarheel Army Missile Plant Using EOS

    EOS, or emulsified oil substrate, was used to stimulate anaerobic biodegradation of trichloroethene (TCE) and tetrachloroethene (PCE) at a former Army-owned manufacturing facility located in the Piedmont area of North Carolina. Previous use of chlorinated solvents at the facility resulted in soil and groundwater impacts. Ten years of active remediation utilizing soil vacuum extraction and air ...

  • Glyphosate (roundup) and AMPA analysis in crops method abstracts

    The recently practiced method1 for analysis of Glyphosate and AMPA in crops suffers from an expensive, time consuming cleanup procedure that has less than ideal recoveries. Although the analysis (after clean up) by ion-exchange chromatography with post-column derivatization is rugged and sensitive, a new method was sought to improve the sample preparation. This resulted in AOAC Method 2000.522 ...
