  • Sample preparation is the key to quality analysis with a laser analyser

    Sample preparation is the most important step of any chemical analysis. To get the best results with any elemental alloy analyser regardless of the technology, the sample must be clean before taking a measurement. Otherwise the results are always compromised at least to some extent. The effect of dirty surfaces will vary and some technologies are more forgiving to sample surface conditions than ...

  • 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 ...

  • Detection of atrazine, alachlor, cyanazine and metolachlor in corn

  • Optical Polishing

    A mid-western firm who manufactures a large amount of specialty eyeglass lens was having a problem removing lead from their wastewater stream. This stream was a combination of the grinding effluent waster and the wash stream containing cleaning compounds. The normal effluent stream had a pH of 11- 11.5. The sample was treated without pH adjustment with the addition of Floccin-HP. The dosage was ...

  • Precellys application focus forensic - case study

    Forensic laboratories working with hard samples such as hair [1, 2J, bone [3], teeth, skin, etc. experience difficulties with DNA extraction due to the high energy needed to grind these tissues. Moreover, biological evidence is available in small quantities and the current techniques used do not provide high quality results. The Precellys homogenizers provides high speed sample disruption based ...

  • Cadmium and lead removal from municipal landfill leachate using carbon adsorbent made from oil palm shell

    This paper focused on adsorption process for metals removal from landfill leachate using oil palm shell as adsorbent. Raw shells were grinded to sizes of about 2 mm, followed by heating in at 420°C for a period of 4 hours. Batch test indicated a removal of more than 60% Cd and Pb from leachate samples. The removal process agrees with the Freundlich isotherm model. Column test for continuous flow ...

  • Comparing Field Portable X-Ray Fluorescence (XRF) To Laboratory Analysis Of Heavy Metals In Soil

    ABSTRACT Field portable x-ray fluorescence (XRF) continues to gain acceptance as a complement to traditional laboratory testing of metal contaminated soil. The quality of data produced by field XRF varies with site conditions, soil composition, and sample preparation. Quality assurance protocols for the field method usually require that a number of field samples be split and sent to a ...
