  • Digestion of Trace Metals in Wastewater Using DEENA, an Automated Sample Digestion System
    methods 200.7 and 200.8. EPA Methods 200.7 and 200.8 are common methods for determining trace metals in water and waste-water. They involve multiple acid digestion and heating steps followed by a dilution to final volume.
  • Digestion of Trace Metals in Soil Using DEENA, an Automated Sample Digestion System
    of the application note is to demonstrate that metals in soil samples can be digested by EPA Method 3050 using DEENA. EPA Method 3050 is a common method for determining trace metals in soils and solid waste. It involves multiple acid digestion steps followed by an organic removal step utilizing concentrated
  • Application Note: Atomic Absorption (.pdf)
    the wavelengths of light that are absorbed by these ground state metals to determine the concentration of metal ions in an unknown sample. Atomic Absorption Sample Preparation with the ML500 diluter: The ML500 is used to make standards, perform acid digestions, and sample dilutions for Atomic Absorption
  • Application Note: Inductively Coupled Plasma Spectroscopy (.pdf)
    with the ML500 diluter: The ML500 is used to make standards, perform acid digestions, and sample dilutions for ICP. The instrument eliminates the need for glass pipettes and volumetric glassware for large and small ratio dilutions (1:1 to 1:25,000 in a single step). The fluid path is made from Borosilicate
  • Elemental Analysis of Zeolites
    The following procedure utilizes Inorganic Ventures' UniSolv Acid Dissolution Reagents for the determination of major and minor elements in zeolites. This procedure replaces both the HF/boric acid digestion and the lithium borate fusion procedures. Accurate and precise data are obtained using
  • Medical Device Link .
    membrane used for nucleic acid immobilization was nitrocellulose, selected by E. M. Southern for his Southern blotting method.2 This technique involves transferring DNA fragments, produced by restriction endonuclease digestion of DNA, from an electrophoresis gel to a nitrocellulose membrane. A great
