  • Sample Preparation Application Note (.pdf)
    One factor that may affect the water activity (aw) measurement is the sample preparation procedure. Eliminating or reducing this potential variable will yield more consistent and reliable water activity readings. Reducing variability due to sample preparation will also enable researchers
  • Sample Preparation Guide Techniques for 70+ Periodic Elements
    This Sample Preparation guide is intended to provide specific and highly detailed information about certain elements in regards to sample preparation. In contrast, my previous guides, Trace Analysis: A Guide for Attaining Reliable Measurements and ICP Operations: A Guide for Using ICP-OES
  • Medical Device Link . A Practical Guide to ISO 10993-12: Sample Preparation and Reference Materials
    to each study, sample preparation and reference materials are covered in ISO 10993-12. The standard describes the types of test samples, suitable extraction vehicles and conditions, and appropriate reference materials to be used as controls. This article reviews the standard's requirements
  • Evaluating sample preparation techniques for cleanroom wiper testing
    to develop and recommend a measurement based on scanning electron microscopy (SEM). The use of SEM metrology for particle counting provides a method that is sufficiently sensitive to discern with great accuracy the number of particles released during sample preparation. However, the issue of how to prepare
  • Sample Preparation Guide: Considerations In the Preparation of Elemental Chemical Solutions
    My previous guides, Reliable Measurements: A Guidebook for Trace Analysts and ICP Operations Guide, have dealt with the theory and basics of the common sample preparation techniques. This Guide is intended to provide specific and highly detailed information about certain elements in regards
  • Sample Preparation of Electronic Scrap in the Context of RoHS and WEEE (.pdf)
    Since August 2004 new EU directives for the disposal of used electrical and electronic appliances as well as the restricted use of certain hazardous substances in these devices have become effective. All EU countries have to adopt these directives through national legislation, which will not only
  • Preparation of Samples for Aflatoxin Testing
    , "Finely grind and mix thoroughly each laboratory sample using a process which has been demonstrated to achieve complete homogenization". Experimentation by a number of authorities has identified that preparation of samples by slurrying offers significant advantages over dry milling. Silverson high
  • Digestion of Trace Metals in Wastewater Using DEENA, an Automated Sample Digestion System
    DEENA, an automated sample digestion system, alleviates most of the manual sample preparation and produces consistent and accurate analytical results. Manual sample preparation often consists of many steps that are both labor intensive and time consuming. There is often a clear desire
