  • 16HV785: Programmable Lead Acid Battery Charger
    The 16HV785 provides an unprecedented level of configurability for charging lead battery packs. Its precise, 10-bit Analog-to-Digital converter and high-frequency Pulse-Width Modulator enable the 16HV785 to provide optimum control of charging algorithms for lead battery chemistries. Special
  • Zeta Potential Measurement (Aqueous and Non-Aqueous, Iso-Electric Point Determinations)
    measurements can be used as quality tools as well as for development and trouble shooting purposes. The data obtained can help improve processes and final product quality as well as determine areas where formulation changes can lead to cost savings and increased productivity. Capillary rheology
  • Determination of Harmful Substances in Very Small
    . (Restriction of Hazardous Substances), DIN EN 71. (Safety of Toys Standard) and CPSIA (Consumer. Product Safety Improvement Act), specify maximum. permissible values, particularly for heavy metals. For example, the RoHS limits concentrations of lead. (Pb), mercury (Hg), hexavalent chromium (Cr VI
  • Determination of Connector Operating Voltage (.pdf)
    lead to the development of generic stan-. dards providing adequate guidelines. In particular IEC60664 is recommended. This specification uses creepage distance instead of test volt-. age as calculation basis for the operating voltage taking into account the above mentioned long term. effects
  • Techniques for Online Determination of VOCs in Water (.pdf)
    Objectives include: to provide an alternative to grab sampling of VOC's in water which can lead to expensive fines if not found in a timely fashion, to provide a faster method (< 1 hour) of analysis than the laboratory (3 hours to weeks), to provide a means for process control rapid feedback
  • Test and Characterization of Laser Diodes: Determination of Principal Parameters
    to establish whether or not the laser diode meets the desired specifications. The following is a brief description of the common parameters that can be experimentally determined and the techniques involved in the analysis of the raw data that lead to meaningful and easy-to-interpret results. Perhaps
  • RoHS - Determination of Harmful Substances in Very Small Concentrations
    . (Restriction of Hazardous Substances), DIN EN 71. (Safety of Toys Standard) and CPSIA (Consumer. Product Safety Improvement Act), specify maximum. permissible values, particularly for heavy metals. For example, the RoHS limits concentrations of lead. (Pb), mercury (Hg), hexavalent chromium (Cr VI
  • Determination of Volume Percent Retained Austenite by X-Ray Diffraction (.pdf)
