Video FAQ

Questions

  • Why is no field calibration needed?
    • The benefits of TDLS measurements: Drift is negligible and does not affect analyzer performance.
  • Why online validation?
    • Ensure proper analyzer functionality
    • Must for analyzers without reference cells
    • Must for low concentration applications
  • Frequency of validation checks?
    • Depends on the application.
  • Is validation an accuracy check?
    • No, it is a functionality check. 
  • Purpose of validation checks?
    • Analyzer response
    • Peak position check
  • What are the validation steps?
    • Before process snapshot is taken
    • Validation gas introduction and after stabilization a during validation snapshot is taken
    • The non-process area is then purged and an after validation snapshot is taken.

Industries

  • Chemical

    Chemical plants rely on continuous and batch production processes, each posing different requirements for a control system. A continuous process calls for a robust and stable control system that will not fail and cause the shutdown of a production line, whereas the emphasis with a batch process is on having a control system that allows great flexibility in making adjustments to formulas, procedures, and the like. Both kinds of systems need to be managed in available quality history of product, and to be able to execute non-routine operations. With its extensive product portfolio, experienced systems engineers, and global sales and service network, Yokogawa has a solution for every plant process.
