Photomètre à flamme


Ever since the revolutionary Model 420 was introduced we have been asked to add calcium measurement.

This has been accomplished without any reduction in the existing capability of the Model 420, due in part to the very well established aspiration, sample mixing and burner configuration of the original Model 410 system. The stable flame allows very efficient dispersion and thermal dissociation of the sample compounds leading to a reproducible emission of the elements under analysis.

Features

  • Now with Calcium which can be measured with Na and K
  • Enhanced software improving accuracy and reducing errors
  • Fully interactive with New Model 860 Autosampler
  • Another Now Flame Photometer from the Experts
  • Automation

    The New Model 860 Autosampler fi ts entirely within the dimensions of the Model 805 Diluter giving the smallest footprint available. The Model 860 Autosampler is integrated with the Model 425 operating system with a bi-directional connection. Operation couldn’t be simpler. Pressing Blank and Calibrate buttons on the Model 425 sends the Model 860 probe to the blank and calibrant vessels on board the Autosampler carousel. The system, after calibration, is ready for the run to begin. Press Measure and walk away! The Model 860 automatically detects the last sample and fi nishes the run.
