    Area of Science:

    • Analytical Chemistry
    • Instrument Calibration

    Background:

    • The Technicon AutoAnalyzer is a widely used automated analysis system.
    • Accurate colorimeter calibration is crucial for reliable analytical results.

    Purpose of the Study:

    • To develop and validate a rapid calibration method for the Technicon AutoAnalyzer colorimeter I.
    • To compare the suitability of bromphenol blue and potassium dichromate solutions for calibration.

    Main Methods:

    • Utilized bromphenol blue solutions for colorimeter calibration.
    • Evaluated instrument working range and filter stray light characteristics.
    • Compared results with potassium dichromate calibration methods.

    Main Results:

    • Bromphenol blue solutions provide a more suitable calibration across the instrument's working range.
    • Stray light characteristics favor bromphenol blue for this specific colorimeter.

    Conclusions:

    • A rapid and effective calibration method using bromphenol blue is established for the Technicon AutoAnalyzer colorimeter I.
    • This method offers advantages over traditional potassium dichromate calibration due to instrument-specific optical properties.
