Question
Can Hach COD vials be used with another manufacturer's instrument?
Summary
Utilizing Hach COD reagents with other manufacturer's instruments
Answer
The Hach COD vials can be used with any spectrophotometer that can fit the round 16-mm test tubes, or that has a 16-mm round cell adapter. A calibration curve must be made at the appropriate wavelength using COD standard solutions; different COD ranges are read using different wavelengths so check the Hach method for this information.  Check the instrument manual for instructions for entering and storing a calibration curve.
