1. A method for transferring a calibration algorithm from a First Apparatus to a Second Apparatus comprising:

  • (i) conducting a Primary Calibration of the First Apparatus to obtain at least one Primary Calibration Algorithm using a standard set of wavelengths;

    (ii) obtaining measurements of absorbance of a set of calibrators on the First Apparatus for at least one wavelength from the standard set of wavelengths;

    (iii) obtaining absorbance measurements of the set of calibrators on a Second Apparatus for at least one wavelength from the standard set of wavelengths;

    (iv) establishing a linear regression equation for at least one wavelength from the standard set of wavelengths using the absorbance measurements from the First Apparatus and the Second Apparatus; and

    (v) incorporating the at least one Primary Calibration Algorithm on the Second Apparatus.
