Finally, this HPLC method was effectively transferred to a short Ultra High Pressure Liquid Chromatographic (UHPLC) method using an Agilent 1290 Infi nity LC System for faster analysis without compromising resolution. With the Agilent 1290 Infi nity Diode Array Detector (DAD), various wavelengths were selected to quantify different colorants at their absorbance maxima.
