How do you analyse azorubine in HPLC?

The azorubine was analysed using reversed phase, ion pair gradient elution HPLC with diode array detection. A summary of the procedure for this method is given in the Appendix for this chapter and the performance characteristics are given in Table 2.3.

What is the basic principle of HPLC?

Principle of HPLC. The separation principle of HPLC is based on the distribution of the analyte (sample) between a mobile phase (eluent) and a stationary phase (packing material of the column).

What is the chemical name of Azorubine?

The full chemical name of Azorubine is disodium 4-hydroxy-3- (4-sulfonato-1-naphthylazo) naphthalene-1-sulfonate, and its structural formula is shown in Figure 2.1c. Similarly to other food colours, Azorubine may also be converted to aluminium lakes, which again may contribute to the total exposure to aluminium.

What is the role of the column in HPLC?

The column represents the heart of any HPLC system. It is responsible for the adequate separation of the sample ingredients. The separation efficiency correlates with the column inner diameter, the length of the column and the type and particle size of the column packing material.
