This document describes the analysis of azo dyes using the Agilent 1290 Infinity LC System and the 60 mm Max-Light high sensitivity flow cell. The performance of the high sensitivity method is investigated by comparing the results with those obtained using a standard flow cell.
This document describes a method for analyzing toxic aromatic amines released from banned azo colorants using the Agilent 1290 Infinity LC System. The study compares the performance of a standard flow cell (10 mm optical path length) against the Agilent Max-Light high sensitivity flow cell (60 mm optical path length).
| Optical path length (High Sensitivity Cell) | 60 mm |
|---|---|
| Optical path length (Standard Cell) | 10 mm |
| Flow rate | 1.6 mL/min |
| Detection limits | 0.2-1 ng/mL |
The high sensitivity flow cell increases sensitivity by a factor of 5-6 compared to the standard cell.
The note analyzes a set of 22 potentially carcinogenic amines derived from azo dyes.
