AZURA® Preparative HPLC

The permitted daily exposure for the mycotoxin patulin is 0.05 µg/mL in apple juice, as stated by the Scientific Committee on Food for the European Commission. In this application note, KNAUER presents a fast protocol for the determination of patulin from apple juice using the AZURA® HPLC plus with a Eurospher II column.

In this application note, KNAUER describes a gradient method designed to provide fast determination of six steviol glycosides using reversed-phase HPLC and UV detection. An automated matrix reduction is achieved by online SPE (solid phase extraction), aiming to speed up sample preparation and promise a high sample throughput.

In this application note, KNAUER describes how an existing analytical HPLC method can be transformed to a preparative HPLC using the KNAUER Scale-Up Converter. The example used in this application is steviol glycosides, which are often used as natural sugar substitutes due to a far higher sweetening power than normal sucrose or glucose. However, this approach is also designed to be applicable for the fast scale-up of other analytes.

In this application note, KNAUER provides a method that promises fast determination of six steviol glycosides. The AZURA® HPLC plus system is designed for fast separation in under ten minutes and an optimized gradient, promising fast quality control of Stevia products.

With the continuous increase in the price of vanilla pods, artificial vanilla flavoring agents such as vanillin are in high demand. In this application note, KNAUER outlines a method using the AZURA® UHPLC system for screening the components of different vanilla products to determine authenticity.
