Liquid chromatography solutions for the food industry

Analytical methods are essential to ensure product quality, execute regulations and to comply with food standards, specifications and labelling requirements in the food industry. 

The most important components that are analysed in the food industry can be divided into three groups:

  1. Residues and contaminants
  2. Food additives
  3. Natural ingredients
High performance liquid chromatography (HPLC) is one of the most important methods that is applied in all three fields. With a wide range of column materials and detector types, HPLC systems can be custom-made for the needed application.

Purification: 
KNAUER is also one of the few companies to offer high performance preparative HPLC solutions and continuous simulated moving bed (SMB) chromatography systems for the purification of food ingredients.

Residues and contaminants in food

The perfect HPLC system for your food analysis and quality control task

This gradient HPLC system perfectly meets even sophisticated analysis demands up to the UHPLC range. It offers first class performance and quality „Made in Germany“. This system features a low pressure gradient pump (AZURA® P 6.1L), the new autosampler (AZURA® AS 6.1L), a column thermostat CT 2.1 and a diode array detector (AZURA® DAD 2.1L) with 8 channels in the range of 190–700 nm.

Available at a special promotion price.

Dedicated HPLC system for sugar analysis

Carbohydrates, alcohols, and organic acids are important in the manufacture of many foods, pharmaceuticals, and biofuels. This dedicated system is specially designed to separate and analyze these compounds. The heart of this system is the superior AZURA refractive index detector RID 2.1L with an outstanding linear range and sensitivity. More systems components are the column thermostat CT 2.1 and the isocratic AZURA pump P 6.1L for delivery of small flow rates (0.001 -10 ml/min) and pressure up to 700 bar. This price attractive system is developed to run simple and rapid methods that enable simultaneous determination of sugars, organic acids and alcohols. Therefore, an interesting application is the analysis of all major wine compounds (see our application note) for quality control.

Focus on Beverage and oil analysis

HPLC solutions with electrochemical detection for most sensitive and selective analyses of food components

Electrochemical detection (ECD) for HPLC or UHPLC is an extremely selective and sensitive detection technique that is applied in a number of analyses in the food industry. 
Example applications include carbohydrates, organic acids and vitamins.
