High Throughput Analysis of Food and Oil Contaminants

Fully automated analysis of MCPD, 2-MCPD, 3-MCPD and Glycidyl fatty esters.

Analysis of Contaminants designed for your Challenges

Process contaminants of the food industry were evaluated by the EFSA (European Food Safety Authority). Zinsser Analytic invented a new system for contaminant analysis in food and oil samples in collaboration with a food quality and safety lab, addressing your everyday workflow challenges with the following substances:

With our system you will have a lot of advantages combined:

Reproducible and reliable results
Certified workflow
A larger throughput
Less health impaired staff from manual pipetting
Simplified sample handling

Stacker for lids.

CERTIFIED AUTOMATABLE PROCESSES

The presented automated high throughput sample liquid handling system performs four different well established methods to analyze 3-MCPD and 2-MCPD (free and ester form), as well as glycidyl ester in oil and fat containing samples.

With the standard pipetting tips almost every liquid can be handled. The gripper for racks and vials can handle every needed vial and rack type, as well as rack lids. Sonication of vials could be performed with the incorporated ultrasonic bath. The needed centrifugation steps are performed with the centrifuge underneath the workbench with a corresponding cut-out for the gripper to install the racks with the centrifuge.

The methods applied can be changed, depending on the certified process desired: Alkaline transesterification of glycidol to 3-MCPD (DGF method, Cd 29c-13), alkaline transesterification of glycidol to 3-MBPD (SGS 3-in-1 method, Cd 29b-13), acidic transesterification (Unilever combined method, Cd 29a-13) and single compound analysis.
