QuoData organizes in-house training for validation of analytical methods
In addition to the development of software and concepts for analytical quality assurance, QuoData also provides individual in-house workshops and training. Topics, training materials and examples are always adapted to the field of application of the participants.
From 23 to 24 May 2018, QuoData held a two-day in-house training course on the validation of analytical methods and DIN EN ISO/IEC 17025:2018 based on practical examples on behalf of one of the world's leading providers of solutions for the healthcare market.
Artificial neural networks for the detection of food fraud - Data Scientists at Eurachem workshop in Dublin
The Eurachem Week 2018 took place from 14 - 18 May 2018. As a developer of mathematical-statistical concepts for quality assurance QuoData contributed to the event. Its data scientists and Carsten Uhlig of Akees GmbH presented a new approach to detect food fraud more quickly at the "Workshop on Data - Quality, Analysis and Integrity”, which was developed in cooperation with the Federal Office for Consumer Protection and Food Safety (BVL).
Joint research project – app to determine the best before date
Often food is still edible after the best before date, but is still sorted out by the consumer.
On the other hand storage conditions that are not optimal can shorten the shelf life.
A joint research project funded by the German Federal Ministry of Food and Agriculture (BMEL) is to find a remedy.
