Since its formation, the Institut Kirchhoff Berlin GmbH has offered analyses of pesticides in foodstuffs, animal feed, water and pharmaceutical products. Over the course of many years’ optimisation and validation work, our team has acquired the expertise with which to help you overcome the ever-increasing quality demands made of your raw materials, goods and products. Every year, we analyse more than 8,000 samples for pesticides – particularly in fruit, vegetables, grains, edible nuts, cocoa and cocoa products, as well as in milk and milk products. As well as the comprehensive analyses, we also offer a legal assessment of the samples being examined. This is attested by our accreditation as an inspection agency in accordance with DIN EN ISO/IEC 17020 by the German Accreditation Agency (DakkS). In doing so, we take into account the national and international regulations, as well as client-specific requirements (secondary standards for the various arms of the food retail trade) and the organic sector. Establishing and assessing the capacity of the acute reference dose (ARfD) is also included as standard.
In order to have our performance independently assessed, we take part in regular (on average 10x a year) national and international suitability test systems (QS, FAPAS, BIPEA, PROOF-ACS, LVU). Our continuous high quality is reflected in the repeated successful participation in the QS laboratory competence test. Since 2013, we have been awarded the maximum number of points (10).
Since 2006, we have been a QS-certified lab, and since 2009 a recognised Fresh.Point contract lab (formerly 4fresh). Since 2016, we also achieved the recognition of the German Federal Agency for Natural Food and Natural Products BNN, for which our evaluation expertise was examined.
Work on panels, committees and similar bodies
We are a founding member of the German Joint Labs for Fruit and Vegetables (DeLOG) of the German Fruit Trade Association (DFHV), which met for the first time in 2011. Here we were and are chiefly concerned with the development of a basic list that describes the minimum requirements for the substances being examined. We are an active member in the LChG of the GDCH’s pesticides working group, as well as in that of the BVL section 64 of the LFGB, where since 2015 we have been involved in the revision of the QuEChERS standard.
In the framework of so-called multimethods, we can carry out screening of more than 500 active ingredients in pesticides and their metabolites, using GC-MS/MS and LC-MS/MS (combi method).For some time now, we have also taken the approach of developing matrix-based lists of substances. The current list of active ingredients is available on request from us. For fruit, vegetables and grains, screening is via the modular QuEChERS quick method (ASU L 00.00-115), and for rich matrices, using the modular multimethod ASU L 00.00-34 (expanded new edition DFG S19).
For substances and their metabolites that cannot be recorded using the multimethods detailed above, the following single methods are available:
- Total inorganic bromide
- Perchlorate and chlorate
- Chlormequat and mepiquat
- Ethylen oxide
- Glyphosate, AMPA and glufosinate
- Maleic acid hydrazide
- Hydrogen phosphide
- Phosphonic acid and fosetyl
