Here’s what our customers say

  • Norbert Vaje (Technischer Leiter)
    Rondo Food GmbH & Co. KG (Snackprodukte)
    Krefeld, Deutschland
    “The stability of the Microtracers was the decisive argument for us. Our extruded snack foods for dogs and cats are manufactured under extreme conditions. This method has enabled us to clearly prove the high quality of our product.”
  • Nils Lastein (Application Manager, Feed)
    Andritz Feed & Biofuel A/S (Mixer Producer)
    Esbjerg, Denmark
    "Microtracer are our choice for testing new mixers. The different Microtracer colours allow us to check the homogeneity in our mixer for different mixing times in one batch only."
  • Dr. Sönke Landgraf (Geschäftsführender Gesellschafter)
    Lexa Tierernährung (Mineralfutterhersteller)
    Kirchheim/Allgäu, Deutschland
    “No products for one species may be allowed to carry over into the next production batch for another species at any time. We have determined the level of carry-over on-site with Microtracers.”
  • Hans Van Gorp (Managing Director)
    Van Gorp Diervoeders B.V. (Organic Feed)
    Waalwijk, Netherlands
    "We are testing our production lines in both of our factories. Microtracer is used as well in regular as in organic certified feed, because they are not toxic or doing any harm to the environment."
  • Karl Schulze König (Geschäftsführer)
    SKS Schulze König Zucht- und Nutztiere GmbH & Co. KG
    Steinfurt-Borghorst, Deutschland
    “As a state-approved breeding operation, the health of our animals is of prime importance to us. For our feed, we use only the highest quality components. Microtracers have enabled us to rapidly determine the correct mixing time for our special feeds.”
  • Mr. Marnix de Schrijver (Head of Lab)
    FFQ Laboratorium
    Merksem, Belgium
    "Microtracer Analysis of homogeneity and cross-contamination is a service to our customers. Contamination sources in a production line can be detected easily."

  • "PETS International" October 2018
    Frequent analysis of homogeneity and carry-over is needed to guarantee product safety and excellence for consumers in the pet food industry.

  • Trade journal “Feed Magazine | Kraftfutter” no. 3/2009
    The Microtracer analytical method is a reliable method for determining homogeneity and cross-over in mixing equipment in accordance with Feed Hygiene Regulation (EC) no. 183/2005.

  • Trade journal “De Molenaar” no. 11/2014
    Microtracers are not classified as dangerous according to REACH Regulation (EC) no. 1907/2006 and are increasingly used as a preventive measure for the traceability of feedstuffs in order to guarantee safe products.

  • Trade journal “De Molenaar” no. 21/2006
    The “direct” Microtracer method relies on the particle count principle and not on the measurement of concentrations. As a result, influences on mixing processes such as the tapping of filters are recognised with significantly greater precision and clarity.
