Ringversuchsteilnahmen

Die Sofia GmbH nimmt als akkreditiertes Labor regelmäßig an Ringversuchen teil. Bisher wurden die Ergebnisse auf Anfrage an unsere Kunden weitergegeben. Die letzten der von der international anerkannten Organisation zur Durchführung von Ringversuchen, FAPAS, organisierten Tests zeigen aus unserer Sicht beunruhigende Trends.

  • Die Zahl der Laboratorien, die Pestizidrückstandsanalysen anbieten wächst deutlich.
  • Der Anteil der Laboratorien, die die Pestizidrückstandsanalytik beherrschen, nimmt deutlich ab.
