Dairy Chemistry (QDCS)
"Our dairy chemistry proficiency testing scheme - covering a wide range of analytes from aflatoxins to antibiotics…"
Analytical testing is vital in assuring that dairy products such as milk, whey, cream, and cheese are free from contaminants and adulterants before they reach customers. The AXIO Proficiency Testing Quality in Dairy Chemistry Scheme is suitable for laboratories using both traditional and modern instrumental techniques for dairy analysis, and provides samples to cover a wide spectrum of established and emerging matrices – including yogurts, freeze-dried, skimmed and powdered goods, plus hard and soft cheeses. The range of analytes included is also extensive: from aflatoxins to vitamins, energy content to natamycin, and antibiotics to Staphylococcal Enterotoxins. Successful participation in the QDCS dairy chemistry proficiency testing scheme is an essential part of developing a quality system to ensure that your laboratory’s results are both accurate and meaningful.
