Food safety is an important factor facing manufacturers today, whether it be for human consumption or for pet food. Dog owners are often critical about the quality of the food they will purchase for their dogs, demanding food that is both nutritious and free of dangerous contaminants. Liquid chromatography-mass spectrometry (LC-MS) is ideally suited to analyzing food samples due to its ability to efficiently separate compounds and the specificity of the detection technique.

This application note examines the use of KnowItAll software in addressing real-world food safety challenges. The seamless combination of targeted and non-targeted approaches within KnowItAll's unified platform provided multiple lines of evidence confirming allopurinol contamination in the dog food sample tested.
