This new IC method that includes sample preparation and four-micron column technology allows lactose determinations in non-dairy food samples labeled as low-lactose and lactose-free. The described instrumental setup includes a rinsing step to ensure good retention time stability in these complex samples. The method was shown to confirm “lactose-free” designations of foods sold in France that must conform to a 0.01% limit.
