Enzymes are proteins that “work” through different mechanisms, which is why they are usually measured by their activity (the amount of work they can do), rather than the quantity or weight present. The enzymatic activity is important to determine the effectiveness when added to a product blend or when utilizing enzymes in a production process, such as brewing. The current activity assays are based on the USP-FCC enzyme assays and report in the specified units. ARL has tested raw materials and enzyme mixes, but if there are more complex matrices, our team can evaluate the suitability of the desired assays.

Microbiological analysis is one of ARL’s “bread and butter” operations. Since its genesis in 2000, ARL has built its success around testing accuracy and on-time reporting. We offer BAM, AOAC, and USP methods, including USP 2021/2022, USP 51, USP 61/62, and USP 71. We have the experience to help you select the most appropriate method for your product and determine your acceptance criteria. Our expertise will add another level to your quality control and quality assurance programs. No matter your quality objectives, ARL’s team will help you achieve success.

In July 1, 2021, ARL began to perform routine testing of E. coli, Salmonella, and Staphylococcus aureus via Polymerase Chain Reaction (PCR) technology. ARL worked closely with BioMerieux to validate this method.
