Wonderful tutorial, but I have a couple of doubts: Does it mean, I need to perform an initial calibration for each element just the first time before make a test with the Vanta analyzer or just in case Im getting poor match percents in my results? Please let me know. Thanks
The purpose of user factors is to serve as “fine tuning” of our existing factory calibration to specific samples and testing requirements that a user might have. Once a user factor model has been established for you application, ideally no further adjustments should be necessary provided no major changes to your application and/or samples going forward. If the application changes and/or the types of samples you are working with change dramatically, it me be necessary to update your existing model, or better yet, create a new model for those types of samples. Assuming your model is setup appropriately, it is not uncommon for users to simply verify results for a given user factor model on trusted CRM(s) for you model and application (i.e. “trust, but verify”). How often you perform this check is up to the user, but once at the start of each testing day is most common. Additional verification may be necessary depending on your application (particularly if you are doing regulatory-based testing). Note: the instrument doesn’t require this check - its simply a good and common practice. User factors are simply one tool in making sure you get the best possible results from your Vanta. Its up to every user to look at their testing goals and practices to make sure that appropriate steps are being taken to ensure the best possible results. Every user will have different goals for their application, so if they have specific questions about how to approach particular applications, they should feel free to contact us at ani.applications_support@olympus.com.
