On this work, Blue Applicability Grade Index (BAGI) is proposed as a brand new metric instrument for evaluating the practicality of an analytical technique. BAGI will be thought-about complementary to the well-established inexperienced metrics, and it’s primarily centered on the sensible features of White Analytical Chemistry. This instrument evaluates ten predominant attributes together with the kind of evaluation, the variety of analytes which are concurrently decided, the variety of samples that may be analyzed per hour, the kind of reagents and supplies used within the analytical technique, the required instrumentation, the variety of samples that may be concurrently handled, the health for goal of the analytical technique, the automation diploma, the kind of pattern preparation, and the quantity of pattern. By way of the analysis of those attributes, an asteroid pictogram is generated, along with the respective rating. To facilitate using the metric a easy, open-source software was created (mostwiedzy.pl/bagi). It’s accompanied by an online software out there at bagi-index.anvil.app. The performance of the instrument was demonstrated by evaluating the applicability of 5 completely different analytical strategies as case research. All issues thought-about, BAGI will be simply used to establish the weak and powerful factors of a technique by way of applicability and to match the efficiency of various analytical strategies. We imagine that BAGI metric instrument will achieve not solely consideration but additionally belief and acceptance from the chemical group.
