: The violet innovation grade index (VIGI) is a pioneering metric designed to
evaluate the degree of innovation in analytical methods. This study introduces the VIGI tool
(https://bit.ly/VIGItool) and demonstrates its application in assessing the innovative potential of
various analytical techniques. VIGI integrates ten distinct criteria-sample preparation and
instrumentation, data processing and software, white analytical chemistry and its derivatives,
regulatory compliance, materials and reagents, miniaturization, automation, interdisciplinarity,
sensitivity, and approach-providing a comprehensive evaluation that complements existing green,
blue, and red metrics. Each method is assessed using a survey-based approach, resulting in a starshaped decagon pictogram that visually represents its innovation score. The VIGI metric was
successfully applied to five case studies, revealing insights into the strengths and weaknesses of
each method in terms of innovation. Methods incorporating advanced materials, miniaturized
devices, and automation scored highly, reflecting their cutting-edge contributions to analytical
chemistry. Conversely, methods lacking advanced data processing or interdisciplinary applications
scored lower, highlighting areas for potential improvement. This work underscores the importance of prioritizing innovative metrics
like VIGI in the development and evaluation of analytical methods to ensure that analytical chemistry remains at the forefront of
scientific advancement through more effective and sustainable practices.
