White Analytical Chemistry: An approach to reconcile the principles of Green Analytical Chemistry and functionality

TrAC - Trends in Analytical Chemistry, 2021
Abstract The concept of White Analytical Chemistry (WAC) is presented as an extension of Green Analytical Chemistry (GAC). We propose the 12 WAC principles as an alternative to the known 12 GAC principles. In addition to green aspects, WAC takes into account other key criteria affecting the quality of the method, analytical (red) and practical (blue).
