Analytical Eco-scale score

Excellent green analysis

  1. Bold values represent the main factors (reagent and instrument) that affect greenness assesment of methods and to their scores which represented by pps
  2. Analytical eco−scale score = 100 (the ideal score of green analytical method)
  3. Analytical eco−scale score> 75 (excellent green analysis)
  4. Analytical eco−scale score 50–75 (the green analysis is acceptable)
  5. Analytical eco−scale score< 50 (the green analysis is inadequate)
