By downloading, viewing and utilizing information from the AMGS calculator, visitors assume full responsibility for their own actions and any damages or liabilities that may result from the utilization of information obtained from the AMGS calculator.From the code from the two-sample t-tests in JASP, I see the following: num <- (ns - 1) * sds^2 + (ns - 1) * sds^2 The use and applications of programmable calculator in dietary analysis are. The Roundtable has used reasonable efforts in collecting, preparing and providing quality information and material, but does not warrant or guarantee the accuracy, completeness, adequacy or currency of the information contained in the AMGS calculator. The American Chemical Society Green Chemistry Institute’s Pharmaceutical Roundtable (“the Roundtable”) has created this AMGS calculator to inform and guide users towards greener methods. Use the following web link to read this paper. Others that tested the calculator with HPLC, UPLC, SFC or Preparative HPLC- or Preparative SFC- methods are listed as co-authors in the following Green Chemistry publication: The members that contributed to the development and launch of the calculator are: Michael Hicks (Merck, Rahway, NJ), Bill Farrell and Christine Aurigemma (Pfizer, San Diego, CA), Paul Ferguson (AstraZeneca, Macclesfield, UK), and Dave Constable, Isamir Martinez and Christiana Briddell (ACS GCI, Washington, DC).
This calculator was developed from a Microsoft Excel-based program first developed by Laurent Lehman at Bristol-Myers Squibb, New Brunswick and further improved through development by members of the American Chemical Society (ACS) Green Chemistry Institute (GCI) Pharmaceutical Roundtable’s Analytical Chemistry team.

Please e-mail for specific details on how to improve the AMGS, so we can address your comments in future iterations of the tool. It is not currently designed for gas chromatographic methods, although the team welcomes specific suggestions for future versions. This calculator is for determining liquid chromatography and SFC greenness scores only. Where both a resolution and a sensitivity solution are used, the total volume should be included for both solutions in the sensitivity solution entry.

If this solution is prepared through serial dilution, please provide the total volume of dilutions used to make the final solution. The system suitability test (SST) is typically 0.05% (v/v) relative to the API reference standard. Yellow and red colors were used to highlight areas where the method could be improved for example, in the table above, the instrument energy could be reduced by shortening the method run time. These colors are meant as an indicator highlighting the highest contribution to the AMGS value. The color coding is meant as a guideline that indicates if a specific energy score (of the three noted categories), tips the balance of the AMGS total % beyond a ~1/3 contribution. The team feels that having this metric available will provide an environmental impact awareness and encourage analysts to develop greener methods. The AMGS metric factors solvent health, safety, environmental impact and cumulative energy demand, instrument energy usage and method solvent waste to benchmark and compare one method to another. The lower the AMGS, the greener the method.
It is not meant as an absolute measure of method greenness or as a means to reject a given method based on the finite score. This tool is intended as general metric guideline to compare methods during development.
