Scientists from Sweden, Egypt, Denmark and India have collaborated to develop a computational tool to assess the greenness of high performance liquid chromatography (HPLC) methods.
 |
This environmental assessment tool (EAT) takes into account the safety, environmental and health issues for all solvents involved or used in the chromatographic method. A total score is then calculated that can be used to compare the greenness of various HPLC methods. Although other tools have been developed to try and evaluate the green aspect of these methods, they often do not provide a sufficiently quantitative result for comparison between various methods and are not always user-friendly or widely accessible. |
The HPLC-EAT software can be downloaded free of charge at http://www.biotek.lu.se/hplc-eat/ and can also be combined with another free software eco-solvent tool to perform life cycle assessments of waste disposal options (such as distillation or incineration).
