SWIEET—a salt-free alternative to QuEChERS
Analytical and Bioanalytical ChemistryAbstractThe efficient extraction of various analytes from a wide spectrum of matrices with organic solvents is still a great challenge in analytical chemistry. Especially polar and charged compounds are hard to extract in combination with neutral analytes of intermediate to low polarity. The QuEChERS method is often chosen and has been adapted not only
