The present study developed a method based on lab-made nano-liquid chromatography coupled to ultraviolet and MS detection to separate ten phenolic acids (PAs). The PAs were extracted from coffee powder and its spent grounds by using different green solvents and natural deep eutectic solvents (NADES). The developed nano-LC-UV method was extended to MS detection by using a liquid–junction ESI interface to confirm the presence of some PA in all coffee samples previously revealed with UV detection by means of the fortification method. Finally, following the principles of Green Analytical Chemistry, the ecologicality, practicality, and applicability of the method were evaluated by applying the AGREEprep metric.
