A similar result to the one of p-BQ was obtained when the sublimation of D-(+)-camphor [D-(+)-Cph] was utilized to evaluate the impact of the gas speed on the sublimation rate (Figure ). In this case, two runs were conducted under the same milling conditions (10 Hz) but with a different gas flow. As expected, using a higher flow of 1.5 L/min resulted in a fast consumption of the analyte in the milling jar while a low flow of 0.125 L/min allowed a constant evolution of gaseous species.
