The following sentences were extracted from the published full text as evidence of the instrument's experimental use.
The charge accumulated by a neutral, deionized water drop ( V = 45 μL, Sartorius Arium Pro VF, 18.2 MΩ resistivity, in equilibrium with atmospheric CO 2 , pH ≈ 6) sliding on an initially neutral hydrophobic substrate was measured using a gold-plated metal electrode connected to a subfemtoampere current amplifier (rise time: 0.7–1.8 μs, FEMTO DLPCA-200, Berlin, Germany; details in the Supporting Information S1 ).
