The dynamic surface tensions of aqueous solutions of Tritons (X-100, X-114, X-165, X-305, and X-405) and n-hexanol were measured with a maximum bubble pressure method in the time interval from 0.1 ms to 1 s, The possibility of formation and detection of bubbles up to a frequency of 100 Hz is needed for studies in the sub-millisecond range, which has been arranged by a special design of a measuring cell for the commercial bubble pressure tensiometer MPT1, An analysis is given for the applicability of the bubble pressure method to extremely short adsorption times,
