Ghost-Isotherms - Problems with Cleaning Langmuir Troughs
Fluff-free precision paper wipes are widely used for cleaning Langmuir troughs with organic solvents. The results presented in this article show that paper tissues often contain surface-active agents, which may lead to the measurement of incorrect surface pressure-area isotherms.
