Taking into account the ionic character of the system, TS/HI has been shown accurate to such systems50,51. Later on, as better microscopes were built, the pore opening was measured again and confirmed to be closer to 9 Angstroms in diameter; however, this happened years later, so the name remained as Type 13X molecular sieve. Furthermore, Delgado and Aren observed a perturbation of the silanol band attributed to the interaction of free silanols with CO2 on H-Beta27.
