ResinTech MBD-NANO is a 2:3 volumetric mixture of CG8-H-BL (a dark-colored hydrogen form cation resin) and SBG1P-OH (a hydroxide form type 1 porous strong base anion resin). The NANO grade means it has been functionally tested to produce > 18 megohm resistivity and under 2 ppb of TOC. MBD-NANO is intended for use in E-1.1 water applications requiring TOC of no more than 2 ppb and metals certification.
