Highly Efficient Molecular Adsorbers

Abstract

Molecular adsorbers developed to reduce contamination of sensitive optoelectronic components inside housings of scientific instruments. Contaminants stick to surfaces of these devices. Needed in situations in which simply venting contaminants to environment not an option because environment even more contaminating. Useful for variety of purposes in addition to suppressing contamination. Used as collection devices for sensitive total-mass-loss measurements on specimens of materials exhibiting low outgassing or as passive witness plates for collection of contaminants to be analyzed subsequently. Temperature-differential desorption from adsorbers used for preliminary separation of chemical species prior to mass spectroscopy or as alternative to gas chromatography/mass spectroscopy.
