Fig. 1 13X zeolite structure: Zeolites are crystalline, aluminosilicate, mineral structures with unique molecular sized pores and cavities. The primary structure of a zeolite is a tetrahedral framework of silicon (Si), aluminum (Al), and oxygen (O) atoms balanced by a cation.

Fig. 2 13X Zeolite SEM images (500 to 10,000× magnification): The number of oxygen atoms contained within the framework of the zeolite structure determines the pore size of the zeolite (observed at higher magnifications). The unique pore sizes allow zeolites to host guest molecules adsorbed during heated passive headspace extraction.
