GC Spectrum HS-600

Granular Potassium Permanganate Impregnated Media

Spectrum HS-600 is a silicate compound impregnated with potassium permanganate. It is ideal for certain applications where activated carbon is ineffective like the adsorption and oxidation of polar or lower molecular weight compounds. Spectrum HS-600 contains a higher percentage of potassium permanganate compared to similar products thus giving it longer service life. It is also considerably less dusty than other products making for easier and cleaner handling and use.
