Molecular media is essential for effective molecular filtration solutions. At First Molecule,we offers a range of proven impregnated activated carbons designed to target a broad spectrum of odours, irritants, toxic, and corrosive gases.

While a few molecules are not effectively managed by broad-spectrum activated carbon, surface-modified or "impregnated" carbons are specifically designed to adsorb particular molecules or groups of molecules. These impregnated activated carbons can be produced from various raw materials and come in different qualities, shapes, and sizes. By adjusting these parameters, First Molecule can enhance efficiency, prolong lifespan, and reduce pressure loss for different customer needs. Depending on the application, impregnated activated carbon may function through chemical adsorption, catalytic mechanisms, or sometimes both.

Impregnated Carbon for Acids
First Molecule’s impregnation system features a premium grade of activated carbon specially designed to adsorb acidic gases, such as hydrogen sulfide, sulfur dioxide, nitrogen oxides, hydrogen chloride, and hydrogen fluoride. This grade is especially effective for managing strong acids.

Impregnated Carbon for Bases
First Molecule’s impregnation system offers a premium grade of activated carbon specially designed to adsorb alkaline gases, such as ammonia and amines.

Impregnated Carbon for Ethylene Oxide
First Molecule’s impregnation system provides a high-quality grade of activated carbon specially formulated to target ethylene oxide (ETO).

Impregnated Carbon for Mercury
First Molecule’s  impregnation system features a high-quality grade of activated carbon specifically designed to adsorb mercury (Hg) vapours . This grade is ideally suited for use in shallow to moderate bed depths where extended contact time between the mercury and the impregnated activated carbon is not feasible.
