- Activated AluminaActivated Alumina is an aluminum oxide that is highly porous and exhibits tremendous surface area. It is resistant to thermal shock and abrasion and will not shrink, swell, soften nor disintegrate when immersed in water.
- Activated CharcoalActivated Charcoal (or Carbon) is a versatile and high capacity adsorbent of hydrocarbons, organics and odors. It is used for the removal of hydrocarbons from liquid and gas streams and the removal of odors.
- Grade ACActivated Charcoal is commonly used throughout the health physics industry as an air sampling trap. Contaminates adsorbed on the Activated Charcoal can be quantitatively determined and them compared to NIOSH Standards. Activated Charcoal is used to adsorb trace quantities of contaminates, such as pesticide, from solvents. It is the ideal oil mist removal agent for compressed air. It is also the preferred adsorbent for the trapping of hydrocarbons in inert gas streams.

- Type 4A-Moisture IndicatingMoisture-indicating Molecular Sieves are beads that have been chemically impregnated to display a blue color when fully activated by removing the water of hydration. When a gas stream is dried using this product, the blue color will turn to pink as water is adsorbed denoting saturation of the sieve. The sieve may then be reactivated at 200°C under vacuum or nitrogen atmosphere for several hours. More conveniently, the sieve may be replaced from fresh stock.

- Humidity Indicator CardsHumidity Indicator Cards are simple “hygrometers” that rely upon the reaction of a chemical agent impregnated on each card with water in the surrounding atmosphere to show within a narrow range of accuracy the prevailing Relative Humidity. Humidity Indicator Cards can be used in conjunction with a Desiccant in order to assure that the Relative Humidity within a package, compartment, electrical panel, vessel, instrumentation cabinet or sealed container never approaches levels that would cause corrosion. condensation or equipment failure. The “Active” (Blue) condition of the card can be restored many times with the application of fresh desiccant when card spots become “Saturated” (Pink). These cards are accurate within the range of plus or minus 2.5% RH.

These cards are accurate within the range of plus or minus 2.5% RH.
- Super Siloxane Adsorbent Silica GelThe field of Bio Energy is rapidly expanding. Municipalities and private waste handlers are increasingly being called upon to utilize the Methane Gases generated at solid waste landfills and sewage treatment plants rather than directing this gas to “flare.” Many waste processing sites are turning to the use of gas turbines in order to convert this gas to clean energy. Increasingly, the manufacturers of personal care items have included Siloxanes in the chemical formulation of these products. Sludge treatment facilities and newer landfills are now producing Methane gas that carries higher levels of Siloxane as a component. This Siloxane component of the combustion gas leaves microcrystalline Silica deposits on heat exchangers and the combustion surfaces of gas turbines. As a result, the manufacturers of gas turbines and reciprocating engines are now calling for the reduction of the presence of Siloxane in combustion gases in order to warranty their products. Microturbine and catalyst failures have focused industry-wide attention on Siloxanes.
- Container-Dri II®Container Dri® II is a line of specially designed cargo desiccants aimed at protecting cargo during shipping by aggresively absorbing moisture from the air. In doing so, Container Dri® II reduces dew point temperature (the temperature at which condensation begins to form, causing “container rain”), keeping cargo safe and dry. The Container Dri® II line includes several configurations to best fit different needs and modes of transport.
