The Adsorbent Tube Injector System (ATIS) was developed at Supelco® by R&D Scientists, as a tool to assist in our comprehensive adsorbent research for thermal desorption tubes. The ATIS provides an efficient means of transferring calibration standards in either the gas or liquid phase onto the adsorbent packed tubes.
The ATIS employs the technique of flash vaporization to vaporize the sample in a continuous flow of inert gas; the inert gas carries the sample to the tube. The sample pathway of the ATIS is constructed of glass and stainless steel. The calibration standard is injected by a syringe through a replaceable septum in the center of the injection glassware, which is heated. After enough time has elapsed, typically less than five minutes, the tube is removed from the ATIS
and analyzed using the appropriate analytical technique for that adsorbent tube.
With a Vulcan® Systems Thermal Desorption Unit, hydrocarbons are separated from the solids in the sludge. The treated solids have little to no residual hydrocarbons, resulting in an end product that can be disposed of easily and cost-effectively.

What makes our equipment unique? The ability to recover diesel or oil in a way which maximizes the resaleability of use as a fuel.
Hiden gas analysis systems provide for high sensitivity, wide dynamic range, real-time analysis of almost any gas and vapour.
Hiden’s application specific gas analysis systems are tailored to meet the specific application requirements, and include a range of special sampling, vacuum pumping and vacuum accessories.
Hot zone sampling accessories are included for evolved gas analysis from furnaces, and thermo gravimetric analysers, TGA, for example.
Thermal analysis methods are vital for catalysis characterization. For thermal analysis including temperature programmed desorption TPD , temperature programmed oxidation TPO, and temperature programmed reduction TPR, studies, Hiden gas analysis systems include enhanced pumping for hydrogen and special close coupled sampling to the TPD/TPO/TPR reactor for optimum thermal analysis response...
With over 40 million tons of recycled waste in the U.S. each year, operators are fervently searching for innovative methods to treat and dispose of RCRA wastes.
Vulcan® Systems' thermal desorption technology is a proven method for recycling RCRA wastes in a manner that is efficient, affordable, and compliant with the Resource Conveservation and Recovery Act of 1976. The technology devolatizes hydrocarbons and captures them in a condensor for potential use in fuel blending, while also allowing the delisted end product to be disposed of in a more safe and secure manner.
According to the EPA's website, "[the] EPA tried to develop hazardous waste regulations that balance the conservation of resources, while ensuring the protection of human health and the environment." Vulcan® Systems' technology meets the EPA's regulations to ensure that hydrocarbons can be re-used and, RCRA Waste, now delisted, can be appropriately disposed of without damage to the environment or public health.
A by-product from burning pulverized coal in electric power generating plants, fly ash can contain substantial levels of mercury which can negatively impact human health and the environment. Responding to the threat of mercury exposure, the EPA has established tough standards for the power industry to meet.
Vulcan® Systems Thermal Desorption Units remove mercury from fly ash, making the end product reusable for concrete production. Through this process, power plants are able to create a new revenue stream through the sale of clean fly ash, eliminate expensive disposal costs, and protect the environment.
Besides solving the disposal problem, adding fly ash to concrete improves the quality of the concrete. As a replacement for Portand Cement, the use of fly ash saves on material expenses, decreases permeability, and prevents expansion, thermal cracking, and efflorescence. It also increases working time, and makes pumping and finishing much easier.
