Arizona Instrument’s line of Jerome® toxic gas analyzers is designed to provide accurate and reliable data in compact, rugged and easy to use packages. Our patented gold film sensor technology in particular is referenced in countless other patents dealing with mercury waste and removal, just some of which are listed below.
Jerome is a trusted standard when it comes to mercury detection, which is why inventors the world over have utilized its superior accuracy and precision to assist in the development of their own inventions. Its ability to quickly and accurately detect and measure low levels of mercury in ambient air makes it ideal for applications such as industrial hygiene monitoring, mercury spill clean-up and mercury exclusion testing. All hand-held Jerome mercury analyzers weigh less than 7 pounds, making them ultra portable, and their simple push-button operation allows users with various backgrounds measure mercury levels as low as 0.05 µg/m3.
Emission Control System – US 8580214 B2 (Nov. 12, 2013)
- Related Patents: US 20140158029 A1 (Jun 12, 2014), CA 2839338 A1 (Aug 9, 2012), CN 103429319 A (Dec 4, 2013), EP 2670515 A1 (Dec 11, 2013), US 20120195815 A1 (Aug 2, 2012), WO 2012106455 A1 (Aug 9, 2012)
Shaw Environmental & Infrastructure, Inc. used a Jerome analyzer to evaluate the effectiveness of a system they were developing. The system used hydrogen bromide (HBr) to oxidize elemental mercury by heating a sample of air with a known concentration of mercury vapor until it maintained a consistent temperature and then introducing HBr vapor to help kick-start the oxidation process. After the mixture of gases was sent through a tube furnace, it was bubbled through an impinger of potassium chloride (KCl) to remove the oxidized mercury.
The Jerome was used to measure the mercury concentrations of the samples both before and after each trial was conducted to verify the effectiveness of their emission control system.
Method and Apparatus for NOx and Hg Removal – US 20080044333 A1 (Feb 21, 2008)
- Related Patents: US 7416582 B2 (Aug 26, 2008), WO 2006010262 A1 (Feb 2, 2006), US 20060021506 A1 (Feb 2, 2006)
Leo Hakka and his team designed a cyclic process for removing NOx and Hg from a gas stream. To remove the mercury, the team added a solution of a ferric salt and potassium permanganate (KMnO4) to the inlet gas, which oxidized the elemental mercury so that it could be absorbed by a liquid medium and then safely disposed of.
To test the device, the team used a mercury generator to create a gas stream with a known concentration of mercury. A Jerome mercury vapor analyzer was used to confirm that the mercury generator was working correctly. The Jerome was used again at the outlet of the system to measure the amount of mercury vapor present in the treated gas.
Recycling Container for the Collection and Temporary Storage of Mercury Contaminated Wastes in Dental Facilities – US 7673746 B2 (Mar 9, 2010)
- Related Patents: US 20080257759 A1 (Oct 23, 2008)
Mark Stone and his team invented a recycling container for mercury contaminated dental waste. The container itself is hollow and has an air-tight, self-closing lid/door that automatically closes after each waste disposal. The filter bag that covers the inside surface of the container has holes in it that allow air to be exchanged. Because of the controlled air flow, mercury vapors are released from the dental waste and then bind to the filter bag – safely stored and ready for disposal.
A Jerome was used to determine the mercury vapor level of a given dental waste sample before the sample was placed into the container. After a set amount of time, the sample was removed and another Jerome was used to measure the mercury vapor levels left within the sample to determine how much of the Hg was bound to the filter bag within the container.
