Mercury Stability in Hydrochloric Acid vs. Nitric Acid

Posted by Sara Kennedy on Jan 5, 2024 1:51:10 PM

Teledyne Leeman Labs has been in the mercury (Hg) analysis business for more than 30 years. We have had a variety of product lines reach new markets and address tighter regulations. In that time, one thing has remained constant across all our instruments: the need for accurate mercury standards to form the building blocks of the calibration curve. Analytical results are only as reliable as the calibration curve to which they are compared, and creating stable mercury standards comes with unique challenges.

Do you know your QuickTrace M-8000's PMT voltage?

Posted by Sara Kennedy on Jun 5, 2023 10:03:20 AM

We often get asked if there is an ideal photo multiplier tube (PMT) voltage for the QuickTrace® M-8000. The truth is the optimal value is unique to each instrument’s detector. It varies from instrument to instrument. During the initialization process, after connecting to the QuickTrace software, the M-8000 will select the voltage that is right for the PMT inside that system. This is the same process as clicking the Auto Select Voltage button in the Instrument Control menu. So, why is there another Set Volts option in that same menu?

First Day as a Quality Control Chemist

Posted by Aaron Keller on May 10, 2022 10:01:45 AM

Hey All, I am one of the newest members of the Teledyne Leeman Labs team and getting my start as a Quality Control Chemist for the Mercury Analyzers. I really came across the position shortly after college, in part from my research as a senior, identifying heavy metals in wastewater, specifically Mercury and Selenium. My professor reached out thinking the position would be perfect for me since I had expressed a large interest in working on the instrumental side of chemistry, and it being similar to my research. I was overwhelmed at first having little knowledge of the company before hand and the analyzers being different in the technology compared to what I had previously run. The methods were very similar, for most of the analyzers in practice but getting to know and work with 4 new analyzers was still a lot to take in. Ultimately, I was excited for the challenge, even with the overwhelming amount to learn as I was becoming bored with the monotony of my current job at the time, and felt I was mostly isolated in the lab.

Tungsten Carbide Production and Quantification of Purity using a DC Arc Spectrometer

Posted by Jason Davis on Aug 4, 2014 12:55:31 PM

Tungsten Carbide (also called cemented carbide or simply carbide) is a metal composite created from tungsten carbide and a binder metal (usually cobalt or nickel) in powder form that is compacted and sintered in a furnace. Tungsten Carbide is used for tools, abrasives, jewelry, industrial drills, and armor-piercing ammunition due to its exceptional hardness (8.5-9.0, surpassed only by diamonds). Because the tungsten carbide particles are captured in a binder during the sintering process, the result is referred to as “cemented”.

Copper Ore to High-Purity Copper, and the Quantification of Purity

Posted by Jason Davis on Jul 22, 2014 8:54:14 AM

Modern copper ores contain less than 0.6% copper, and less than 2% total volume of economic ore minerals (including copper). A majority of the ore is comprised of unwanted rock and gangue minerals (typically silicate minerals or oxide minerals). Separation of ore minerals from gangue minerals entails complicated and labor intensive processes.
