Usefulness of a Direct Combustion Mercury Analyzer

Posted by Jeff Forsberg on Jun 29, 2023 2:23:47 PM

Do you have a backlog of solids and/or semisolid samples you need to analyze for mercury determination? Or are you a teaching laboratory needing an instrument to complete that proposal you wrote? Or a laboratory exploring options to enhance your portfolio? Well, I encourage you to look to Teledyne Leeman Labs for viable options.

Run it, don’t pollute it — filter your mercury exhaust

Posted by Aaron Keller on Jun 15, 2023 11:43:46 AM

Mercury poisoning is a serious concern for those of us who directly work with mercury. Mercury is a heavy metal with many adverse side effects for people and the environment, even in relatively small amounts. That is why mercury analyzers are useful for testing where health concerns exist; you likely use one in your own lab if you’re reading this.

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?

Getting to Know Your QuickTrace® - The Effect of Liquid Flow: Importance of Capillary Action (Part 2 of 3)

Posted by Aaron Keller on May 2, 2023 3:58:24 PM

This is the second in a three-part series on the QuickTrace® 

Part one is linked here, “Getting to Know Your  QuickTrace®: The Effect of Liquid Flow — Pump Rate"

The importance of the moment the liquid sample is introduced to the gas liquid separator (GLS) via the capillary cannot be understated. Read More

Getting to Know Your QuickTrace®: The Effect of Liquid Flow: Pump Rate (Part 1 of 3)

Posted by Aaron Keller on Apr 26, 2023 9:53:51 AM

There are always lots of factors when it comes to running any samples: concentrations present, liquid and gas flow rates, unit detection limits, to name a few. The liquid flow is highly important in the QuickTrace® M7600 and QuickTrace® M8000 due to the sample and reagents being introduced by the liquid flow. In this three-part series, we will focus on three major elements that can affect liquid flow: the pump rate, the capillary action, and the tubing.

Mercury - From Fire to Ice

Posted by Sara Kennedy on Apr 3, 2023 3:18:47 PM

A lot of focus is put on anthropogenic (human-caused) releases of mercury into the environment, but let’s take a closer look into a powerful, natural source of mercury: volcanoes! We’ll explore why volcanic eruptions can increase global mercury levels, how we measure mercury released from past major eruptions, and how those measurements inform our policies for the future. So, how does mercury move from fire to ice?

Nobel Prize Metals

Posted by Sara Kennedy on Feb 22, 2023 12:34:09 PM

“While the invading forces marched in the streets of Copenhagen, I was busy dissolving Laue’s and also James Franck’s [Nobel Prize] medals.”1

Let us travel back to the 1940s. The Second World War is sweeping across Europe. As Denmark is being occupied by German forces, George de Hevesy doesn’t need to use weapons to protect his colleagues. He relies on science!
