Teledyne Leeman Labs Blog

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.

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.

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?

We are in a battery recycling boom! A strong push from consumers for corporate responsibility in source origins and greener options overall has been felt by companies all over the world. Using recycled materials can be a cost-effective, logical choice for supporting Green Initiatives and boosting the bottom line.

This is the third in a three-part series on Getting to know your  QuickTrace^® — The effect of liquid flow.

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

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.

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?

Hey Again! Let’s talk about having some fun while saving some money — lots of money, as a matter of fact!

In the world of green this and green that, with electric vehicles, lawn equipment, and scooters, we want to do our part to make the planet a better place.

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!
