President Biden’s Executive Order 13990 directed the U. S. Environmental Protection Agency to undergo a policy and regulation review of changes to the Clean Air Act set forth during President Trump’s administration. The order instructed the EPA to suggest revisions and/or cancellation of regulations and policies that at first glance do not seem to be in the best interest of public health.Read More
Teledyne Leeman Labs Blog
Teledyne Leeman Labs offers multiple mercury (Hg) analyzers which can determine total mercury concentrations in samples at the ultra-trace level. The final installment of this three-part blog series will be an introduction to the QuickTrace line of mercury analyzers: the QuickTrace M-7600 and the QuickTrace M-8000.Read More
In Part 1 of this series, sample collection, container types, and preservation techniques for low-level total mercury (Hg) analysis were discussed. In Part 2, I will highlight contamination sources from chemicals and the potential for analyte loss associated with digestion protocols.Read More
Mercury (Hg) determination at the ultra-trace level is an essential part of environmental assessment and drinking water monitoring. But this type of analysis comes with distinct challenges.Read More
The gold standard. Go for the gold. A gold medal.
Gold is highly prized for its beauty, as a measure of wealth, a jewelry mainstay and more. When it comes to the analysis of mercury, gold has a very particular value in obtaining data at the ultra-trace level.Read More
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.Read More
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.Read More
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?Read More
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.Read More
