New USEPA Rule Proposal Directed at Wastewater Produced at Coal Fired Utilities

Posted by Jeff Forsberg on Sep 1, 2023 8:30:42 AM

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.

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?
