What is a hg monitor?
Mercury Analyzer is a portable multifunctional atomic absorption spectrometer with Zeeman background correction, which eliminates the effect of interfering impurities. This enables the user to conduct real time air monitoring and detection of mercury vapor.
What does HG stand for on the periodic table?
mercury (Hg), also called quicksilver, chemical element, liquid metal of Group 12 (IIb, or zinc group) of the periodic table.
What is the chemical name of HG?
Mercury is a naturally occurring trace metalloid element and known neurotoxin with atomic symbol Hg, atomic number 80, and atomic weight 200.59.
How does mercury Analyzer work?
The liquid sample and reductant are pumped into a gas liquid separator where a gas is bubbled through the liquid mixture to release the mercury vapor. A typical analysis time is 1–3 min. The amount of mercury in the vapor is detected using atomic absorption or atomic fluorescence.
What is the symbol of uranium?
Why is silver called AG?
The symbol Ag derives from the Latin argentum and Sanskrit argunas from “bright”. The Latin word for silver is argentum. Silver has been known since ancient times.
Why should you never touch mercury?
Mercury is a very toxic or poisonous substance that people can be exposed to in several ways. If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed. If you touch it, a small amount may pass through your skin, but not usually enough to harm you.
Why is mercury called Quicksilver?
Mercury’s chemical symbol, Hg, comes from the Greek “hydrargyrum” meaning liquid silver. Mercury is also known as “quicksilver,” a reference to its mobility. The symbol for the planet was used by the alchemists to identify mercury before it was given its more modern chemical notation.
How does cold vapor atomic absorption spectroscopy work?
Cold Vapor Atomic Absorption Spectroscopy Their work described a device for flame AA that enabled them to reduce mercuric ions in solution to ground state atoms and transport the mercury to the optical path of the spectrometer for measurement. Thus, cold vapor atomic absorption was born.
Can you touch uranium?
Uranium is pretty safe to handle yes. Enriched uranium is dangerous, because we’ve purified/concentrated/bred a certain isotope of uranium which is signifigantly more unstable.
Is silver a main group element?
The metals in group IB (copper, silver and gold) are sometimes called the coinage metals. The columns with A (IA through VIIIA) are called the main group elements.
