Imagine that a small child or a loved one is rushed to a hospital's emergency room, comatose or delirious because they have just consumed an unknown white powder. The doctor takes immediate action, pumping the child's stomach and using activated...

One of the most common activities of chemists is to determine the identity of elements and compounds present in a sample of material. If a chemist wishes to analyze a sample to find what elements or compounds are present, that is, to identify the...

Various techniques have been devised to permit the analysis of the structure and function of microorganisms. Some techniques are qualitative in their intent. That is, they provide a "yes or no" answer. Other techniques are quantitative in their intent....

Analytical chemistry is the study of the chemical composition of natural and artificial materials. Unlike other major sub disciplines of chemistry such as inorganic chemistry and organic chemistry, analytical chemistry is not restricted to any...

Supercritical fluid chromatography (SFC) is used in a wide variety of fields within analytical chemistry. This is because of its ability to separate non-volatile and thermally labile compounds and its compatibility with a wide range of liquid and gas chromatographic detectors. Recent literature...

A study that spurred concern about high concentrations of platinum in women with silicone breast implants seems to contain flaws and should be viewed "with caution," the scientific journal that published the work warned Monday. Questions about platinum, a heavy...

The effects are all too familiar: a fancy dinner, some fine wine and then, a few hours later, a racing heart and a pounding headache. But a device developed by University of California, Berkeley, researchers could help avoid the dreaded "red wine headache."Chemists working with...
