Beta blockers can be abused in sports involving little physical activity, such as archery, to reduce cardiac contraction, heart rate, and coronary blood flow.

The migration to chromatographic methods utilizing smaller particle sizes has been well demonstrated to increase productivity through faster, more efficient separations.

As analytical chemist(s), the data collected from samples we test represent information. That information may be required to direct environmental clean-up operations, help insure worker safety, or guide decisions for an emergency response to a chemical incident.

Positron emission tomography (PET) is one of the most powerful noninvasive diagnostic tools for tracing organ functioning. Quality control of the short-lived radiopharmaceuticals is challenging, not at least because of the tough time limits, the radiation issue, and the near nanomole radiotracer quantities.

Red wine is a challenging matrix that contains organic acids, sugars, phenols, and pigments such as anthocyanins. This application note describes a simple, fast, novel, and effective method to clean up red wine co-extractives.

Shale gas reservoirs, such as the Marcellus shale reserve in Pennsylvania and Barnett shale reserve in Texas are a growing source of natural gas in the United States. Hydraulic fracturing or "fracking" involves pumping water, sand, and chemicals at extremely high pressure into deep underground wells to crack open hydrocarbon-rich shale formations and extract natural gas.
