What Are the Different Types of Chromatography?

From paper chromatography to column chromatography to gas chromatography, there are different types of Chromatography.  Chromatography is a way to separate mixtures into their parts. It is performed by passing a mixture through another substance, where the...

Dorothy Crowfoot Hodgkin | Women in Science

Dorothy Crowfoot Hodgkin was a Nobel Prize-winning chemist who developed protein crystallography. She is responsible for advancing X-ray crystallography, a method for determining a crystals 3D structure. At age 10, Dorothy became interested in chemistry and...

93 Chemicals in Cigarettes | Tobacco Products

By now it is standard knowledge that chemicals in cigarettes and other tobacco containing products are dangerous. Due to their dangerous nature, the FDA requires tobacco producers to report the levels of Harmful or Potentially Harmful Constituents (HPHCs) in their...

NIOSH Analytical Methods Testing and Analysis

The United States National Institute for Occupational Safety and Health NIOSH  publishes a Manual of Analytical Methods. The methods detail sampling and analysis of contaminants in workplace air, and in the blood and urine of workers who are occupationally exposed....

Analysis of Capsaicinoids for Scoville Heating Unit (SHU)

The Scoville Heat Scale, devised by Wilbur Scoville in 1912, has long been the benchmark for measuring the pungency of chili peppers and other spicy foods. While the original method was a sensory test, modern laboratory professionals rely on more objective, precise...

X-ray Diffraction and Compound Identification | XRD

X-ray diffraction, also known as XRD, is a method of non-destructive testing to analyze fluids, powders, crystals, and more. X-ray diffraction answers the question, "What is it?" In its simplest explanation, XRD uses diffracted intensities and angles to identify...
