Testing Ames test – salmonella bacteria is exposed to a chemical under question (a food additive, for example), and changes in the way the bacteria grows are measured.. This test is useful for screening chemicals to see if they mutate the structure of DNA and by extension identifying their potential to cause cancer in hu
A clinical chemistry analyzer; hand shows size. Clinical chemistry (also known as chemical pathology, clinical biochemistry or medical biochemistry) is a division in medical laboratory sciences focusing on qualitative tests of important compounds, referred to as analytes or markers, in bodily fluids and tissues using analytical techniques and specialized instruments.

A basic metabolic panel including calcium is sometimes colloquially referred to as a "CHEM-8". Calcium, as an alkaline earth metal , is also an electrolyte, but abnormalities are more commonly associated with malnutrition, osteoporosis , or malignancy , especially of the thyroid .
Wet chemistry – is a form of analytical chemistry that uses classical methods such as observation to analyze materials usually in liquid phase. Agrochemistry – study and application of both chemistry and biochemistry for agricultural production, the processing of raw products into foods and beverages, and environmental monitoring and ...
Periodic Videos (also known as The Periodic Table of Videos) is a video project and YouTube channel on chemistry.It consists of a series of videos about chemical elements and the periodic table, with additional videos on other topics in chemistry and related fields.
General chemistry (sometimes referred to as "gen chem") is offered by colleges and universities as an introductory level chemistry course usually taken by students during their first year. [1] The course is usually run with a concurrent lab section that gives students an opportunity to experience a laboratory environment and carry out ...
Extraction in chemistry is a separation process consisting of the separation of a substance from a matrix. The distribution of a solute between two phases is an equilibrium condition described by partition theory. This is based on exactly how the analyte moves from the initial solvent into the extracting solvent.
A large fraction of the chemical elements that occur naturally on the Earth's surface are essential to the structure and metabolism of living things. Four of these elements (hydrogen, carbon, nitrogen, and oxygen) are essential to every living thing and collectively make up 99% of the mass of protoplasm. [1]
