Chromatography News and Research

RSS

Chromatography in Greek means to ‘write with colors.’ It is a versatile separation technique developed in 1903 by Mikhail Tswett, a Russian botanist. He separated colorful plant pigments using a column of calcium carbonate. Ever since its discovery, chromatography has evolved as a powerful tool in the lab for the separation and identification of different compounds in a mixture.

New findings on vitamin D

Surprising findings by Queen's University researchers have shed new light on how the 'sunshine vitamin' - D - increasingly used to treat and prevent cancer and other diseases is broken down by our bodies.

Deodorants - a risk factor for breast cancer?

Underarm deodorants or antiperspirants are an essential part of the modern day hygiene routine, but most underarm hygiene products contain chemicals that work to disguise odour and reduce wetness. They also contain preservatives which ensure the product continues to work for a long period.
