To increase their stability, many cosmetics contain antiseptic compounds such as parabens and 2-phenoxyethanol. However, these preservatives are not only bactericidal but can also cause allergic symptoms in humans. This article introduces a method for the analysis of 24 types of cosmetic preservatives, either specified in the cosmetics standards established by the Japanese Ministry of Health, Labour and Welfare or regulated by the European Commission, using ultra-high performance liquid chromatography...

thumbnail image: The Basics of Micro-LC

For some time “sustainable processes” has been the phrase on everyone’s lips. As far as analytical labs are concerned there are many possibilities for saving energy or rather for using resources more efficiently. Besides the real “energy guzzlers” such as extractors and safety cabinets, complex analysis apparatus has to be subjected to critical system checks, too.

Selected key technologies of the analytical science industry are discussed by Steve Down with reference to burgeoning application areas and the scope for future improvements.

Ion source pressure plays a significant role in the process of ionization and the subsequent ion transmission inside a mass spectrometer. Pressurizing the ion source to a gas pressure greater than atmospheric pressure is a relatively new approach that aims to further improve the performance of atmospheric pressure ionization sources. A brief review on the development of super-atmospheric pressure ion sources, including high-pressure electrospray, field desorption and superheated ESI, and the strategies to...
