  • Determination of Additives and Preservatives in Beverages by Isocratic HPLC

    The Earth is 75% water, as are most life forms on Earth. People need to drink several quarts of water a day to live well, and most of us prefer to consume beverages other than water to satisfy our thirst. Soda (or Pop depending on your location) is the primary drink of the average American; and all Soda is manufactured (as opposed to coming out of the ground from a spring in Maine). As such, ...

  • Analysis of Organic plating Bath Additives and Chemicals by Isocratic HPLC

    In today’s world, over 75% of all metal surfaces on manufactured metal “items” have some sort of plated finish on them. From highchromium steel car bumpers to zinc diecast toys to Silver-contact electronic components. While the primary composition of these plating baths are inorganic (the metals and salts that are used to make up the desired metal finish), almost all types of plating baths; from ...

  • The development of cation-exchange chromatography in free amino acids analysis

    Although it was not called a liquid chromatograph, the first such instrument was introduced in late 1959 by Beckman Instruments and was designated the M.S. Amino Acid Analyzer in honour of Moore and Stein. Inject valves had yet to be invented, the buffer switching valves were glass stopcocks and the column temperature was controlled by circulating water baths. Two positive displacement pumps ...

  • Out with the old, in with the new…

    We’re all familiar with the adage, “Out with the old, in with the new,” but we probably tend to think of it as it applies to clothes for donation or past relationships, and maybe not in terms of updating our old laboratory equipment. After attending my first WCBP conference, held in Washington, D.C. during January, and hearing life cycle management and ICH Q12 being discussed ...
