Here, PerkinElmer reps describe a UHPLC/SQ MS method to separate, identify, and quantify some essential water soluble vitamins without the use of ion pair reagents.

Microvolume assessment of bacterial culture growth was found to facilitate measurement of undiluted cultures. Comparison between microvolume and cuvette-based data requires the use of a conversion factor, which can be simply determined.

Michael Glavanovich receives calls with all kinds of strange requests. Once, a woman phoned to ask him if a piece of meat tossed into her yard for her dog contained poison.

Various types of synthetic colorants are used as food additives, and gradient elution is generally used to analyze them. The Nexera UHPLC (Shimadzu) enables stable, ultrafast gradient elution through accurate solution delivery and the use of a high--efficiency gradient mixer.

High performance liquid chromatography (HPLC) is a powerful analytical technique used to separate, identify and quantify compounds with a wide range of differing properties.

Microvolume assessment of bacterial culture growth was found to facilitate measurement of undiluted cultures. Comparison between microvolume and cuvette-based data requires the use of a conversion factor, which can be simply determined.

Microwave Assisted Extraction offers significant benefits over traditional extraction techniques for PCB determination from environmental samples including higher sample throughput, time savings, reduced solvent, and great reproducibility.

The cleaning of cosmetic creams and lotions from glassware is achieved through a combination of detergents, hot water – programmed in automated washing system.

CEM has developed a method for the simultaneous and rapid preparation of vastly different food sample types for trace metal analysis.

Embattled like much of the United States economy, and having endured several years of anemic demand from consumers caught in the throes of a prolonged recession and high levels of unemployment, the $58.3 billion a year cosmetics and personal care industry in the US is eager for a rebound.

The simplest lab vacuum applications require little or no control; vacuum filtration and aspiration require only the simple application of modest suction.
