Recent studies suggest parabens may be carcinogenic and can cause estrogenic disrupting activity, thereby disputing the notion of low toxicity for these compounds. We present an LC/MS assay to identify several of the parabens found in hand lotion.

An expired ophthalmic solution of trimethoprim and polymyxin B sulphates was analyzed for degradants using UHPLC/SQ MS.

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.

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.

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.

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

The value of the laboratory cell culture incubator used in highly regulated research and clinical protocols is directly related to the proportion of incubator uptime vs. downtime.
