Vitamin D status has been associated with a variety of disease states including cancer, cardiovascular disease, diabetes, multiple sclerosis, osteoporosis, rheumatoid arthritis, and chronic pain.

LC/MS provides an excellent alternative to conventional LC with UV, PDA or Fluorescence detection or GC/MS to measure polar pesticides in food matrices and in the environment. Many of these pesticides are not very volatile and have to be derivatized

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.

SPECTRO Analytical Instruments, a leading supplier of analytical instruments for optical emission and XRF spectrometry, has introduced the next-generation SPECTRO xSORT handheld energy dispersive X-ray fluorescence (EDXRF) spectrometer.

Accurate, high resolution mass spectrometry has grown ever more important in qualitative and quantitative analyses.

Problem: Mass spectrometry (MS) has become an indispensible technology for the analysis of compounds of biological interest, is widely available and offers rapid and accurate detection with broad applicability.

Stephen Barnes, Ph.D., Professor of Pharmacology & Toxicology and Director of the Targeted Metabolomics and Proteomics Laboratory at the University of Alabama at Birmingham (UAB), talks about the changes taking place in the field of mass spectrometry (MS) as it migrates from the research lab to a clinical environment.
