Rudolf Krska on Mycotoxin Analysis Using LC–MS–MS
Mycotoxins are an important group of secondary metabolites produced by fungi that can cause disease in humans and animals. Rudolf Krska from BOKU, IFA-Tulln in Vienna, Austria, talks about how to detect multiple mycotoxin biomarkers using LC–MS–MS and the importance of the approach in developing countries. |

Paired Ion Electrospray Ionization for Trace Anion Analysis
Over the last 10 years, LCGC Blogger Kevin Schug has pursued the development and application of MS-based methods to study noncovalent interactions. The one question that always arises is “Does the electrospray ionization (ESI) process effectively preserve the solution equilibrium, such that the measured relative ion intensities for free unbound and complex ion forms are indicative of relative solution-phase equilibrium concentrations for these species?” |

News: Diagnosing Diabetes Using Amino Acid Profiling of Hair
Profiling amino acids in scalp hair could aid the diagnosis of type 2 diabetes according to a new study. Researchers performed gas chromatography–mass spectrometry (GC–MS) on hair samples taken from diagnosed patients and healthy patients to show that type 2 diabetes alters the amino acid composition of hair's main building block, keratin, and that this biomarker could aid diagnosis in the clinic. |
