Scientists from CEITEC Masaryk University are collaborating with clinicians from the Department of Respiratory Diseases and TB at the University Hospital Brno (Brno, Czech Republic) to improve the diagnosis of cystic fibrosis, specifically in newborn babies. In a new study published in the Journal of Chromatography A, a new "skin wipe" sweat sampling method is presented that reduces the time required for sampling to under a minute and utilizes capillary electrophoresis (CE) to simultaneously determine chloride, sodium, and potassium ions in sweat samples.

Liquid chromatography coupled to triple quadrupole tandem mass spectrometry (LC–MS–MS) in multiple reaction monitoring (MRM) mode is widely considered as the gold standard for pesticide analysis. In this article recent developments in LC–MS–MS technology to meet increasing regulatory demands and productivity targets in quality control and contract laboratories are explored.

To understand how the HPLC system works, it can be useful to first identify the basic components of virtually every system. Armed with that information, envisioning the HPLC system as comprised of three different zones - each with unique characteristics and each with its own set of requirements - can offer further guidance.
