We aimed to extract mixed DNA samples collected from the crime scene into DNA profiles and provided an accurate assessment of which contributor DNA belongs to the culprit. We analyze the nuclear DNA (nDNA) from DNA mixtures and amplify genes with the GlobalFiler 24 Locus Gene (Thermo Fisher, USA) kit, followed by capillary electrophoresis using the Genetic Analyzer 3500 System.

Since decades, cyclodextrins are one of the most powerful selectors in chiral capillary electrophoresis for the enantioseparation of diverse organic compounds. This review concerns papers published over the last decade (from 2009 until nowadays), dealing with the capillary electrophoretic application of single isomer cyclodextrin derivatives in chiral separations.

Contrast agents are widely used to enhance the image quality in clinical imaging using e.g. ultrasound. The contrast agents used for ultrasound imaging are mainly microbubbles (MBs) with a soft or hard shell encapsulating a core of gas. In the present study, MBs with a hard shell of polyvinyl alcohol (PVA), and a core of air were analysed in a capillary electrophoretic system using a UV area imaging detector.

Consumption of sports drinks is generally associated with a healthy lifestyle, despites a common addition of colorants and preservatives to these products. This work presents the novel methods based on high performance liquid chromatography (HPLC) and capillary electrophoresis (CE), aimed at the simultaneous quantification of both these groups of additives within a single separation.

Novel Psychoactive Substances (NPS) represent an alternative to established illicit drugs. They are traded via the internet and exhibit small alterations in their chemical structure to circumvent law, however, their psychotropic effects are comparable. There is still poor knowledge about side effects and health risks.

The applicability of capillary zone electrophoresis (CZE) for the separation of the deamidated forms of insulin has been studied. 50 mM NH4Ac (pH=9) with 20 % v/v isopropylalcohol was found optimal for efficient separation of insulin from its even 10 deamidated forms.

The first CE methodology enabling the enantiomeric separation of panthenol was developed in this work. Electrokinetic chromatography with cyclodextrins (CD-EKC) was the CE mode employed for this purpose. The effect of different experimental variables such as the nature and concentration of the cyclodextrin.

The performance of an original CE-MS interface that allows the in-axis positioning of the electrospray with respect to the MS inlet was evaluated. The variations in the geometrical alignment of this configuration in the absence of a nebulizing gas afforded a significant reduction in the sheath-liquid flow rate from 3 μL/min to as low as 300 nL/min.

Polyamine metabolites provide pathophysiological information on disease or therapeutic efficacy, yet rapid screening methods for these biomarkers are lacking. Here, we developed high-throughput polyamine metabolite profiling based on multisegment injection capillary electrophoresis triple quadrupole tandem mass spectrometry (MSI-CE-MS/MS).
