Capillary Electrophoresis as a New Tool in Forensic Toxicological Analysis
The basic aspects of capillary electrophoresis (CE) such as: instrumentation, separation modes and its chief domains of use in forensic analysis are presented. Micellar electrokinetic capillary chromatography (MECC), capillary zone electrophoresis (CZE) and chiral separations – the most often used separation modes in drugs analysis – are described. The main directions of development of CE metho...
متن کاملPrinciples, Practice, and Evolution of Capillary Electrophoresis as a Tool for Forensic DNA Analysis.
Capillary electrophoresis (CE) is a versatile and widely used analysis platform with application in diverse areas such as analytical chemistry, chiral separations, clinical, forensics, molecular biology, natural products, organic chemistry, and the pharmaceutical industry. Forensic applications of CE include fragment analysis, DNA sequencing, SNP typing, and analysis of gunshot residues, explos...
متن کاملAutomated extraction of direct, reactive, and vat dyes from cellulosic fibers for forensic analysis by capillary electrophoresis.
Systematic designed experiments were employed to find the optimum conditions for extraction of direct, reactive, and vat dyes from cotton fibers prior to forensic characterization. Automated microextractions were coupled with measurements of extraction efficiencies on a microplate reader UV-visible spectrophotometer to enable rapid screening of extraction efficiency as a function of solvent com...
متن کاملIntegrated portable polymerase chain reaction-capillary electrophoresis microsystem for rapid forensic short tandem repeat typing.
A portable forensic genetic analysis system consisting of a microfluidic device for amplification and separation of short tandem repeat (STR) fragments as well as an instrument for chip operation and four-color fluorescence detection has been developed. The microdevice performs polymerase chain reaction (PCR) in a 160-nL chamber and capillary electrophoresis (CE) in a 7-cm-long separation chann...
متن کاملApplication of Guanidine Hcl to Improve Enantioseparation of a Model Basic Drug, Cetirizine, By Capillary Electrophoresis Using Sulfated Β-Cyclodextrin
A common approach in resolving enantiomers of chiral basic drugs by capillary electrophoresis (CE) is to use cyclodextrins (especially their anionic derivatives) as chiral selector in the acidic buffer (pH ≤ 3) in normal or reversed (carrier) mode. Then, some organic modifiers are added to the buffer solution if the resolution is not satisfactory. In case of cetirizine (CTN), applying the same ...
