Baseline Noise in High-Performance Liquid Chromatography with Electrochemical Detection
The chromatographic baseline was converted to power spectrum by Fourier transform to show the frequency dependence of noise. The spectral analysis of chromatographic baseline was made under various experimental conditions for high-performance liquid chromatography with electrochemical detection (HPLC-ECD). From the spectral analysis, it was found easily that a system using a small stroke pump a...
متن کاملA Novel High-Performance Liquid Chromatography Method for Detection of Alginate in Pseudomonas aeruginosa
Background and Objective: The opportunistic pathogen Pseudomonas aeruginosa secrets a capsule-like polysaccharide called alginate which is important for evasion of host defenses, especially in patients with suppressed immunity. Method of alginate determination has an important role in the study of microb...
متن کاملNovel reductive-reductive mode electrochemical detection of Rohypnol following liquid chromatography and its determination in coffee.
Rohypnol (flunitrazepam) has been successfully determined in coffee by high performance liquid chromatography dual electrode detection (LC-DED) in the dual reductive mode. Initial studies were performed to optimise the chromatographic conditions and these were found to be 50% acetonitrile, 50% 50 mM pH 2.0 phosphate buffer at a flow rate of 0.75 mL min(-1), employing a Hypersil C18, 5 μm, 250 m...
متن کاملAttomole catechins determination by capillary liquid chromatography with electrochemical detection.
Attomole quantities of catechins were determined by a capillary liquid chromatography system with electrochemical detection (CLC-ECD) and the system is applied to the determination of catechins in human plasma. The eight catechins: catechin (C), epicatechin (EC), gallocatechin (GC), epigallocatechin (EGC), catechin gallate (Cg), epicatechin gallate (ECg), gallocatechin gallate (GCg), and epigal...
متن کاملLiquid chromatography-electrochemical detection for studying the effects of tetrahydrobiopterin on monoamine neurotransmitters in rat striatum
Tetrahydrobiopterin (BH4) is an essential co-factor in the biosynthesis of monoamine neurotransmitters. A nano-Pt/Pd modified electrode as the electrochemical detector (ED) for high-performance liquid chromatography (HPLC) coupled with microdialysis sampling, is used to explore the effect of administration of BH4 on the monoamine neurotransmitters in the rat striatum. The researches demonstrate...
