Nano-liquid chromatography (Chapter 9)
2023The aim of this chapter is to discuss the main advantages of CLC/nano-LC over conventional LC considering the main features of these miniaturized techniques. Instrumentation, selection of optimum experimental parameters, and some selected applications, published in the period 2017-2021 in various fields, will also be illustrated.

Enantiomeric separation by using nano‐liquid chromatography with on‐column focusing
Journal of Separation Science, 2008AbstractThe present study shows a new nano‐liquid chromatographic method for β‐blocker enantiomers' separation. This method consists of using a capillary column packed with silica particles which were chemically modified with vancomycin. On‐column focusing allowed to inject relatively high sample volumes (1500 nL) increasing method sensitivity.

Nano-liquid chromatography analysis of dansylated biogenic amines in wines
Journal of Chromatography A, 2007In this work, the simultaneous analysis of 10 biogenic amines (ethanolamine, methylamine, tryptamine, 2-phenylethylamine, putrescine, cadaverine, histamine, tyramine, spermidine and spermine) in wines by nano-liquid chromatography (nano-LC) using UV detection and a capillary bidentate C(18) column of 100 microm I.D. is proposed. The 10 selected amines,

Chapter 27 - Nano-Liquid Chromatography
2017This chapter presents the main features of nano-liquid chromatography (nano-LC), its advantages over conventional LC techniques, and some selected applications published in the last 5 years. Nano-LC is the miniaturization of HPLC where the analytes separation takes place into capillary columns of thin diameter (

ELECTROPHORESIS, 2017
In the present study, an attempt was made to achieve separation of enantiomers within a minute in nano‐LC and CEC. In order to achieve this goal several parameters were optimized from the viewpoint of the property of chiral analytes, concentration of the chiral selector in the packing material, capillary dimensions, and separation mode. The enantiomers

Preparation of Monolithic Affinity Media for Nano-Liquid Chromatography Applications
2014In this protocol, a strategy is described for preparing affinity media with monolithic materials as stationary phase, which is exemplified for the biotin-avidin interaction pair. The capillary columns prepared in this manner are compatible with nano-liquid chromatographic conditions.

Analytical Chemistry, 1999
An automated liquid nano-separation system has been developed for nano-liquid chromatography (nano-LC) and capillary electrochromatography (CEC) using both isocratic and gradient elution. One fused-silica nanocolumn, typically 75 μm i.d. × 39 cm (25 cm effective packed length), packed with Spherisorb ODS 1, 3 μm particle size, can be used with either ...

Integrated Nano Liquid Chromatography System On-a-Chip
2006Integrated liquid chromatography (LC) chips are valued because of their significant advantages over conventional systems. However, they are very challenging to build due to the high complexity of LC systems and the need for high-level integration of many discrete microfluidic devices.

Inversion of a nano-Liquid Chromatography dynamical model for quantitative proteomics
IFAC Proceedings Volumes, 2009Abstract This paper presents an adaptive method which enables estimation of protein quantity present in complex mixtures (urine, plasma) analyzed by an LC-MS (Liquid Chromatography and Mass Spectrometry) system. The proposed approach is based on the inversion of a parametric state space model describing the chromatographic column behaviour ...
