In conclusion, the comprehensive analysis of blood serum metabolites by NMR using two different sample preparation methods was quantitatively evaluated based on the identification and quantitation of aqueous metabolites.
A H NMR spectrum of a biofluid, such as urine, can be viewed as the sum of its individual metabolites and if acquired under quantitative conditions can be used for both metabolite identification and quantitation.
Furthermore, this technique has a high degree of sensitivity, and the amine specific isobaric reagents permit the identification and quantitation of up to 8 different samples simultaneously16,17.
2DE is a powerful proteomic profiling technique for both protein identification and quantitation; however this traditional method showed some limitations in term of reproducibility.
The complete stereochemistry of resolvin D4 was recently determined,39 and the synthetic standard was used here for identification and quantitation from human milk.
Spectrophotometric and electrochemical detection, nuclear magnetic resonance, and different mass spectrometric methods can be used for their identification and quantitation.
This method employed ultrasound-assisted emulsification microextraction (USAEME) before identification and quantitation of the parabens via on-line acetylation gas chromatography-mass spectrometry (GC MS).
The aim of this study was to develop a method that would provide simultaneous identification and quantitation of genotypes A and D in a single-tube reaction.
The array consists of ten nanostructured silicon microcantilevers functionalized by polymeric and gas chromatography phases and macrocyclic receptors as spatially dense, differentially responding sensing layers for identification and quantitation of individual analyte(s) and their binary mixtures.
The experimental procedure using SPME fibers does not require specific identification and quantitation of individual pollutants and can be used to evaluate wastewater with multiple VOCs.
Lipidomics is the identification and quantitation of changes in the lipidome of a cell, tissue, organ or biofluid in health and disease using high resolution mass spectrometry.
