The quantification of oligosaccharides using liquid chromatography-electrospray ionization-mass spectrometry (LC-ESI-MS) essentially followed previously described protocols [ 17, 18].
The theory and details including the Intralipid particle radius and refractive index were described in the original derivation [ 59] which has been extensively used for quantification of Intralipid-based liquid phantoms [ 2, 7, 57, 60, 61].
This work deals with the quantification of the bubble-liquid CO2 transfer rate coupled with chemical reactions in the liquid phase.
The synthesized composite nanorods were applied for the detection and quantification of phenyl hydrazine in liquid phase.
A correct quantification of chromatographic peaks in liquid chromatography requires well resolved signals in a proper analysis time.
For quantification of ODS products, upper liquid layer (n-hexane) was withdrawn and analyzed for S by the Analytik Jena AG Multi EA 3100 Element Analyzer.
To confirm the glycerol conversion determined by gas chromatography of liquid samples, the quantification of NH3 released during the reaction was also carried out for few experiments.
Then, the separation and quantification of analytes were performed by liquid chromatography coupled to tandem mass spectrometry (LC MS/MS).
In addition, we investigated the applicability of the proposed method for the quantification of furan in solid and liquid food samples.
In the last place, separation and quantification of analytes were performed by liquid chromatography with fluorescence detection (LC FD) and gas chromatography coupled to mass spectrometry (GC MS).
Targeted quantification of NA and DMA by liquid chromatography mass spectrometry (LC-MS) from root metabolite extracts collected after one week of Fe deficiency identified that concentrations of DMA (average 1.42-fold higher, p ≤ 0.001), but not NA (average 1.05-fold higher, p = 0.988), were significantly higher in the Fe-deficient roots (Fig. 3a and b, Additional file 2: Table S2A).
