spectraspectroscopyNuclear magnetic resonance spectroscopy or NMR is a chemical instrument that can be used to evaluate the structure of a chemical compound other than FTIR, GC-MS, and HPLC. NMR spectroscopy commonly used for compound analysis is 1H-NMR and 13C-NMR. Techniques can be used to ...
Explain what a flame test has to do with spectroscopy. What is spectroscopy? What are the different methods of spectroscopy? What fragments might you expect in the mass spectra of the given compound? What fragments might you expect in the mass spectra of the compound below?
You have been introduced to simple concepts on how to read a chromatogram. Please let us have your comments on the article and if you found it useful. Categories:Chromatography Dr. Deepak Dr Deepak Bhanot is a seasoned professional having nearly 30 years expertise beginning from sales and produ...
The mass spectrum is used to identify the components by comparing each to reference libraries of over 275,000 unique spectra. To quantify compounds within the analyzed sample, analysts establish a standard curve of known concentrations of each material. With this highly refined process, GC/MS analy...
The transcriptomes of several cyanobacterial strains have been shown to exhibit diurnal oscillation patterns reflecting the diurnal phototrophic lifestyle of the organisms. The analysis of such genome-wide transcriptional oscillations is often facilitate
GC chromatograms and MS spectra were analyzed in XcaliburTM Software (Thermo Fisher Scientific). Statistical analysis The obtained results were subjected to statistical analysis using the STATISTICA V.13.1 program. A one-way analysis of variance was performed using the NIR test with a significance ...
Sexual selection theory predicts that males are limited in their reproductive success by access to mates, whereas females are more limited by resources. In animal-pollinated plants, attraction of pollinators and successful pollination is crucial for reproductive success. In dioecious plant species, mal...
. To study the community-wide resource space and metabolite turnover, we measured metabolite levels by an untargeted approach using gas chromatography (GC) coupled with mass spectrometry (MS) (Supplementary Data3). In total, 89% (58 of 65) of the identified metabolites could be linked to ...
ADAP-GC is an automated computational workflow for extracting metabolite information from raw gas chromatography mass spectrometry (GC/MS) metabolomics data. Deconvolution of co-eluting analytes is a critical step in the workflow and the underlying algorithm has proven to perform similar or better than...
