| Study ID | ST000892 |
| Study Title | Comparison of T2 filters for quantification of small molecules in plasma by 1D NMR |
| Study Type | NMR development for metabolomics |
| Study Summary | A pooled plasma sample obtained from Red Cross has been seperated into 20 samples. 10 of them were simply mixed with a D2O phosphate buffer, while the other 10 were centrifuged first, then dried and resuspended in a 90/10 H2O/D2O phosphate buffer. The 20 NMR samples were analysed by NMR (4 spectra per sample, but different pulse sequences and parameters were used for each group). Standard addition was used in order to measure the concentration of 5 metabolites: valine, lactate, glucose, phenylalanine and formate. |
