Sample Preparation:
| Sampleprep ID: | SP002359 |
| Sampleprep Summary: | 100 µL of 1 M potassium phosphate (KH2PO4), with 0.1% sodium salt of 3-(trimethylsilyl)propionic-2,2,3,3-d4 acid (TSP-d4, chemical shift reference) in D2O were added to 900 µL of wine. The wine samples pH (originally ca. pH 3.5) was adjusted to 3.0 ± 0.03 by adding 5% (v/v) HCl in D2O, and 600 µL of the mixture were transferred into 5 mm NMR tubes. |
| Processing Method: | None |
| Sample Resuspension: | None |
| Sample Spiking: | 0.1% sodium salt of 3-(trimethylsilyl)propionic-2,2,3,3-d4 acid (TSP-d4), as a chemical shift reference |
