T1 and T2 relaxation times are estimated based on NIST reference measurements. The actual relaxation times will vary on a batch to batch basis, however these will be provided based on NIST’s SI traceable characterisation (NIST SP 250-97).
For isotropic diffusion, we provide aqueous solutions of polyvinylpyrrolidone (PVP) K-30, doped with Nickel Chloride so that T1’s and T2’s are not excessively long. Each batch has their ADC, T1 and T2 SI traceably characterised by NIST (NIST SP 250-100) at temperatures of 0, 16, 18, 20, 22, 24, 26, and 37 °C, and a field strength of 3.0 T.
| Order Code | Nominal PVP Concentration (% by weight) | Nominal Nickel Chloride Concentration (mM) | ADC at 0°C (*10-3 mm2/s) | ADC at 20°C (*10-3 mm2/s) |
| PVP‑0000 | 0.0 | 1.0 | 1.10 | 2.02 |
| PVP‑0025 | 2.5 | 0.96 | 1.03 | 1.91 |
| PVP‑0050 | 5.0 | 0.92 | 0.98 | 1.82 |
| PVP‑0100 | 10.0 | 0.83 | 0.83 | 1.59 |
| PVP‑0150 | 15.0 | 0.74 | 0.73 | 1.37 |
| PVP‑0200 | 20.0 | 0.64 | 0.58 | 1.18 |
| PVP‑0250 | 25.0 | 0.55 | 0.48 | 1.00 |
| PVP‑0300 | 30.0 | 0.45 | 0.38 | 0.84 |
| PVP‑0400 | 40.0 | 0.23 | 0.23 | 0.54 |
| PVP‑0500 | 50.0 | 0.0 | 0.12 | 0.32 |
Values listed are based on a batch of manufactured solutions. Future batches may vary.
