For MR relaxometry purposes we offer the following aqueous solutions of manganese chloride, leading to the nominal relaxation times bellow:

| MNCL‑0480 | 0.480 | 260 | 27 | 306 | 20 |
| MNCL‑0630 | 0.630 | 191 | 19 | 236 | 15 |
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 traceable characterisation. All materials contain a highly effective, broad-spectrum preservative.
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, with the nominal concentrations below. These are all characterised by NIST, providing measurement of ADC, T1 and T2 at temperatures of 0, 16, 18, 20, 22, 24, 26, and 37 °C, and a field strength of 3.0 T.
| Order Code | PVP Concentration (% by weight) | NiCl2 (mM) | ADC at 0°C | ADC at 20°C |
| 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 |
