| Samples | % Recovery | Mn (kDa) | Mw (kDa) | Rg (nm) | Rh (nm) | [ƞ] mL/g |
|---|---|---|---|---|---|---|
| EPS-0C | 8.5 | 890 (±35%) | 1400 (± 40%) | 150 (± 5%) | 67 (± 5.1) | 1480 (± 1%) |
| EPS-2C | 73 | 400 (± 0.7%) | 550 (± 2%) | 43 (± 2%) | 26 (± 0.5) | 230 (± 0.4%) |
| EPS-5C | 72 | 340 (± 0.6%) | 550 (± 4%) | 41 (± 3%) | 21 (± 0.6) | 155 (± 0.5%) |
Mw: Weight-average molar mass estimated by SEC-MALLS-DRI. Mn: Number-average molar mass estimated by SEC MALLS-DRI. Rg: Gyration radii. Rh: Hydrodynamic radii. [η]: Intrinsic viscosity.
