00:00:00.400 --> 00:00:06.551
In internal references, review candidates and confirm the standard actually added.

00:00:06.551 --> 00:00:11.024
Check its region, attenuation, hydrodynamic radius and provenance.

00:00:11.024 --> 00:00:16.057
Detecting a signal does not automatically activate a reference.

00:00:16.057 --> 00:00:23.326
If you work without an internal standard, the result must retain that warning.

00:00:23.326 --> 00:00:28.358
This walkthrough uses demonstration settings, not a validated calibration.

00:00:30.358 --> 00:00:36.050
In molecular-weight analysis, review the inversion engine and mass model.

00:00:36.050 --> 00:00:42.879
Changing engine creates a different protocol; it does not rewrite historical results.

00:00:42.879 --> 00:00:49.140
Linear-polymer calibrations do not validate absolute masses of stars or brushes.

00:00:49.140 --> 00:00:55.400
Distinguish measured diffusion, corrected diffusion and apparent mass before comparing samples.

00:00:57.400 --> 00:01:04.804
Open advanced mode only when you need to inspect the grid, regularization and stopping criteria.

00:01:04.804 --> 00:01:11.221
Standard values support a reproducible workflow but do not guarantee convergence or identifiability.

00:01:11.221 --> 00:01:16.650
Do not relax a check merely to obtain an attractive figure.

00:01:16.650 --> 00:01:23.067
Retain the method, parameters, warnings and calculation status in the revision you accept.

00:01:25.067 --> 00:01:28.783
Review probe, calibration, solvent, viscosity and temperature.

00:01:28.783 --> 00:01:42.054
In the principal KK2 protocol, the TTMS reference factor and thermal factor are retained per block and applied together exactly once to the complete axis.

00:01:42.054 --> 00:01:47.894
Do not replace the experimental TBO calibration with a nominal gradient.

00:01:47.894 --> 00:01:53.733
This video shows where to inspect conditions without recalculating original data.
