00:00:00,250 --> 00:00:07,694
The probe study is independent of the active analysis. In this
simulation, we search near four point seven parts

2
00:00:07,694 --> 00:00:12,787
per million using a fixed local window and monitor each
spectrum's original maximum.

3
00:00:13,787 --> 00:00:21,474
Six groups remain visible: three usable ramps and three
diagnostic rows. Calculate all slopes lets us compare

4
00:00:21,474 --> 00:00:28,257
the fits while each acquisition retains its conditions. Review
the chosen calibration row without averaging

5
00:00:28,257 --> 00:00:30,518
different diffusion times or ramps.

6
00:00:31,518 --> 00:00:39,816
Refine R² targets 0.9999 while retaining enough points and
gradient range. This example proposes twenty-two

7
00:00:39,816 --> 00:00:47,560
points instead of twenty-three, excluding point eleven. The
proposed selection still needs your review.

8
00:00:48,560 --> 00:00:55,696
Apply selection changes the included points for this row and
invalidates its previous calibration. Measured

9
00:00:55,696 --> 00:01:02,831
values remain unchanged. Review the slope and conditions, then
evaluate the reference again before saving.

10
00:01:03,831 --> 00:01:11,243
Undo refinement restores the previous selection. This screenshot
follows the real undo action, with all

11
00:01:11,243 --> 00:01:18,654
twenty-three original points included again. An optimized R² does
not demonstrate a physically valid probe

12
00:01:18,654 --> 00:01:19,148
calibration.

13
00:01:20,148 --> 00:01:26,920
The simulation uses pure water at twenty-five degrees Celsius and
a compatible literature diffusion coefficient.

14
00:01:26,920 --> 00:01:34,595
Evaluation derives the gradient from the reviewed fit and
conditions. This demonstration does not save or share

15
00:01:34,595 --> 00:01:35,950
an experimental probe.
