Your current column and the selected column, shown together.
4 of 8 scoring criteria are comparable, covering 49% of the total weight. Missing values are excluded.
A score requires at least 3 comparable criteria and 50% data coverage.
Similarity does not guarantee identical selectivity or performance. Confirm suitability for your method.

Each comparable criterion earns its weight multiplied by its similarity. The sum is divided by the available weight, then multiplied by 100 and rounded. Missing criteria earn no points and add no weight. Vendor, Brand, Mode, length, internal diameter, pressure and temperature do not contribute to this percentage. Mode and Modification determine which families appear in recommendations.

| Criterion and method | Current column | Selected column | Contribution |
|---|---|---|---|
| Modification Recorded values overlap. Proprietary modifications are capped at 50%; an identical label does not confirm identical chemistry. | Silica/Phenyl | Silica/Phenyl | 100.0% × 25 = 25.00 points |
| Product Usage Shared usage values divided by all distinct usage values recorded for these columns. | Not recorded | Large molecules | Excluded, missing data |
| Carbon Load, % Numeric closeness, falling to zero at a 50% relative difference. | 12.0 | Not recorded | Excluded, missing data |
| Endcapping Recorded endcapping values overlap. | Yes | Yes | 100.0% × 10 = 10.00 points |
| Pore Size Numeric closeness, falling to zero at a 50% relative difference. | 70 | 300 | 0.0% × 10 = 0.00 points |
| Surface Area Numeric closeness, falling to zero at a 50% relative difference. | 300 | Not recorded | Excluded, missing data |
| pH Stability The overlapping pH range divided by the combined pH range. | 2.0 to 8.0 | Not recorded | Excluded, missing data |
| Particle Size Numeric closeness, falling to zero at a 20% relative difference. | 5.0 | 5.0 | 100.0% × 4 = 4.00 points |
