Your current column and the selected column, shown together.
4 of 8 scoring criteria are comparable, covering 54% of the total weight. Missing values are excluded.
The percentage includes partial similarity. Green means the recorded values match; red means they differ. The calculation below explains each contribution.
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/C18 | Silica/C18 | 100.0% × 25 = 25.00 points |
| Product Usage Shared usage values divided by all distinct usage values recorded for these columns. | Acidic compounds, Moderately polar compounds, Polar compounds | Not recorded | Excluded, missing data |
| Carbon Load, % Numeric closeness, falling to zero at a 50% relative difference. | 12.0 | 13.0 | 84.6% × 15 = 12.69 points |
| 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. | 150 | Not recorded | Excluded, missing data |
| Surface Area Numeric closeness, falling to zero at a 50% relative difference. | 200-220 | Not recorded | Excluded, missing data |
| pH Stability The overlapping pH range divided by the combined pH range. | 0.8 to 7.5 | Not recorded | Excluded, missing data |
| Particle Size Numeric closeness, falling to zero at a 20% relative difference. | 5.0 | 3.0 | 0.0% × 4 = 0.00 points |
47.69 ÷ 54 × 100 = 88% (rounded).
