Cheaper, faster, smaller, safer, or more portable — but not a different measurement. Each lead names an operator, a method, and a context, plus the characteristic risk of that operator.
| Operator | Count |
|---|---|
| cut sample volume 10x | 620 |
| cut analysis time 10x | 530 |
| replace a hazardous reagent | 490 |
| miniaturise to chip scale | 410 |
| parallelise the runs | 392 |
| replace operator judgement with a metric | 360 |
| eliminate a separation step | 350 |
| add an in-line blank | 350 |
| make the measurement ratiometric | 330 |
| add a simultaneous second channel | 330 |
| replace with a proxy measurement | 312 |
| reduce the temperature excursion | 290 |
| convert batch to continuous | 280 |
| replace a consumable with a reusable one | 280 |
| multiplex the assay | 270 |
| add an internal standard | 270 |
| replace an expensive component | 250 |
| remove a calibration step | 210 |
| switch reference to differential | 210 |
| use a cheaper detector | 200 |

An operator is infeasible for a category when it contradicts what the method measures — you cannot "eliminate the separation step" from a separation method and still measure the same thing, and a clinical or forensic context forbids a proxy or a cheaper detector where traceability is required.
