LEGO MINDSTORMS Fraction Collector: A Low-Cost Tool for a Preparative High-Performance Liquid Chromatography System.
Article in Analytical chemistry, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Preparative high-performance liquid chromatographic (prep-HPLC) systems are used in many research schemes including purifying products from reaction mixtures, fractionating natural product extracts, and isolating compounds. Manual fraction collection from a prep-HPLC is a common method; however, it often lacks the reproducibility of automated fraction collectors due to human error. Automated fraction collectors for prep-HPLC systems can add thousands of dollars to the cost of prep-HPLC and are thus not always available to budgetary constrained research programs. Nevertheless, an automated fraction collector is a tremendous resource for any lab that employs prep-HPLC methods. Using LEGO MINDSTORMS pieces and easily obtained lumber and a steel C-channel, we were able to deploy an automated fraction collector for only a fraction of the cost of a commercial instrument. The programming software allows for a simple interface to create fraction collection programs tailored to individual HPLC methods. This fraction collector can be connected to any LC system and tailored to collect fractions in nearly any size or shaped container. This fraction collector was designed to provide maximum versatility and will make automated fraction collection more accessible to all researchers. The simple interface allows for quickly adapting the fraction collector method to any liquid chromatographic separation, no matter how complex.
