Analytical Life Cycle Assessment as a 10-Stage Framework for Evaluating and Improving the Sustainability of Analytical Workflows.
Article in Analytical chemistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Analytical life cycle assessment (ALCA) extends traditional life cycle assessment (LCA) methodology to the unique context of analytical chemistry, clinical diagnostics, environmental monitoring, and forensic testing. Unlike conventional LCA, which focuses on physical products with linear supply chains, ALCA addresses the distinctive environmental, operational, and economic characteristics of analytical workflows. This tool presents a comprehensive 10-stage ALCA framework consisting of sampling, transportation, storage, pretreatment, sample preparation, premeasurement, measurement, waste disposal, assessment, and reporting/decision making. Each stage is defined, its types are described, and its potential impact on the overall analytical process is analyzed. A dual-threshold assessment rubric is introduced, combining absolute benchmarks (green, yellow, and red zones based on best practices) with relative hotspot identification (comparison to the average contribution per stage). Five hypothetical case studies demonstrate the application of ALCA to assess energy consumption, water consumption, carbon footprint, active analyst time, and cost. The case studies show how the dual rubric identifies critical hotspots, guides improvement decisions, and prevents the problem of all stages appearing green, while the total impact remains unacceptably high. ALCA provides a practical, actionable framework for laboratories seeking to balance analytical reliability, practicality, and environmental sustainability in accordance with the white analytical chemistry principle. The tool is freely available for end-users at bit.ly/ALCA2026.
