Where Does the Greatest Responsibility Lie for Greener Methods?

At analytica 2026 in Munich, Germany, LCGC International spoke with Sébastien Rolle from Shimadzu Europa GmbH about his presentation, "Make Chromatography Greener: Is Less Solvent the Way Forward?"¹

In this video interview, Rolle answers the following question:

• You outline four levels at which instrument manufacturers can impact sustainability — in your view, where does the greatest responsibility lie, and do you think the industry is moving fast enough on all four fronts?

According to Rolle, the four levels where instruments providers could have an impact on sustainability are:

1. Instrument manufacturing; reducing raw materials/energy consumption and CO₂ emission
2. Supporting internal initiatives to promote and support internal (employee and subsidiaries) initiatives to improve sustainability
3. Supporting people and companies that are working on new energies/technologies (batteries, green chemistry/hydrogen) with knowledge, and even developing new instruments or technologies if needed
4. Designing instruments to reduce their impact on their daily use and life in the lab.

Rolle argues that the greatest leverage lies in instrument design itself. The choices made at the design stage cascade through every subsequent phase of a product's life, determining solvent and gas consumption, energy draw, and the feasibility of greener methods for the end user. Manufacturing these instruments demands substantial quantities of energy alongside critical raw materials, including polymers and rare earth elements. Once in routine laboratory use, they frequently rely on organic solvents or gases as mobile phases, producing effluents and waste streams that pose risks to both human health and the wider environment. The energy required to run these instruments adds a further burden, one that is compounded in countries where electricity generation remains heavily dependent on fossil fuels.²

Sébastien Rolle is Market Manager Green Transformation at Shimadzu Europa GmbH, with expertise in green chromatographic methods including supercritical fluid extraction (SFE) and supercritical fluid chromatography (SFC).
