About Sorpmetrics
For a century, adsorption has been inferred from the liquid: measure how much vanishes from the solution and assume the rest landed on the solid. We weigh the solid itself, in the working liquid, and read the number off directly.
Where it came from
The method grew out of years of crystallography and coordination chemistry in Óscar Castillo’s group at the University of the Basque Country (UPV/EHU). Rubén Pérez-Aguirre was building the porous metal-organic materials there, and he wanted to know what they really held in solution, not what a dry gas-phase test guessed they might hold.
His answer was a force balance. Suspend the particle in a magnetic field, then watch the field shift as mass adsorbs onto it; that shift calibrates into a captured-mass number. It reads the solid in virtually any liquid at normal temperature and pressure — water and ethanol are the proven examples — and it does so independent of particle size, even on materials a dry test would write off as non-porous.
The proof came when CO₂ was captured straight from water and weighed on the solid. After that it stopped being a curiosity and became a measurement worth a company. The same question turns up across pharma, CO₂ capture and CCUS, water and PFAS, membranes, direct air capture, academic labs, and high-throughput screening: what does this solid hold in its working liquid?
Our mission
We make adsorption visible, so the people designing materials can act on a measured number, not a hopeful one.
The people
Chief Technology Officer
The chemist behind the method. Rubén wrote the peer-reviewed papers that establish the force balance, calibrated it in virtually any liquid at normal temperature and pressure (water and ethanol are the proven examples), and showed CO₂ capture read directly on the solid. Both patent families are his.
Scientific Advisor
The chemistry the method reads. A professor of inorganic chemistry at the University of the Basque Country (UPV/EHU), Óscar runs the group that made the porous frameworks at the heart of the work. He is a co-inventor on the patents and advises on the science.
Chief Executive Officer and Business Development
Turns a measurement into a company. Hugo runs the commercial side, from the service catalogue to the partnerships, and holds every page to what the data actually supports.
