The first peer-reviewed PC/PPQ framework for MCSGP. 95% IPC reduction, 73% PMI reduction, 96% gross-to-gross yield — validated at GMP commercial scale on Bachem Bivalirudin.
Eisenhuth, R. & Müller-Späth, T. — Processes, 2025 (Open-Access)
First peer-reviewed AIEX MCSGP for therapeutic siRNA. Yield improved from 80% to 93% on a sugar-conjugated siRNA sense strand — software-aided method development enabled fast batch-to-MCSGP transfer. Throughput increased 87%.
Weldon et al. Org. Process Res. Dev. 2025, (Open-Access)
Proof-of-concept MCSGP for AAV2 polishing. Full capsid content increased from 30% to 68% (ddPCR) after six cycles — with +20.6% yield, +23% productivity, and 27% reduced buffer consumption vs batch AEX. AutoPeak® PAT validated against cryo-TEM and ddPCR.

ChromaCon’s modeling services support and accelerate MCSGP process design and scale-up of oligo and peptide purifications
Purification is where oligonucleotide yield is lost, and the synthesis has to be sized to cover it. Converting a reversed-phase batch method for a GalNAc-conjugated gapmer to twin-column MCSGP lifted recovery from 52.7% to 91.6% at the same purity — enough to shrink the synthesis step by 42.5% for the same daily output.
An established anion exchange batch method for a conjugated siRNA sense strand, converted to continuous twin-column MCSGP: 13 cycles, 27 product elutions, and yield up from 80% to 93% at unchanged purity — plus a software-aided route from batch chromatogram to running method.
Continuous chromatography is already in production use, but there was no published account of how to validate it for a regulatory filing. This study provides one, working through Process Characterization and Performance Qualification for MCSGP on commercial-scale Bivalirudin purification: 34 parameters assessed, four tested, one critical.
Green solvents have always cost the peptide industry recovery. This study shows the loss is a property of batch chromatography, not of the solvent: run the same green eluent counter-currently and the yield comes back.
