MCSGP

Summary

MCSGP avoids the manufacturing bottlenecks of standard preparative chromatography

MCSGP (Multi-column Counter-current Solvent Gradient Purification) is a superior alternative to the preparative batch purification which is normally used in manufacturing of peptides and oligonucleotides. MCSGP is a continuous purification process integrating automated side-cut recycling & in-line dilution between two identical columns (See the MCSGP process principle). The automated side-cut recycling greatly increases yields and eliminates extra re-chromatography runs often done in batch manufacturing to improve yield. MCSGP also reduces the QC burden by eliminating the need for fractionation & mock pool QC analysis for every batch run. Instead, only the product pool is analyzed for quality. Altogether, MCSGP improves manufacturing efficiency, process economics and environmental sustainability.

MCSGP increases process yields without sacrificing purity or productivity

MCSGP helps achieve environmental sustainability goals through process intensification

MCSGP can help minimize environmental impacts because it is both leaner and more intensive than preparative batch chromatography. MCSGP boosts process yields, eliminates inefficient re-chromatography runs, and greatly reduces analytical QC burden in a GMP environment. Together these advantages allow for a significant improvement in overall process economics and environmental benefits due to a significant reduction in material and labor requirements. Firstly, less feedstock is required for the same product output; secondly, no side-cut re-chromatography leads to savings on custom storage bags, dedicated storage space & analytical QC support; Thirdly, far fewer in-process control (IPC) samples are generated in MCSGP, lowering the QC burden and speeding up batch release times. 

MCSGP eliminates re-chromatography steps with automated side-cut recycling

MCSGP Case Studies (ppt)

MCSGP allows real-time batch release by greatly reducing QC burden

MCSGP allows more projects to be accomplished

MCSGP allows 24/7 operation with minimal supervision

AutoPeak dynamic control compensates for cycle-to-cycle variability in MCSGP

AutoPeak dynamic control facilitates robust MCSGP operation

AutoPeak (dynamic process control) automatically triggers MCSGP product collection & recycling based on UV or conductivity thresholds. This facilitates dynamic adaptation to cycle-to-cycle retention time variability and means robustness can be designed into the MCSGP process.

  • Consistent recycling & product collection position

  • Consistent product quality 

  • Robust continuous process operation

  • Counteracts variability in:

    • temperature

    • Solvent quality

    • conductivity, pH

    • Column variability (bed height, aging, packing quality)
