Mass-Directed Purification with puriFlash® MS

Integrated Mass Spectrometry for Flash and Preparative Chromatography

Modern purification workflows require faster decision-making, higher selectivity, and reduced manual analysis. Traditional fraction collection based solely on UV detection often leads to unnecessary solvent evaporation, extended analysis time, and reduced efficiency.

Mass-directed purification provides a smarter approach. By integrating a compact mass spectrometer directly with your flash or preparative chromatography system, fractions are collected only when the target molecular mass is detected.

The puriFlash MS systems from Interchim Purification Systems enable precise, automated purification using real-time mass detection, delivering improved productivity and higher confidence in compound isolation.

What Is Mass-Directed Purification?

Mass-directed purification combines chromatography with mass spectrometry to trigger fraction collection based on molecular weight rather than UV signal alone.

This approach allows:

• Selective collection of only the target compound

• Reduced solvent handling and drying steps

• Faster purification cycles

• Higher purity fractions

• Less manual intervention

The result is a more efficient, reliable, and automated purification process.
