puriFlash®-CMS
Mass-Directed Purification
Your purification workflow simplified: Experience Mass Directed Purification your way on both Flash & PrepLC systems
Reduce your purification workload up to 50% with the specificity of mass detection, no more fraction guesswork
Time is precious in the lab. With mass-directed purification, chemists get pure compounds faster and with fewer steps—saving hours each week. Advion Interchim Scientific® already offers the industry-leading PrepLC-MS integration, and now seamlessly integrates our Flash purification offerings as well. With the puriFlash® XS 530 coupled with the expression® Compact Mass Spectrometer (CMS) you can:
- Mass spectrometry allows simultaneous purification and compound characterization with mass-directed fraction collection
- Collect only your peaks of interest
- Reduce or eliminate the need for fraction analysis with confidence,
knowing you collected your peak of interest - Reduce the burden of drying down unnecessary fractions
The puriFlash®-CMS offers the benefits of compact mass spectrometry (CMS) for in-line, mass-directed fraction collection, providing users a more sensitive and accurate measure of fractions in real-time and a reliable detection method even when the analyte lacks a chromophore.
The technology unambiguously identifies residual starting materials, desired product ions, side reactants and impurities by their molecular weight even in the presence of co-eluting compounds and solvent peaks. Offering both APCI or ESI ionization with positive and negative polarity, the addition of a mass spectrometer should be something every chemist should consider for the ultimate purification solution.
Mass directed fraction collection greatly speeds up the chemist’s workflow with confidence in the content and purity of the collected fractions by eliminating off-line TLCs, workup, and core lab LC/MS assays.
- Unique MS-interface design with a dynamic split and dilution valve for high flow rates and all column sizes without generating backpressure
- Integrated post-split dilution to adjust the concentrations used in the MS source (no concentration limit – no signal saturation)
- Normal & Reverse Phase
- Normalized Scale signals MS, UV, ELSD (6 acquisition signals)
