Traditional RP-HPLC techniques not always critical because improvements in solid-phase peptide synthesis techniques over the years (microwave heating and ChemMatrix® solid phase supports) have reduced the burden on downstream purification steps. Mass directed flash purification can be a viable alternative to more expensive (and lower capacity) semi- or prep-scale RP-HPLC methods.
Isolera Dalton identifies compounds by mass in real time during flash separation, leading to greater confidence in purification, higher purity, greater recovery, and a significant saving in time. Reduce or eliminate the need for time consuming off-line mass analysis during development programs, increase throughput and effectiveness for both chemists and analytical groups.
The Isolera ELSD (evaporative light-scattering detector) is a universal detector designed for use with Isolera flash purification systems when purifying organic compounds that
are undetectable UV or visible light. Flash chromatography with detection and fractionation is now possible when purifying carbohydrates, steroids, lipids, terpenes and other UVtransparent compounds.

The Isolera leak detection system is designed with safety in
mind. Unlike vapor sensing devices with unreliable solvent
vapor sensitivity, the Isolera leak detector’s sensitive,
solvent-resistant refractive index (RI) monitor rapidly
signals the Isolera flash system to stop pumping if any
liquid, volatile or non-volatile, is detected thus protecting
the chemist, system, and lab from potential hazards.

The introduction of parallel synthesis in pharmaceutical R&D has resulted in the need for purification systems
that allow for increased throughput. With reactions being carried out in a microplate footprint, it is important that the reaction workup can also be performed in this way.When using the 96-well format, there are limitations on both the reaction scale and also the sorbent capacity for the purification step. Using a 24-well system allows for greater sorbent masses to be utilized, increasing the scale of purification.

Sample preparation techniques such as protein precipitation, supported liquid extraction or non-polar SPE may not be selective enough to give extracts of sufficient purity for low level analysis. In these cases, the selective mixed-mode approach to the extraction of basic and acidic drugs is a suitable alternative, giving very high purity extracts with minimal levels of co-extracted material.
