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.

Mephedrone (MCAT) is a ‘designer drug’ synthesised to mimic the amphetamine class of compounds. Due to its perceived ‘ecstasy like’ effects of euphoria, excitement and alertness combined with ease of availability, this (until recently) unregulated drug (legal high) has found widespread abuse in the UK in recent years. Harmful effects associated with mephedrone are still being studied but after several deaths were linked to the abuse of the drug, the UK Government made this a Class B substance. Mephedrone extraction was evaluated on three mixed mode cation exchange SPE sorbents: EVOLUTE® CX, EVOLUTE® WCX and ISOLUTE® HCX.

Biotage metal scavengers are a more effective alternative to traditional carbon batch adsorption processes. They have the lowest metals content, and also excellent extractable profiles, therefore not likely to risk contamination, unlike competitive materials we tested. Furthermore, Biotage metal scavengers offer volumetrically, a much more compact solution than carbon, requiring 48 times less volume for the same degree of Pd removal in our studies.
