Flash chromatography is the primary technology for separating, purifying, and isolating both synthetic organic compounds and natural products. Until recently, automated flash purification systems were limited to user-selected detection and collection wavelengths to fractionate separated compounds from sample mixtures. In this application note we demonstrate how the advances in Isolera Spektra are used in the purification of a spinach extract.

Isolera Spektra provides definitive fraction purity assessment
in both 2-D and 3-D prior to any post flash analysis. With this
information chemists quickly know if a fraction contains a pure
product suitable for further mass and structure confirmation
or whether the impure fractions must be re-purified. This
knowledge improves synthesis throughput and avoids any
embarrassment of submitting impure fractions for analytical

The UV absorption spectrum of some solvents
overlaps with the product they dissolve, meaning
that fraction collection processes cannot distinguish
between solvent and product. Luckily, there is
technology that solves this problem.
Flash purification is a separation technique developed in 1978 by Professor W.C. Still that uses a stationary phase (a column or cartridge filled with an insoluble solid support) and a mobile phase (elution solvent mixture) to separate and purify a mixture of organic compounds.

Interest in peptide-based therapeutics has risen dramatically over the last decade. More specifically, significant energy has been dedicated to cyclic peptides, their synthesis, their biological activity, and their biological stability as potential alternatives to their linear counterparts. However, synthesizing a cyclic peptide creates significant challenges not encountered in linear peptide synthesis.
Herein we present a synthesis of oxytocin describing optimization for fully automated, on-resin disulfide bond formation utilizing Branches™, a unique feature enabling visualization and specific programing for cyclic and branched peptide synthesis. We will highlight the transferability of this optimized synthesis to larger scale syntheses and conclude with the fully automated synthesis of cyclized oxytocin incorporating an isotopically labeled Leu residue, enabling use as an internal standard in MS experiments.

ISOLUTE Confirm HCX columns are based on cation exchange and C8 mixed mode chemistries. Basic drugs are therefore retained by two primary retention mechanisms - ionic and non-polar. This allows a more rigorous interference elution regime to be used, leading to a very clean final extract, as many non-polar interferences which are retained by a non-polar interaction alone, can be eluted selectively, prior to elution of the drug.

It is well known that traditional liquid-liquid extraction (LLE) provides very clean extracts prior to LC/MS analysis. Supported liquid extraction is analogous to traditional LLE, however, analyte partitioning takes place using an inert support material, rather than two immiscible liquids. This provides excellent extraction efficiencies while alleviating many of the tedious liquid handling issues associated with LLE.
