Oftentimes, aqueous samples collected contain varying amounts of suspended solids or sediment strictly due to either the source of the water being sampled or improper sampling techniques. In any circumstance, samples with high amounts of particulates or sediment have proven challenging to extract using EPA Method 3535 Solid Phase Extraction (SPE).

Dioxins are of great environmental concern due to their teratogenic, mutagenic, and carcinogenic impact. These lipophilic compounds bioaccumulate in humans and wildlife and can have half lives of up to 132 years, making them persistent organic pollutants (POPs). Traditional SPE requires a filtration step to remove particulates when using SPE cartridges, because of clogging issues.

Peptide purification using standard reversed phase HPLC methods are hampered by low loading capacity, resulting in purifications that demand significant time investment. Recently, the use of reversed phase flash chromatography has increased in popularity for peptide purification due to the significant reduction of purification time,
enabled by the increased loading levels of the larger stationary phase particles. Resolution, though, is somewhat diminished with the larger particle size, demanding creative techniques to retain a highly pure peptide product.

In medicinal chemistry, organic synthesis will generate by-products with similar chemistry to the product. Separating these impurities from the product often becomes a challenge that often only prep HPLC can achieve.
In this poster, we discuss how using sample dry loading with a cation exchange scavenger media with flash chromatography
improves product purity by removing many of the impurities.

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.
