Advanced bioanalytical techniques like LC/MS/MS and GC/MS are meeting the increasing demand for greater speed and specificity in toxicological screening. But conventional sample preparation methods have not kept pace. In particular, solid phase extraction (SPE), an essential step in the analysis of many biomolecules, has become a through-put limiting step in many laboratories.
The RapidTrace+ is a robust automated platform for quickly developing rugged, reliable SPE methods in regulated
pharmaceutical, clinical and forensic laboratories. The RapidTrace+ eliminates SPE bottlenecks so you can realize the
full benefits of today’s powerful analytical instruments.

Pure fractions are in high demand – impurities mean more work after purification. With new technology, fraction purity can be digitally analyzed directly during chromatography to reveal any problems on the fly. In this application we will show how the Isolera Spektra is used to determine fraction purity, eliminating the need for other post-purification analysis.

Our TurboVap II customers have been successful obtaining excellent recoveries for all semivolatile organic compounds (BNA, PAH, PCB, Pesticides, TPH/DRO, Herbicides). There are many factors that can impact the recoveries, such as client sample matrix, temperature, humidity, and extraction solvents. After gathering information from our customers, we have developed the guidelines below that will help your laboratory determine its optimum conditions for the TurboVap II.

We detail here the application of new column technology to purify histamine and serotonin (Table 1) in one extraction method with the elimination of the sorbent conditioning and equilibration steps familiar to traditional solid phase extraction (SPE) method protocols prior to measurements by ultra performance liquid chromatography-electrospray ionization-tandem mass spectrometry (UPLC-MS/MS). A secondary goal of combining two LC methods into one method was also achieved.
EVOLUTE EXPRESS cation exchange (CX), weak cation exchange (WCX) and acid-base-neutral (ABN) sorbents in a 96 well plate format prior to analysis by UPLC-MS/MS.

One very common transformation in organic synthesis is the reduction of aldehydes or ketones to the corresponding primary or secondary alcohols (Scheme 1) using sodium borohydride as hydride donator. This reaction generally generates the product in very high yield. Among the draw-backs are long reaction times, that a large excess of reagent is needed and that the reaction mixture must be extracted in order to separate the inorganic salts from the product.

In this example, Isolera™ Dalton was used to fractionate completely non-UV absorbing starting materials and products from a classic reductive amination reaction. A resin bound cyanborohydride reagent was used to greatly facilitate the work flow by eliminating the need for traditional work-up, and the mixture applied to flash chromatography purification methods.

MIP Technologies AB (a subsidiary of Biotage AB) has developed
a new type of affinity resin, RENSA® Boronate (Figure 1)
with selective boronic acid surface functional groups. It has
an optimized distribution and accessibility of hydrophobic
(phenyl) and selective boronic acid moieties (Figure 2). It is
produced by a proprietary particle synthesis technology and
exhibits a material architecture and pore size distribution that is
optimized for binding of small and oligomeric molecules.

RENSA® OH is a highly cross-linked methacrylic polymeric
resin in bead form. The porosity is optimized to
allow access to small organic molecules and also oligomeric
compounds. The resin is rigid due to the high degree of crosslinking and has a hydrophilic surface character due to abundant hydroxyethyl functional groups on the polymer backbone. MIP
