ISOLUTE HAX mixed-mode SPE sorbent is based on a combination of strong anion exchange and non-polar chemistries. Acidic drugs are retained by two primary retention mechanisms. This allows a rigorous interference elution regime to be used to elute interferences retained by either non-polar or anion exchange interactions alone. Only analytes with both non-polar and acidic characteristics are extracted usign the ISOLUTE HAX sorbent, providing an extremely pure final extract.

1.We have developeda general method for synthesizing Diaryl Ethers from both electron richand electron deficient phenols.
2.We have showedthat with our instrumentation we have removedscalabilityas alimiting factor for the ”bench” chemist.
3.We have also developeda new cooling technique on the Advancer that dramaticallyshortens coolingtimes. For ethanol: 180 ºC to 70 ºC within less than 10 seconds..

The trend pharma industry is clearly to speed up the process from lead identification to selection of candidate drug. One of the major limitations is the availability of larger amounts typically hundreds of grams, of the potentially active substance to be further investigated

This poster describes a simple but effective method for screening a range of pesticides and drugs of abuse from liver samples. Liver tissue is homogenized using the Biotage® Lysera, and the subsequent extract is cleaned up using ISOLUTE SLE+ supported liquid extraction columns.

The use of palladium-catalysts in the synthesis of fine chemicals, pharmaceutical intermediates and active pharmaceutical ingredients (APIs) has become quite common in the last few decades. The number of palladiumcatalyzed reactions (both achiral and chiral) available to chemists has provided access to more complex structures in fewer steps and with less waste. An unfortunate side effect of using palladium is the potential for palladiumcontaining impurities to remain in the desired compound after isolation. This is an especially significant problem for the pharmaceutical industry since there is a low limit for heavy metal impurities allowed in the drug substance.

Here we present the separation capabilities of a new type of designed adsorbent, RENSA® Boronate. This new resin has affinity for diols and α-hydroxycarboxylic acids and is able to extract those target compounds with high efficiency and selectivity.

• Solid-Phase Peptide Synthesis (SPPS) is still often
faced with difficulties in the assembly of long and
‘difficult’ sequences, e.g. due to aggregation and
steric hindrance giving rise to incomplete reactions.
These problems have only partly been solved by
new coupling reagents and solid supports.
• Precise microwave heating has emerged as one
new parameter for SPPS, in addition to coupling
reagents, resins, solvents etc.

This poster includes a simple Load-Wash-Elute solid phase extraction method using EVOLUTE EXPRESS WCX, for extraction of aminoglycoside antibiotics from a range of meat, milk and egg samples.
The sample preparation method is automated using Biotage Extrahera, with fast, sensitive analysis utilizing HILIC-MS/MS with MRM Spectrum Mode for ID confirmation (Shimadzu LCMS-8060).

PS-TsNHNH2 and ISOLUTE® Si-TsNHNH2 are solid supported equivalents of p-toluenesulfonyl hydrazide. These reagents are both excellent scavengers for aldehydes and ketones and are generally used in threefold excess with respect to the limiting carbonyl species. A catalytic amount of acetic acid (5-10%) may be required for ketones, hindered substrates or for scavenging in certain solvents (e.g. DMF).
