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.

Sample preparation techniques such as protein precipitation, supported liquid extraction or non-polar SPE may not be selective enough to give extracts of sufficient purity for low level analysis. In these cases, the selective mixed-mode approach to the extraction of basic and acidic drugs is a suitable alternative, giving very high purity extracts with minimal levels of co-extracted material.

ISOLUTE® Si-Propylsulfonic acid (SCX-2) belongs to a class of strong supported acids. As a bound sulfonic acid, it has a natural propensity to bind alkali and some transition metal group metals, which means that it can be used as a scavenger for metals with a +I or +II oxidation state, such as Na, K, Li, also
Pd, Rh, and Ru.

The ability to synthesize peptides in a range of different
scales is a requirement in many research laboratories. The
Biotage® Initiator+ Alstra™ fully automated microwave peptide
synthesizer has a scale range of 5 μmol up to 2 mmol using
three different reactor vial sizes (5 mL, 10 mL and 30 mL).
The acyl carrier protein fragment, ACP (65–74), H-Val-Gln-
Ala-Ala-Ile-Asp-Tyr-Ile-Asn-Gly-NH2 (VQAAIDYING-NH2) (1), is
a well-known so-called difficult sequence and is commonly
used to evaluate the performance of new synthesis reagents
