Traditional liquid-liquid extraction, carried out in vials, can be difficult to automate. ISOLUTE Array
HM-N plates for supported liquid extraction offer an easy to automate alternative to this popular sample
preparation technique, eliminating the need to physically separate immiscible layers. Each step is a
simple liquid transfer or addition, and no mixing is required.

This method selection guide is designed to minimize the choices required to optimize the Supported Liquid Extraction method. The buffer and solvent suggestions provide a range of pHs and solvent polarities for acidic, neutral and basic drugs of varying pKa and logP values. The selections are based on extensive work in Biotage’s R&D Laboratories.
This guide describes how to develop supported liquid extraction methods using ISOLUTE® SLE+ products, along with hints and tips for optimizing performance and extending the range of analytes that can be extracted

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.

This Chemistry Data Sheet provides procedures for both the automated and manual fractionation of EPH in soil. The
automated procedure is described on page 2 and the manual procedure is outlined on page 3. Chromatograms
illustrate the ability of ISOLUTE EPH to provide efficient fractionation of hexane or pentane soil extracts into
aliphatic and aromatic fractions (see Appendix).

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.

Non-polar SPE is commonly used for extraction of acidic, neutral and basic drugs from biological fluids. It is particularly useful when a parent drug and metabolites of different functionalities are to be extracted simultaneously, and will provide cleaner extracts than alternative sample preparation techniques such as protein precipitation.

ISOLUTE PLD+ plates remove >99 % of plasma proteins and phospholipids, the main causes of ion suppression, leading to cleaner extracts and increased sensitivity (signal-to-noise
(S/N)) for a broad range of analytes.

Protein precipitation is a routinely used sample preparation technique for removal of proteins from biological fluid samples prior to analysis. Protein precipitation in the 96-well format, using filtration for protein removal, is a high throughput alternative to the traditional centrifugation based technique.
