The SPE-Z Prep Manifold (PN SPZ-0250) is designed for high productivity disk solid phase extraction (SPE) work. It is an excellent first step into SPE for a laboratory moving away from less efficient liquid-liquid extraction for the extraction of semi/nonvolatile analytes and Oil & Grease from a water sample.

This Chemistry Data Sheet describes the use of ISOLUTE® HM-N as a support material for pre-absorption of a
reaction mixture prior to flash chromatography. This approach is used as a solution to loading reaction
mixtures that are only soluble in polar solvents onto an ISOLUTE Flash SI II or Flash NH2 column.

ISOLUTE HM-N is a modified form of diatomaceous earth that can efficiently absorb aqueous samples. ISOLUTE HM_N is chemically inert and stable in the pH range 1-13. These characteristics make it a versabile material that plays an important role in many sample preparation applications.

In order to obtain a fast synthesis of an N-unprotected tripeptide, microwave (mw) assisted deprotection, coupling and partial deprotection were applied starting with a purified protected dipeptide [Fig. 1]. The three consecutive mw assisted steps were performed without any intermediate purifications and were accomplished within some 30 minutes. The resulting crude mixture containing the Boc deprotected tripeptide ester was shown to be quite complex [Fig. 2]. The crude product was subjected to automated reversed phase flash chromatography, followed by automated fraction pooling and “thin film evaporation”. The total time for the entire procedure was 1 h 20 min. The purity of the product was > 99%.

Customer Case: Japan Frozen Foods Inspection Corporation.
The Japan Frozen Foods Inspection Corporation (JFFIC) made the transition from traditional mouse
testing of shellfish toxins, to instrumental analysis by developing original methods. In the sample
preparation procedure JFFIC uses EVOLUTE® ABN hydrophilic/hydrophobic SPE columns from Biotage.

Trityl-ChemMatrix is mainly used to obtain a protected peptide as is has very low TFA cleavage conditions (under 1%). This resin therefore has the same cleavage conditions as the Cl-Trityl-polystyrene. On request, Trityl-ChemMatrix resins can
be offered preloaded will all 20 natural amino acids. Other amino acids can be preloaded on special request. Please take note that the Cl-Trityl-ChemMatrix resin is not offered for stability reasons. It is most effective to start with the Trityl-
OH-ChemMatrix resinchlorinate the resin and then add the amino acid of desire.
