General description
Sample Matrix Compatibility: Organic or aqueous solutions
- A polymerically bonded, benzene sulfonic acid functional group, pKa (< 1.0)
- Counter ion is H+
- Silica support allows for use with very organic solvents (no shrinking/swelling)
- Excellent capacity (0.8 meq/g) for cleaning up solution phase combinatorial chemistry reactions (removing target molecules from reaction by-products and excess reagents)
- The presence of the benzene ring offers some mixed-mode capabilities (hydrophobic interactions) that should be considered when extracting cations from aqueous matrices

How to Find a Lot/Batch Number for COA
Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.
Aldrich Products
For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').
For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').
For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.
Not Finding What You Are Looking For?
In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.

Protocols
Melamine was extracted from milk using Supelco® Discovery® DSC-SCX SPE tubes. Analysis was performed by HPLC, using an Ascentis® Express HILIC column.
Retention occurs through polar interaction between the sorbent and analytes. Typical sample matrices that can be employed in normal-phase SPE include hydrocarbon or fatty oils diluted in a solvent like hexane, isooctane, chlorinated solvent, THF, diethyl ether, or ethyl acetate.
Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
