Reveleris Amino and Diol
Flash Cartridges
Silica flash cartridges, while effective for many applications, have their limitations for some
compound classes like carbohydrates and lipids. For these applications, Grace Discovery
Sciences has introduced the Reveleris® Amino and Diol Flash Cartridges.
Reveleris® Amino Flash Cartridges
•t Ideal for polar and basic molecules
•t Compounds such as carbohydrates, nitrogen containing heterocycles, amines, etc. which
t exhibit peak streaking and tailing with unbonded silica cartridges.
Reveleris® Diol Flash Cartridges
•t Alternative selectivity to unbonded and reversed phase media
•t Broad application to separate a variety of molecule polarity types including lipids

Bile acid purification during lead generation in drug discovery
Grace Davison Discovery Sciences
Introduction:
Grace Davison Discovery Sciences
Bile acids such as cholic acid are steroidal acids, which occur, in salt form in bile, secreted into the gut to
emulsify fats and encourage digestion. Hepatic conversion of cholesterol into bile acids increases the
breakdown of LDL cholesterol adding value in treatment of coronary patients. Bile acids are starting
materials for the semi-synthesis of other medicinal steroids due to their availability as raw materials.
Conjugation of cholic acid with glycine or taurine increases its water solubility for drug development.

Over the last few decades, green tea has been subjected to many scientific and medical studies to determine the extent of its longpurported health benefits, with research centering on polyphenols, particularly the catechins, in green tea.
HPLC and UHPLC Methods for Melamine
Reveleris iES Flash System
Isolation and purification of natural products is a challenging, tedious, and lengthy process requiring multiple steps and a large amount of
organic solvent. The use of the Reveleris™ automated flash chromatography instrument and Reveleris™ reversed-phase cartridges can
ease the process.

After 2007 and more recent melamine contamination outbreaks, there is an urgent need for analytical methods that can identify
and quantify melamine in food. Current melamine detection methods involve LC-MS and GC-MS. GC-MS methods require
derivatization, and LC-MS methods generally use gradient conditions that require column clean up and re-equilibration.
Grace has developed MS-compatible LC methods for Melamine using an HILIC media platform that can be applied to both
traditional HPLC as well as UHPLC systems. Melamine was analyzed with a standard HPLC system using a 5µm particle HILIC
phase packed into a 250 x 4.6mm column. The 1.5µm version of this phase was then packed into a high throughput format
conducive to UHPLC and fast LC systems. Both methods deliver excellent linearity and use isocratic elution for fast analysis
without the need for re-equilibration.

Compared to the conventional HPLC method, the UHPLC method is 4 times faster. With the use of 1.5μm particles, optimal linear velocities extend over a
wider range. Therefore, it is possible to maintain efficiency and resolution while running samples at faster flow rates.

Toxicology studies show ingestion of melamine in large quantities may lead to reproductive damage or bladder cancer due to the
formation of bladder/kidney stones. At lower levels, melamine and cyanuric acid are absorbed into the bloodstream. Together,
they concentrate and form melamine cyanurate in the urine-filled renal microtubules. Cystallization blocks and damages the
renal cells that line the tubes, causing the kidneys to malfunction.
