Comparison of Diamond Hydride to C18 HPLC Column
Prasugrel has a tertiary Amine and therefore tails in many Reversed Phase methods and conventional HPLC columns. Figure A shows how a sharp and symmetrical peak can be easily obtained with the Cogent Diamond Hydride Column using an MS-compatible Mobile Phase.
Figure B shows the peak that was obtained using a Reversed Phase gradient (30–60%B over 5 minutes) using the same Mobile Phase solvents and a Type B silica based C18 Column. Here the effects of residual silanols on the Type B silica based column lead to peak tailing.
Column: Cogent Diamond Hydride™, 4 μm, 100 Å
Catalog No.: 70000-7.5P
Dimensions: 4.6 x 75 mm
Mobile Phase:
Post Time: 2 minutes
Flow rate: 1.0 mL / minute
Detection: 254 nm
Injection vol.: 1 μL
Sample Preparation: 0.1 mg / mL Prasugrel in Methanol diluent.
t 0 : 0.9 minutes
Note: Prasugrel is a platelet inhibitor which was approved by the US Food and Drug Administration in 2009 for the reduction of thrombotic cardiovascular events. It is marketed as Effient®.
