Simple and Fast Quantitation of Nicotinic Acid and Nicotinamide in Human Plasma by Applying Impact™ Protein Precipitation Plate Technology with Gemini® 3 μm C18 HPLC Columns

Impact™ protein precipitation plates with Solvent Shielding Technology™ offer a rapid and convenient way to remove proteins from plasma and tissue homogenate samples prior to analysis.The Solvent Shielding Technology design will withhold organic solvents above the filter membranes for up to 25 minutes, allowing for direct in-well precipitation upon sample addition. The precipitate is then filtered out via vacuum, centrifuge or positive pressure resulting in a clean, protein depleted extract.
