Ultra-Pure MALDI Matrices

One of the most important aspects of our ultra-pure MALDI matrix substances is their ability to dissolve rapidly and completely; a brief vortex mixing is typically sufficient.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
