New Ionic MALDI

Ionic matrix substances are a new class of matrices composed of organic acids (classical matrices, others turned out to be unsuitable) and organic bases. Ionic matrices, especially the low-melting ones, provide several striking advantage. These matrix systems have excellent solubilizing properties compared to other commonly used matrices. They allow homogeneous sample preparation with a thin ionic liquid layer having negligible vapour pressure. This leads to a facilitated qualitative and quantitative measurements compared to classical matrices.

It has been shown, that ionic matrices yield a very homogeneous drop, so that performance of a single shot is much more reproducible and search for a "hot spot" is not required.
We have produced ionic matrices with highest purity. The use of these highly purified matrices results in high signal-to-noise ratios.
