Description

Analysis Note

9:1 mixture of DHB and 2-hydroxy-5-methoxybenzoic acid

General description

The “super-DHB” matrix consists of a 9:1 (w/w) mixture of 2,5-DHB and 2-hydroxy-5-methoxybenzoic acid, respectively, since this ratio was found to be the most effective. The beneficial effect of the 2-hydroxy- 5-methoxybenzoic acid additive is attributed to a disorder in the 2,5-DHB crystal lattice resulting in enhanced ion desorption (i.e. ‘softer’ desorption) and reduced internal energy, which in turn results in reduced metastable fragmentation. An increase in sensitivity of up to 2 to 3-fold has been reported for a standard dextran mixture with concomitant enhanced resolution attributed to reduced metastable ion formation. The super-DHB matrix has also been reported to generate enhanced signals from tryptic glycopeptides. The use of super-DHB matrix is reported to reduce the presence of matrix background ions and result in glycan signals exhibiting better signal to noise ratios and higher resolution in the mass spectrum.
