Beschreibung

Allgemeine Beschreibung

MALDI-MS analyzes require highest purity matrices and reagents, as organic or trace metal contamination causes adverse effects during crystallization, ionization or measurement. Therefore, our portfolio of MALDI matrices and reagents such as 2′,4′,6′-Trihydroxyacetophenone monohydrate are designed to fulfill the demanding requirements of today′s challenging applications.

Anwendung

Verwendet in der MALDI-Analyse von sauren Glycanen und Glycopeptiden im Negativ-Ionen-Modus. Niedrigere Nachweisgrenze als 6-Aza-2-thiothimidin.

2′,4′,6′-Trihydroxyacetophenone monohydrate has been used as a matrix for oligosaccharide and glycopeptide analysis using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI/TOF).
