Hamamatsu Photonics expands its lineup of ionization-assisting substrates

Hamamatsu Photonics have added four new products to its “DIUTHAME” (Desorption Ionization Using Through Hole Alumina Membrane) series ionization-assisting substrates, that drastically cut the pretreatment time needed to ionize samples by laser in mass spectrometry.

These new products include a miniature type, ideal for mass spectrometry imaging of small samples and a glass-slide size type for mass spectrum measurement that can be directly set into spectrometer holders. Our expanded lineup for the DIUTHAME series now includes a total of 9 types, allowing users to select the DIUTHAME that best matches the size of samples to measure with a MALDI-TOF MS that works by a combination of MALDI and TOF MS techniques. Sales of these new products will begin on October 20, 2020, mainly for researchers at domestic and overseas business organizations and universities who use MALDI-TOF MS in various fields such as drug discovery, biochemistry, food industry, and cosmetics.

• MALDI or matrix-assisted laser desorption/ionization is a major ionization technique used in mass spectrometry, in which a sample is pre-mixed with low-molecular-weight organic compound (called a matrix) and ionized by laser irradiation.
• TOF MS or time-of-flight mass spectrometry is a technique that determines the mass of atoms and molecules by measuring the time-of-flight of the ions.
