Hamamatsu Photonics has expanded its lineup of ionization-assisting substrates now selectable from a total of 9 types according to samples. Product sales will start on October 20, 2020.




Here at Hamamatsu Photonics we have added 4 new products to our “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 currently available MALDI-TOF MS that works by a combination of MALDI(*1) and TOF MS(*2) techniques. Salesof these new products will begin on October 20 (Tue), 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.

*1: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.

*2: 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.
