濱松多孔氧化鋁制作的輔助離子化基板DIUTHAME（Desorption Ionization Using Through Hole Alumina MEmbrane），可大幅縮減質譜成像分析時待測樣品進行離子化所需的前期處理的時間。
只要將本產品放置在待測樣品上，就能完成質量分析的前期處理，與目前主要的離子化方法之一基質輔助激光解析電離（Matrix-Assisted Laser Desorption/Ionization、下面簡稱MALDI）方法相比，它將前期處理時間縮短到十分之一。因此可以用在市場上已有的MALDI-TOF-MS設備，主要面向目前正在使用MALDI-TOF-MS設備的制藥、工業領域的國內外企業以及大學研究人員。
A13331-18-2通道的有效面積為Φ18mm。（大面積成像專用）
