    • An object of the present invention is to provide a sample substrate for laser desorption ionization mass spectrometry for LDI-MS which substrate enables mass spectrometric analysis of a sample correctly at high sensitivity without generating interference peaks upon irradiation of the sample to laser light and uniform application of the sample onto a base. Another object of the invention is to provide a mass spectrometer (device) employing the sample substrate.In the sample substrate for laser desorption ionization mass spectrometry, the sample substrate is formed of a base and carbon nanowalls having wall surfaces onto which a sample to undergo mass spectrometry is applied, wherein the carbon nanowalls are formed on the base so as to stand on the base. The surfaces of carbon nanowalls serve as an ionization medium and hydrophilized. By use of the sample substrate, mass spectrometry of a sample having a wide range (high to low) molecular weight can be reliably performed at high precision and sensitivity.
    • 本发明的目的是提供一种用于LDI-MS的激光解吸电离质谱的样品基片,该基片能够以高灵敏度正确地对样品进行质谱分析,而不会在将样品照射到激光上并产生均匀的应用时产生干涉峰 的样品到基底上。 本发明的另一个目的是提供一种采用样品基质的质谱仪(装置)。 在用于激光解吸电离质谱的样品衬底中,样品衬底由具有壁表面的基底和碳纳米壁形成,其上应用要进行质谱的样品,其中碳纳米壁形成在基底上以便立在 的基地。 碳纳米壁的表面用作电离介质并亲水化。 通过使用样品基板,可以以高精度和灵敏度可靠地进行具有宽范围(高低分子量)的样品的质谱分析。
