Sample target used in mass spectrometry, method for producing the same, and mass spectrometer using the sample target |
摘要 |
In one embodiment of the present invention, a sample target that allows ionization of a substance whose molecular weight is so high as to exceed 10000 in mass spectrometry that ionizes a sample without using matrix, a method for producing the same and a mass spectrometer using the sample target. The sample target includes a sample support surface including a large number of fine pores on its face receiving irradiated laser light. Each of the fine pores has a diameter of 30 nm or more and 5 mum or less. The number indicative of pore depth/(pore cycle-pore diameter) of each of the fine pores is 2 or more and 50 or less. The face of the sample support surface is coated with metal or semiconductor.
