It is intended to provide a novel method by which an organic molecule such as a protein or an endocrine disruptor can be analyzed at a high sensitivity. A secondary ion mass spectrometry method with the use of a heavy ion beam as a primary ion beam, which can achieve a high sensitivity, is usable in detecting a biologically-relevant substance at, for example, the subattomole level. Thus, it becomes possible to favorably image a biologically-relevant sample. |
