Desorption electro-flow focusing ionization (DEFFI) mass spectrometry was used to image chemical distributions of endogenous, e.g., fatty acids, and trace exogenous compounds, e.g., explosives, narcotics and lotions, in deposited and lifted artificial fingerprints, directly from forensic lift tape. An artificial fingerprint mold and synthetic fingerprint material were incorporated for the controlled deposition of material for technique demonstration and evaluation.
解吸电流聚焦电离（DEFFI）质谱法用于直接从法医提取胶带成像沉积和提起的人工指纹中内源性化学物质（如脂肪酸）以及痕量外源性化合物（如爆炸物、麻醉品和洗剂）的化学分布。引入了人工指纹模具和合成指纹材料，用于控制材料的沉积，以进行技术演示和评估。
