摘要： A flash heater element (200) includes a first surface (202) having a central region (234) and an electrical flow path (220) disposed on the first surface. The electrical flow path includes a central portion (240) disposed at least partially within the central region and a peripheral portion (238) disposed peripherally outwardly from the central region. A width (244) of the electrical flow path is greater within at least a portion of the central portion than the width (246) of the electrical flow path within the peripheral portion. Also disclosed is a detection system (100) comprising a housing (110), a desorber (112), a heater (130), flash heater element (200) and a detector (114).
