摘要
In various embodiments, a device may generally comprise a remote ablation chamber comprising an inlet and an outlet, a laser to deposit energy into a sample in the chamber to ablate the sample and generate ablation products in the chamber, a transport device in fluid communication with the outlet, an ionization source to ionize the ablation products to produce ions, and a mass spectrometer having an ion transfer inlet to capture the ions. The ablation products or the ions may be transported in a fluid stream from the ablation chamber through the transport device. The distance from the outlet of the ablation chamber to the ion transfer inlet may be from 1 cm to 10 m. The device may comprise a rLAESI-MS device as generally described herein. Methods of making and using the same are also described.
