  • User exchangeable ablation cell interface to alter LA-ICP-MS peak widths
    Patent number: 11837454
    Abstract: In an embodiment, a laser ablation system can include a laser ablation cell and at least a pair of particle-collection-to-transport-tubing interfaces. The laser ablation cell can be configured for ablating a sample or another material, and the laser ablation cell can include a laser unit. The at least a pair of particle-collection-to-transport-tubing interfaces can be configured to gather an ablated sample and direct the ablated sample to an analysis unit. A selected particle-collection-to-transport-tubing interface can be received by the laser ablation cell directly above the laser unit. The at least a pair of particle-collection-to-transport-tubing interfaces can be configured to be interchangeable with one another.

  • Adjustable sample floor for ultrafast signal washout
    Patent number: 11122672
    Abstract: Systems and methods for an adjustable sample floor for ultrafast signal washout are disclosed. In an embodiment. A target support configured to adjustably support a target within a sample chamber may include: a support frame that may configured to be inserted into the sample chamber, a support platform that may be disposed within the support frame, and a platform adjustment system that may be coupled to the support frame and the support platform. The platform adjustment system may be configured to adjust at least one of: a position and an orientation of the support platform relative to the support frame when the support frame is inserted into the sample chamber.
