Certain embodiments described herein are directed to methods and systems of detecting two or more analytes present in a single system such as a nanoparticle or nanostructure. In some examples, the methods and systems can estimate data gaps and fit intensity curves to obtained detection values so the amount of the two or more analytes present in the single system can be quantified.

Methods and systems for quantifying two or more analytes using mass spectrometry

Devices, systems and methods including a spray chamber are described. In certain examples, the spray chamber may be configured with an outer chamber configured to provide tangential gas flows. In other instances, an inner tube can be positioned within the outer chamber and may comprise a plurality of microchannels. In some examples, the outer chamber may comprise dual gas inlet ports. In some instances, the spray chamber may be configured to provide tangential gas flow and laminar gas flows to prevent droplet formation on surfaces of the spray chamber. Optical emission devices, optical absorption devices and mass spectrometers using the spray chamber are also described.

Spray chambers and methods of using them

Certain configurations of devices are described herein that include a DC multipole that is effective to doubly bend the ions in an entering particle beam. In some instances, the devices include a first multipole configured to provide a DC electric field effective to direct first ions of an entering particle beam along a first internal trajectory at an angle different from the entry trajectory of the particle beam. The first multipole may also be configured to direct the ions in the first multipole along a second internal trajectory that is different than the angle of the first internal trajectory of the particle beam.

Double bend ion guides and devices using them

Methods and systems of identifying two or more elements in a single individual particle are described. In some examples, an optical emission from each of an ionized first element and an ionized second element can simultaneously be detected to identify at least a first element in a particle from a plurality of particles using the optical emission from the ionized first element, and to identify at least a second element in the particle from the plurality of particles using the optical emission from the second ionized element. The identified first element and the identified second element can be used to identify a source of the particle from a plurality of particles.

Single particle analysis using optical detection

The present disclosure provides methods and systems for automated analysis of spectrometry data corresponding to particles of a sample, such as large data sets obtained during single particle mode analysis of an inductively coupled plasma mass spectrometer (SP-ICP-MS). Techniques are presented herein that provide appropriate smoothing for rapid data processing without an accompanying reduction (or with an acceptably negligible reduction) in accuracy and/or precision.

Systems and methods for automated analysis of output in single particle inductively coupled plasma mass spectrometry and similar data sets

The present disclosure provides methods and systems for automated tuning of multimode inductively coupled plasma mass spectrometers (ICP-MS). In certain embodiments, a 'single click' optimization method is provided for a multi-mode ICP-MS system that automates tuning of the system in one or more modes selected from among the multiple modes, e.g., a vented cell mode, a reaction cell mode (e.g., dynamic reaction cell mode), and a collision cell mode (e.g., kinetic energy discrimination mode). Workflows and computational routines, including a dynamic range optimization technique, are presented that provide faster, more efficient, and more accurate tuning.

Systems and methods for automated optimization of a multi-mode inductively coupled plasma mass spectrometer

Certain embodiments described herein are directed to systems including a cell downstream of a mass analyzer. In some instances, the cell is configured as a reaction cell, a collision cell or a reaction/collision cell. The system can be used to suppress unwanted ions and/or remove interfering ions from a stream comprising a plurality of ions.
