==TIME OF FLIGHT MASS ANALYSER AND METHOD OF TIME OF FLIGHT MASS SPECTROMETRY - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240055250 titled 'TIME OF FLIGHT MASS ANALYSER AND METHOD OF TIME OF FLIGHT MASS SPECTROMETRY

==Simplified Explanation==

The abstract describes a time of flight (TOF) mass analyzer that includes an ion source, a detector, an electrode, and a resistive divider with first and second resistors. The ion source and detector create an ion flight path, while the electrode receives an output voltage and is positioned along the ion flight path. Thermal expansion causes a mass shift/Kelvin of detected ions. The resistive divider is thermally connected to the TOF mass analyzer, receiving an input voltage and outputting an output voltage to the electrode. The resistors have temperature coefficients that adjust the output voltage to compensate for the mass shift/Kelvin of detected ions.

* The TOF mass analyzer includes an ion source, detector, electrode, and resistive divider.
* Thermal expansion causes a mass shift/Kelvin of detected ions.
* The resistive divider adjusts the output voltage to compensate for the mass shift/Kelvin.
* The resistors have temperature coefficients that enable this compensation.

- Improved consistency in ion detection


==Original Abstract Submitted==

a time of flight (tof) mass analyser comprises an ion source, a detector, an electrode, and a resistive divider comprising first and second resistors. the ion source and the detector define an ion flight path from the ion source to the detector. the electrode is arranged along the ion flight path and receives an output voltage. thermal expansion produces a first mass shift/kelvin of detected ions. the resistive divider is thermally coupled to the tof mass analyser to receive an input voltage and output an output voltage to the electrode. the first and second resistors have respective first and second temperature coefficients that provide a voltage shift/kelvin to the output voltage to the electrode producing a second mass shift/kelvin of detected ions, compensating for the first mass shift/kelvin.
