Title: Time Division Multiplexing (TDM) and Wavelength Division Multiplexing (WDM) sensor arrays
Inventor: DOMINO TAVERNER
IPC: G01D5/353
Filed: 2015-06-03
Abstract: Methods and apparatus for interrogating sets of optical elements having characteristic wavelengths spanning a sweep range while avoiding overlapping reflections from the different sets when performing a wavelength sweep are provided. One example method generally includes introducing a pulse of light, by an optical source, into an optical waveguide to interrogate at least first and second sets of optical elements, wherein the optical elements within each set have different characteristic wavelengths and wherein the first and second sets are separated in time such that a first time window over which light is reflected from the optical elements in the first set and reaches a receiver does not overlap with a second time window over which light is reflected from the optical elements in the second set and reaches the receiver; and processing the reflected light to determine one or more parameters corresponding to the optical elements.

Title: Optimised targeted analysis
Inventor: MARTIN RAYMOND GREEN
IPC: H01J49/00
Filed: 2017-04-12
Abstract: A method of mass spectrometry comprises mass analysing precursor ions, and/or product ions derived therefrom, during sequential acquisition periods wherein the value of an operational parameter of the spectrometer is varied. The spectral data obtained in each acquisition period is stored with its respective value of the operational parameter. The stored spectral data is interrogated to determine which of the spectral data meets a predetermined criterion (e.g. an intensity or signal to noise ratio) in order to determine a target operational parameter value. The precursor or product ions are mass analysed again using the target operational parameter value. Temporally separated precursor ions may be provided using chromatography or ion mobility separation, which may be fragmented or reacted to produce the product ions. The operational parameter may be accelerating potential, collision energy, ionisation efficiency, ionisation energy, parameter of an ion mobility filter, setting of an electrostatic or RF device, ion attenuation level, electron multiplier setting, mass filter resolution or ion trapping time.
