A system as claimed in any preceding claim, comprising a memory for storing a spectra or data associated with a known gas, which spectra or data is used by the processor to identify the gas.ġ1. A system as claimed in any preceding claim, wherein the electrodes (40) are excited by inductive coupling.ġ0. A system as claimed in any preceding claim, wherein the electrodes (40) are separated by a spacer (42).ĩ. A system as claimed in any preceding claim, wherein the electrodes (40) are spaced apart by an amount in the range of substantially 40 to 200µm, preferable 50 to 100µm.Ĩ.
A system as claimed in any preceding claim, wherein at least one of the substrates (36, 38) is wholly or substantially formed from glass.ħ. A system as claimed in any preceding claim, wherein at least one of the substrates (36, 38) is formed of material transparent to the relevant spectrometer wavelengths.Ħ. A system as claimed in any preceding claim, wherein the electrode arrays (40) are located on internal cell-surfaces of the substrates (36, 38).ĥ. A system as claimed in claim 1 or claim 2, wherein the electrodes (40) on each array are linear.Ĥ. A system as claimed in claim 1, in which at least one of the substrates (36, 38) is operable to act as a waveguide for light emitted by the plasma.ģ. The cell comprising opposing first and second substrates (36, 38) defining a region between them, the first substrate (36) has a first array of electrodes (40) adjacent the region and the second substrate (38) has a second array of electrodes (40) adjacent the region, which electrodes together define an array of individually addressable elements, individually operable to form a plasma in the region.Ģ. A system for identifying gases, the system comprising means for forming a plasma using the gas to be identified (34), a sensor (66) for sensing light emitted from the plasma and a processor adapted to use information on the sensed light to identify the gas, wherein the means for forming a plasma comprises electrodes which are provided as part of a cell, Updated MaNow supports saving search queries from PubMed and Google Scholar to My Folders!
