High ionisation energy:
The high ionisation energy of helium (24.6 eV) makes it a potential gas to be used in plasma source.
The nitrogen gas is generally not used as a plasma gas in plasma based atomic emission spectrometry because the excited nitrogen emits a complex band spectrum that can cause undesirable spectral interference.
Polychromator is a type of simultaneous spectrometer. It has a fixed diffraction grating monochromator and multiple 'exit slits' with associated photomultipliers. Every of the photomultiplier is optimized to detect a specified wavelength corresponding to an element of interest. The emission radiation from the source is dispersed by the grating and sent through different exit slits to be detected by appropriate photomultiplier tube.

at what temperature centigrade will the volume of a gas at 0 degrees Celsius double itself pressure remaining constant
Sedimentation: The process of allowing w ater to stand undisturbed in big tanks for some time in order to facilitate the settling down of the course suspended particles due to th
Merits of atomic fluorescence spectrometry technique: The merit of the AFS methods lies within the greater sensitivity achievable because of low background and interference.
1-methylcyclohexene Because 1-methylcyclohexene has dissimilar numbers of alkyl branches at the carbons of its double bond, it gives dissimilar products in the two reactions.
