Zirconia analyzer is used to measure

Which device is used to isolate the radiation of the desired wavelength from wavelength of the continuous spectra?

A spectrophotometer is used to measure the concentration of a molecule in a solution based on Beer's law using cuvette of path length 10mm and detectable absorbance of 0.01. The molar absorptivity of the solution is $10^4$ l/mol-m. The minimum concentration of the solution that can be detected is

An experiment was carried out twice using magnetic deflection type mass-spectrometer to estimate a certain molecule present in the compound under test. In the first test, the sample was excited and the potential difference between the accelerating plate was kept at 1000 V and in the second case, the potential difference was at 10000 V. Determine the ratio of the radius of curvature of the circular path travelled by the ions when they pass through the magnetic field oriented right angle to their motion in the test to that of the second

In a spectrophotometer, the monochromator must be able to resolve two wavelengths 599.0nm and 600.1nm. The required resolution is
