Intellectual Olympiad in Physical-Chemical Analysis Methods Laboratory - 2026 ongoing

Subject: Physical-Chemical Analysis Methods Laboratory
Level: XI
Category: student
Quiz questions: in English
Example question: A UV–visible method is applied to a strongly absorbing sample that exhibits inner-filter effects. Which correction is most appropriate when the absorbance at the excitation and emission wavelengths is known? Increase the cuvette path length to amplify the measured fluorescence, Replace the fluorophore with a nonabsorbing reference compound, Correct the observed fluorescence for attenuation of excitation and emitted radiation, Add a chemical oxidant to eliminate all absorption bands
