To increase the popularity of the chemical analysis section, a \"One Question per Day\" campaign has been launched; this aims to foster active technical exchanges while also providing financial rewards to users. 【Daily Question】 (Single-choice question) To analyze atomic absorption spectra in the spectral range of 165–360 nm, which light source should be used? A Tungsten lamp B Nernst lamp C Hollow cathode lamp D Deuterium lamp. Correct answer: C. Post your answer in the replies; participating in the quiz earns you +2 wealth points. Getting all answers correct grants an additional +3 to +8 wealth points. Those who provide thorough analyses and explanations for the questions or answers (or include detailed calculation processes) will receive extra wealth points as a reward. If your answer is correct and your analysis/explanation is accurate, it will be marked as the best reply (or the best assistance). Feel free to answer the questions. Note: We will close this post after 24 hours, and at that time we will announce the best reply (the best assistance), as well as the answer and explanation.
