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) In an atomic absorption spectrophotometer, if the lamp does not emit light, then ( ). A. Reverse the positive and negative poles for more than half an hour. B. Use a higher voltage (above 600V) to initiate discharge. C. Connect a resistor of 2–10 kOhms in series. D. Discharge at 50mA. Correct answer: B. Reply with your answer in the comments; you will receive +2 wealth points for participating in the quiz. An additional +3–8 wealth points will be given if all answers are correct. Extra rewards will be offered if the questions or answers are analyzed and explained in detail, or if detailed calculation processes are provided. If your answer is correct and your analysis/explanation is thorough, it will be marked as the best reply (or the best assistance). Feel free to answer the questions.
