Make sure each step is passed before proceeding to the next one. 这个程序用于检查所有重要的系统和方法性能参数以及帮助确定问题的来源。 在进行下一步之前确保每一步都已经通过。 0. Colorimeter check (if needed for troubleshooting: not part of everyday start-up) 比色计检查（如果需要做故障检查：不是每天启动所必须的） 0.1 Switch on all colorimeters and start the chart. 打开所有比色计，开始Chart 0.2 Fill the flowcell with water, e.g. by disconnecting the tubing outside the colorimeter inlet and filling with a syringe. 用水注满比色池，例如，断开进出比色计的管路，用注射器将水注入比色池 0.3 Open the colorimeter control window in AACE and set the lamp power manually to achieve a reference energy of 50 - 80% or the highest available. The highest achievable energy depends on the wavelength and light source. Write down the sample and reference energy and the lamp power setting. Calculate the flowcell transmission efficiency in %. It should be more than 20% for a 10 x 1mm flowcell. 打开AACE软件中比色计的控制窗口，手动设置灯能量到参比能量的50-80%或者可用的最大值。最高可达到的能量依赖于波长和光源。记下样品和参比能量以及灯能量设定。计算比色池透光率百分比，对于10 ( 1mm比色池来说应该高于20% 0.4 Set the Gain to 100 and do Autobase. After a warm-up period if needed (e.g. in a laboratory with low or variable temperature) note the chart reading in % and the time on the chart. After 30 minutes the baseline should be noise-free and the drift should be less than 1% per hour. 将Gain设定到100并且Autobase。在一段准备周期（如果必要的话，例如实验室中低的或者变化的温度）后，记录Chart的读数%和时间。30分钟后基线应该没有噪音并且漂移应该小于1%. 1. Hydraulic Check 水力学检查 1.1 Pump water + wetting agent through reagent lines. (Exceptions: (i) sampler wash solution; this does not contain surfactant, and is a special solution for some seawater, soil and digested sample methods. (ii) UV digestor methods: surfactan
