石墨炉原子化器中石墨管的温度对于分析物一次连续完全原子化是很重要的。但有一些原子吸收光谱仪的石墨炉却没有高温计,常利用电流表来指示温度,如沈阳仪器厂生产的石墨炉电源在说明书中附一张电流-温度对照表,这在石墨管电阻大体一致的情况下是可用的,但目前一些单位自制石墨管,在更换石墨管时必须注意一些问题。温度取决于加在石墨管上的功率、散热条件及环境温度。如后两个因素一定,温度主要取决于前者,功率愈大、升温愈快。因此,在原子化时,控制加在 The temperature of a graphite tube in a graphite furnace atomizer is important for a continuous, complete atomization of the analyte. However, there are some atomic absorption spectrometer graphite furnace but no pyrometer, often use ammeter to indicate the temperature, such as the Shenyang Instrument Factory graphite furnace power supply in the manual with a current - temperature table, which is generally consistent with the graphite tube resistance The case is available, but some units of self-made graphite tube, the replacement of graphite tube must pay attention to some problems. The temperature depends on the power added to the graphite tube, cooling conditions and ambient temperature. As the latter two factors must be, the temperature depends mainly on the former, the greater the power, the faster warming. Therefore, when atomizing, control is added
