Abstract
The low-power electricglow discharge in helium can excite efftctively the characteristic emission lines of sodium and potassium. The helium-glow photometer used to generate the glow and measure the light is a relatively simple apparatus; it can be used to analyze samples containing 10(-14) mole or more of sodium and potassium. Overall precision of the apparatus and method is 5 percent or better.
摘要
氦气中的低功率辉光放电能够有效地激发钠和钾的特征发射线。用于产生辉光并测量光的氦辉光光度计是一种相对简单的仪器；它可用于分析含有10⁻¹⁴摩尔或更多钠和钾的样品。该仪器和方法的总体精度为5%或更高。
