    • The invention relates to analytical chemistry. In the analyser, mercury placed in a spectral lamp is enriched with a mercury isotope having an even neutron number, wherein said isotope constitutes not less than 50% of the total mercury content in the spectral lamp. Moreover, the discharge cavity of the spectral lamp is connected to a ballast cavity, the volume of which is greater than the discharge cavity volume, and electrical discharge generating means, the discharge cavity and the ballast cavity are designed in such a way that the discharge generated in the discharge cavity does not penetrates into the ballast cavity. A buffer gas in the spectral lamp contains a noble gas in a quantity equal to or greater than 50%, the charge of the atomic core of said gas being not less than 36. Said invention makes it possible to lower the detection level of mercury in a carrier gas and to reduce a drift.
    • 本发明涉及分析化学。 在分析仪中,放置在光谱灯中的汞富含具有均匀中子数的汞同位素,其中所述同位素构成不小于光谱灯中总汞含量的50%。 此外,光谱灯的放电腔连接到其体积大于排出腔体积的压载腔,并且放电产生装置,排放腔和镇流器腔被设计成使得放电 在放电腔中产生的不会渗透到镇流器腔中。 光谱灯中的缓冲气体含有等于或大于50%的惰性气体,所述气体的原子核的电荷不小于36.所述发明使得可以降低汞的检测水平 载气并减少漂移。
