A high-sensitivity spectrometer for emission spectral analysis based on a modified two-jet DPG-50M plasmatron and high-resolution spectral equipment using a multichannel spectrum recorder is proposed. The spectrometer was tested by measuring gold concentrations by classical and scintillation spectral methods. The possibility of significantly reducing the sensitivity limits of spectral analysis in the determination of small gold contents by the scintillation method is demonstrated.

升级版发射光谱仪，用于金的闪烁光谱分析

提出了一种基于改进的双射流DPG-50M等离子加速器和使用多通道频谱记录仪的高分辨率光谱设备的发射光谱分析高灵敏度光谱仪。通过经典和闪烁光谱法测量金浓度来测试光谱仪。证明了通过闪烁法显着降低光谱分析灵敏度极限的可能性，可用于测定少量金。
