Microsecond Pulsed Glow Discharge (μs-PGD) was applied to commercially available spectrometers specified for OES elemental analysis with Grimm type sources, in order to have a look at the benefits which PGD can bring for practical bulk analysis. Intensities of more than 70 spectral lines of different elements together with background and noises were compared between μs-PGD and continuous Glow Discharge (GD) using CCD and PMT detectors. In comparison to continuous GD, the detection limits with PGD were 1.5–14 times lower for different spectral lines. The reasons for such a moderate improvement are discussed.

微秒脉冲辉光放电在现代市售光发射光谱仪中进行块状元素分析的应用†

将微秒脉冲辉光放电（μs-PGD）应用于指定用于使用Grimm型离子源进行OES元素分析的市售光谱仪，以了解PGD可以为实际批量分析带来的好处。使用CCD和PMT检测器比较了μs-PGD和连续辉光放电（GD）之间不同元素的70条光谱线的强度以及背景和噪声。与连续GD相比，PGD的检测限对于不同光谱线要低1.5–14倍。讨论了这种适度改进的原因。
