The sensitive determination of Ag, Pb and Tl as well as reduction of spectral interferences in a hanging drop cathode atmospheric pressure glow discharge excitation microsource equipped with a Dove prism system

Abstract

The application of hanging drop cathode atmospheric pressure glow discharge (HDC-APGD) coupled with a Dove prism (DP) as an efficient excitation microsource for optical emission spectrometry (OES) was evaluated in...

Atomic spectrometry update: review of advances in atomic spectrometry and related techniques

“…Following dissolution using HNO 3 and aqua regia, aliquots of these samples were puried using AG1-X8 cation exchange. The results indicated that there was little bias in d 56 Fe between the puried and unpuried samples. This allowed for a simplied and efficient procedure for Fe isotope studies centred on Fe-dominated minerals.…”

“…Swiderski at al. 56 described the use of a hanging drop cathode (HDC) APGD coupled with a Dove prism as an excitation microsource for OES. The effect of the addition of low molecular weight organic compounds on the intensity of the analytical lines of Ag, Ca, Cd, Hg, Mg, Mn, Pb and Tl were evaluated.…”

Atomic spectrometry update – a review of advances in environmental analysis

“…Swiderski et al 163 investigated hanging-drop-cathode APGD as an excitation source for AES. Incorporation of a Dove prism, to rotate the discharge image by 90°, and addition of 8% (m/m) formic acid together enhanced the intensity of analyte lines relative to background.…”

“…In a method described in more detail in Section 4.3.1 of this ASU, soil samples were introduced 136 into the HG-DBD-AES system as a slurry. Swiderski et al 163 investigated hanging-drop-cathode APGD as an excitation source for AES. Incorporation of a Dove prism, to rotate the discharge image by 90°, and addition of 8% (m/m) formic acid together enhanced the intensity of analyte lines relative to background.…”
