Blank problems in the detection of gold by electrothermal atomisation and laser-induced fluorescence

Atomic Spectrometry Update. Advances in atomic emission, absorption, and fluorescence spectrometry, and related techniques

“…For the determination of Au, double resonance LEAF with ETA gave LODs at the low fg level. 567 As a result of such high sensitivity there was a significant problem of blank signals which had to be addressed. A variety of furnace coatings and linings were investigated for the determination of ultratrace levels of Tl by ETA-LEAFS.…”
