Hydride generation – in-atomizer collection of Pb in quartz tube atomizers for atomic absorption spectrometry – a 212Pb radiotracer study

A sapphire tube atomizer for on-line atomization and in situ collection of bismuthine for atomic absorption spectrometry

“…In addition, it has been observed that oxides formed from hydrides of Sb, Bi, Se, As and Pb are trapped in the quartz tube atomizers. 8,[20][21][22][29][30][31] An analogous behavior was recently observed in the case of volatile species of Ag. 6 Generally, sensitivity in the EHQTA increases with decreasing total gas ow rate.…”

Ultratrace determination of arsenic by hydride generation atomic absorption spectrometry with preconcentration on gold nanoparticles

“…Our original intention was to optimize hydride trapping and subsequent analyte volatilization employing the bare quartz surface. These efforts were successful in the case of Sb, [31][32][33] Bi, 31,32,34 Pb 35,36 and Sn. 37 As a consequence, 100% preconcentration efficiency was reached for all these four analytes under optimized conditions employing a preconcentration at the non-modied quartz surface in an integrated trap-and-atomizer device.…”

Atomic spectrometry updates: Review of advances in atomic spectrometry and related techniques

“…This was eliminated by increasing the K 3 [Mn(CN) 6 ] concentration to 1%, but does not bode well for the analysis of real samples. Kratzer et al 44 used radioactive 212 Pb to investigate the HG and trapping efficiency of plumbane using a similar method which also utilised NaBH 4 /K 3 [Fe(CN) 6 ] as an enhancing reagent. They prepared the 212 Pb tracer by precipitation of PbS from Th(NO 3 ) 4 with subsequent purication by ion exchange separation to yield 212 PbCl 2 .…”
