An optimum generation efficiency of 60 ± 2 % was achieved in 50 % formic acid at pH 2.5 with an irradiation time of 250 s by use of a 17 W low pressure mercury grid lamp. Compared to conventional solution nebulization, sensitivity and limit of detection were improved 80-and 100-fold, respectively, yielding 1620 cps per ng/ml and 0.025 ng/ml at the 238.204 nm Fe II emission line. A precision of 0.75 % RSD was achieved at

Integration of hydride generation and photochemical vapor generation for multi-element analysis of traditional Chinese medicine by ICP-OES

“…It has been proven that the PVG efficiency of several elements, such as Ni and Fe, would be remarkably depressed when inorganic acids such as HNO 3 and HCl were involved [13][14][15]. As reported previously, the best PVG efficiency of Co and Ni can be obtained in the medium of formic acid [14,15].…”

“…ACCEPTED MANUSCRIPT 13 the volatile species were introduced to the ICP-OES for simultaneous muli-element analysis. This is the first attempt of combination of two different CVG technologies for sample introduction to ICP-OES, and higher sample introdution efficiency, less matrix and spectral interferences, higher selectivity and muti-element determination were achieved for real samples.…”

Application of chemical vapor generation in ICP-MS: A review

“…Guo et al [41] first introduced PVG in 2003, and applications of this new sample introduction quickly expanded [42,43]. A wide range of elements can be photochemically derivatized to volatile species, such as Hg [44,45], Ni [46,47], Se [43], Co [48,49], Fe [50], and I [51,52]. A typical schematic of PVG system is shown in Figure 2.…”

Identification of volatile iron species generated by UV photolysis

“…To date, analytical applications of PVG have been undertaken for only a few analytes, in both continuous flow and batch systems, including Fe in biological samples and water [5,6], iodine in milk powder, biological samples and soil [7], and Hg in biological samples [8,9], as well as water [10] and wine or liquor [11]. Clearly, more effort needs to be expended in pursuing applications but the interest at this time lies predominantly in further expansion of the suite of elements amenable to PVG.…”
