“…Externally heated quartz tube atomizers (QTA) including their advanced designs, such as multiple microflame quartz tube atomizer (MMQTA), are the most common hydride atomizers in AAS characterized by high sensitivity 2,[15][16][17] . Addition of air or oxygen to MMQTA through the outer (auxiliary) gas channel increases sensitivity in case of As, 18,19 Sn, 20,21 Se, 18,22,23 and Te 23 determination benefiting thus from MMQTA construction. The sensitivity reached in QTA/MMQTA is quite comparable among seven hydride forming elements including As, Se, Sb, Bi, Te, Pb and Sn.…”

“…It is comparable with the sensitivity reached in QTA/MMQTA for some analytes such as As, 19 Se, 22,23 Sb, 28 and Te 23, 29 while being significantly lower in DBD for the others including Bi 23, 30 and especially Pb 23,31 and Sn. 20 Apart from QTA and DBD atomizers the hydride forming elements can also be atomized in the atomizers based on diffusion flame (DF) or graphite tube (GT). 2,15 DF is commonly used in AFS rather than AAS since its short optical path is responsible for low sensitivity in AAS leading to 50 times lower signals when compared to QTA or MMQTA.…”

Atomization of three volatile germanium species including germanium hydride (GeH4) and its two methyl-substituted analogues -monomethyl germanium hydride (CH3GeH3) and dimethyl germanium hydride ((CH3)2GeH2) for their detection by atomic absorption spectrometry after hydride generation was comprehensively investigated. Three types of hydride atomizers based on diffusion flame (DF), multiple microflame quartz tube atomizer (MMQTA) and dielectric barrier discharge (DBD) were optimized for atomization of Ge species. In MMQTA, the supply of air and the use of gas phase dryer are the crucial parameters affecting the sensitivity. The presence of the dryer is essential also for DBD atomizer. Sensitivity was quantified under optimized conditions reaching around 2 ms ng -1 Ge in DF and 3 ms ng -1 Ge in MMQTA atomizers, respectively. The highest sensitivity of 10 ms ng -1 Ge was observed in DBD. When compared to other hydride forming elements the sensitivity observed for Ge species is two orders of magnitude worse in MMQTA, 10-50 times lower in DBD and 5 times worse in DF. In given atomizer type, the sensitivity is comparable for all three Ge species indicating the same atomization efficiency. The fraction of Ge deposited in the DBD and MMQTA atomizers, respectively, after atomization of GeH4 was quantified to 80%. Fast decay of free Ge atoms and their deposition at the inner walls of the atomizer might explain low sensitivity observed for Ge determination by atomic absorption spectrometry. Effect of L-Cysteine (L-Cys) addition to liquid standards on response of Ge species was also investigated.

“…Moreover, some heavy metals (As, for instance) has been classified as mutagenic and carcinogenic leading to serious diseases 15 . For these reasons, several techniques have been continually developed for the determination of heavy metals such as atomic absorption spectrometry (AAS) 16,17 , inductively coupled plasma optical emission spectrometry (ICP-OES) 18 , and inductively coupled plasma mass spectrometry (ICP-MS) 19 . However, limitations such as their bulky instruments, high-cost and non-portability are a bottleneck which still requires a major development presuming that it will be further used for on-field analysis.…”

This dissertation focused on the development of portable electrochemical sensors using the paper-based analytical device (ePAD) for the determination of the important compounds/biomarkers in various applications. Considering the target applications, this dissertation can be divided into three main parts including food safety application, environmental analysis and clinical application, respectively. In the first part, two sub-sections relating to the detection of heavy metals contaminated in food will be discussed. For the first sub-section, an ePAD coupled with a boron-doped diamond electrode was developed for the determination of total arsenic. The device was performed using the origami paper device for the preparation of gold nanoparticle-modified boron-doped diamond electrodes and the measurement of arsenic (III) using anodic stripping voltammetry on a single device. For the second sub-section, an ePAD coupled with a portable potentiostat was demonstrated for the simultaneous determination of tin and lead using a bismuth nanoparticle-modified screen-printed graphene electrode as working electrode. In the second part, an ePAD was engineered for NOx gas determination as a model for environmental analysis. The functionality of the developed platform was enhanced by integrating the gas absorber and copper nanoparticle-modified screen-printed graphene electrode within the same device for selective capturing. This novel gas sensing device could be applied to determine NOx gas in various gaseous samples, such as air and exhaust gases from cars with high accuracy and reliability. Lastly, an ePAD coupled with colorimetric detection was demonstrated for the biological sensing of salivary thiocyanate. Here, the microcapillary grooves fabricated on a paper device functioned as a microcapillary pump to facilitate the viscous salivary transportation along the microfluidic channel without requiring for sample pretreatment steps/bulky instrumentations. All in all, these ePAD formats exhibited good performances for the practical analysis and allowed for further development of an advanced platform.
