Nanometer SiO(2) was coated onto the inner wall of a slotted quartz tube atomizer (STAT) and then was used as a new atomizer (NSC- STAT) for the determination of Zn and Cu by flame atomic absorption spectrometry (FAAS). Compared to conventional STAT-FAAS, the analytical performance of NSC-STAT-FAAS was improved as follows: (a) the linear range of calibration curves was expanded from 30.0-200.

- - A new atomizer (NT-QTA) was created by coating a T-shaped quartz tube with nanometer-sized TiO(2) particles, enhancing the detection of mercury (Hg) and selenium (Se) using hydride generation atomic absorption spectrometry (HGAAS).
- - The NT-QTA showed improved analytical performance, with broader calibration ranges and lower characteristic concentrations for both Hg and Se compared to traditional methods.
- - The enhanced technique successfully eliminated interference from arsenic (As) and was applied to measure Hg and Se levels in herbal medicines and hair samples.
