文摘
- •
Subcritical fluid nebulizer (ScFN) improves the determination of tin by in atomic absorption spectrometry.
- •
Detection limit by ScFN was 0.008 mg L− 1 increasing the power of detection in 325 compared to FAAS.
- •
ScFN showed that improvements on sample introduction using subcritical CO2 in FAAS are still possible.
- •
ScFN was applied to tin determination in gunshot residues generated after firing four ammunition brands.
