At BOC Sciences, we provide professional Atomic Absorption Spectroscopy (AAS) testing services capable of addressing diverse sample types and elemental analysis needs. From routine metal quantification to ultra-trace element detection, we deliver highly sensitive, accurate, and reliable results. Leveraging advanced instrumentation and an experienced analytical team, we tailor testing solutions to each client, ensuring precision and reproducibility. Our services are widely applied in research, materials development, and quality control, earning global recognition and trust for our expertise, technical capabilities, and commitment to high-quality service.
AAS is a quantitative analytical technique based on the characteristic absorption of light by elemental atoms at specific wavelengths. Samples are first atomized using flame, graphite furnace, or gaseous chemical methods, and the absorption of light by these atoms is then measured. The absorption signal is directly proportional to the element concentration, enabling precise quantification. AAS is suitable for analyzing elements ranging from common metals to ultra-trace levels, offering high sensitivity, excellent selectivity, and operational flexibility. It is widely applied in research, materials analysis, and quality control, making it an essential tool in modern laboratories.
We offer the following AAS testing services to support precise analysis of elemental content in your samples.
FAAS utilizes air-acetylene or nitrous oxide-acetylene flames for efficient atomization. It quantifies over 30 common metals, including Cu, Zn, Pb, Ni, Ca, and Mg, as well as high-temperature elements such as Al, Si, Ti, V, and Mo, delivering rapid, reliable results for routine elemental analysis.
GFAAS offers detection limits 10–100 times lower than FAAS, requiring only microliter-scale sample introduction. It is ideal for ultra-trace elements such as Cd, As, Cr, and Ag, providing highly sensitive, precise quantification for research, quality control, and challenging analytical applications.
HG-AAS introduces gaseous hydrides to selectively measure elements including As, Se, Sb, Bi, Sn, Ge, Pb, Te, and Hg. This method improves atomization efficiency, minimizes matrix interferences, and ensures accurate, reproducible analysis for applications requiring trace-level hydride detection.
CVAAS reduces Hg2+ to Hg0 using SnCl2, followed by inert gas transport into the absorption cell. This technique achieves ultra-trace detection down to 0.1 ng L-1, making it highly effective for mercury-specific analysis in environmental monitoring, materials testing, and high-purity applications.
QTA-AAS combines quartz tube atomization with hydride generation to maximize efficiency and reduce matrix effects. It is particularly suited for complex sample matrices, ensuring precise hydride element quantification with high sensitivity and reproducibility across diverse analytical challenges.
DS-GFAAS enables direct analysis of powders, films, and particles without prior digestion. Using milligram-scale samples, it accurately quantifies trace elements in high-purity reagents, plastics, and other solid matrices, offering efficient, reliable results while minimizing sample preparation time.
