    Frequently Asked Questions
    Q What is the wavelength range of this flame AAS instrument?
    The instrument covers a wavelength range of 190–900nm, making it suitable for a wide variety of elemental analyses across both UV and visible spectral regions.
    Q What type of burner and nebulizer does this AAS use?
    The instrument is equipped with a 10cm single slot all-titanium burner and a high efficiency glass nebulizer with a metal sleeve. The nebulizer has a sucking-up rate of 6–7ml/min, ensuring reliable sample introduction.
    Q How does the background correction system work?
    The instrument uses a D2 lamp background correction system. At an absorbance of 1A, the background correction capability is better than 30 times, effectively reducing interference from non-specific absorption during measurements.
    Q Can this instrument be used for hydride analysis?
    Yes. The instrument supports function expansion — a hydride vapor generator can be connected to enable hydride analysis, extending its analytical capabilities to elements such as arsenic, selenium, and mercury.
    Q What data processing functions are available?
    The built-in microprocessor provides automatic calculation of mean, standard deviation, and relative standard deviation. It also supports automatic curve fitting with 3–7 standards, sensitivity auto-correction, and allows printing of measurement data, working curves, signal profiles, and analytical conditions.
    Q What are the detection limit and characteristic concentration for copper (Cu)?
    Using an Air-C2H2 flame, the characteristic concentration for copper (Cu) is ≦ 0.025mg/L and the detection limit is ≦ 0.006mg/L, demonstrating high sensitivity suitable for trace metal analysis.
