批次式氢化物发生原子吸收光谱仪
Small labs testing arsenic only occasionally, or teaching the technique, can rely on a simple batch generator. Each 5–25 mL sample reacts in a 25–100 mL vessel before the hydride passes to a quartz cell at 800–900 °C. It covers As, Se, Sb, Bi, Sn and Hg at 0.1–1 µg/L, handling 10–30 determinations per hour without automation.
