Chromium ore samples were fused by alkali and then leached out by hydrochloric acid. After the analytical lines of the elements were selected, the conditions of sample uptake, carrier gas flow, cooling gas flow and RF power were optimized with the system of SeaSpray nebulizer and cyclone spray chamber, based on the principle of best signal stability. The determination of chromium, aluminum, iron, magnesium and silicon in chromium ores was fulfilled.

铬矿石样品经碱熔融和盐酸浸取后，选用SeaSpray雾化器和旋流雾室，选定了待测元素的分析线，以信号的稳定性为原则，优化了样品提升量、载气流量、冷却气流量和入射功率，实现了电感耦合等离子体原子发射光谱法对铬矿石中铬、铝、铁、镁和硅等主量成分的测定。
