摘　　要：制作了适用于将海水样品直接进样喷入ICP焰的高盐雾化器。连续进样喷雾12分半钟不堵塞。测定了海水中的元素Sr、Ba、P、B、Ca、K、Li的检出限（DL）和BEC值．其结果相当于或优于ARL－MDSN高盐雾化器的DL和BEC值．A hish dissolved salts contents nebulizer suited for introducing seawater samples to ICP torch wasmade up. The nebulizer could continuously nebulize seawater samples into the ICP torch for 12. 5minutes without blocking up. Detection theits (DL) and background equivalent concentration(BEC)of Sr,Ba,P,B,Ca,K,Li in seawater samples were determinated. The determinded (DL) and (BEC)by this nebulizer were similar or better than (DL) and (BEC) determined by high dissolved salts contents nebulizer ARL-MDSN.
