西班牙介绍了一种用ICP-AES法测定钢中硼的快速可靠的方法。该法是基于在把45μl甲醇喷入20μl样品后,在浓硫酸和磷酸介质中,间歇性地产生了硼酸甲酯。用流速为430ml/min的Ar载气把气态的硼酸甲酯和过量甲醇通过中间管送入ICP的喷射中,而
Spain introduced a rapid and reliable method for the determination of boron in steel by ICP-AES. This method is based on the intermittent generation of methyl borate in concentrated sulfuric acid and phosphoric acid medium after spraying 45 [mu] l of methanol into 20 [mu] l of sample. Argon gas at a flow rate of 430 ml / min was used to deliver gaseous methyl borate and excess methanol through an intermediate tube into the jet of ICP and
