Nitrilotriacetic acid was separated (as its tri-n-butyl ester) from twenty-four other fatty, phenolic and polycarboxylic acids, using prepacked commercial OV-210 columns. Quantitative analysis down to 0.010 mg nitrilotriacetic acid per liter was demonstrated. The molar responses and retention times of the acids, relative to phthalic acid, were determined.
使用预填充的商用OV - 210柱，从其他24种脂肪酸、酚酸和多元羧酸中分离出次氮基三乙酸（以其三正丁酯形式）。已证明可进行低至每升0.010毫克次氮基三乙酸的定量分析。测定了这些酸相对于邻苯二甲酸的摩尔响应值和保留时间。
