摘　　要：探讨使用离子色谱仪分析油气田地层取样样品的可行性.该方法使用ICS900 型离子色谱仪（配阴离子色谱柱AS19 和阳离子色谱柱CS12A）,同时由自动淋洗液发生器RFC30 产生20mmol/L 氢氧化钾溶液和20mmol/L 甲烷磺酸溶液,流量为1 mL/min.7 种离子测定结果的相对标准偏差为0.87%～3.40%,样品加标回收率为98.00%～104.0%.该方法精密度和准确度满足油气田地层取样样品中阴阳离子的分唐析要求.It was discussed that the feasibility of utilizing ion chromatography to analyze samples of oilfieldstratum. ICS900 type chromatograph was used to analyze samples with anion chromatographic column AS19 and cationchromatographic column CS12A. At the same time,the automatic eluent generators RFC30 produced 20 mmol/L KOHand 20 mmol/L MSA solution. The flow rate of solution was 1 mL/min. Under these conditions,the RSDs were 0.87%–3.40%, and the recoveries were 98.00%–104.0%, which showed that the method was suitable for the determination ofoilfield stratum samples.
