新标准今日实施！15分钟搞定血液、尿液中乙醇、甲醇、正丙醇、丙酮、异丙醇和正丁醇的测定 GB/T 42430-2023

前言

《血液、尿液中乙醇、甲醇、正丙醇、丙酮、异丙醇和正丁醇检验》（GB/T 42430-2023）国家标准今日（2024年3月1日）起实施，该标准适用于五种醇类物质及丙酮的中毒、死亡检验、医疗急救检验、科学研究等其他更为广泛的场景。

新标准明确了“双柱系统”的刚性要求，避免了因为不同化合物在一种性质的色谱柱上可能呈现相同的保留时间而导致结果可能误判的情况发生。

本应用介绍了SCION(赛里安)456i气相色谱仪搭配双FID检测器，以及全自动顶空进样器的检测方法（以下简称“血醇”）。方法中使用专业的Rtx BAC1、Rtx BAC2气相色谱柱和Rtx BAC PLUS1、Rtx BAC PLUS2气相色谱柱，搭配使用“1/16 to 0.4mm双孔石墨压环”连接方式。

▼ 表2-2 血醇在BAC2色谱柱峰面积RSD

▼ 表2-3 血醇在BAC Plus1色谱柱峰面积RSD

▼ 表2-4 血醇在BAC Plus2色谱柱峰面积RSD

结论

本应用采用SCION 456i-FID气相色谱仪，结合全自动顶空进样器以及Rtx BAC1、Rtx BAC2气相色谱柱和Rtx BAC PLUS1、Rtx BAC PLUS2气相色谱柱，搭配使用“1/16 to 0.4mm双孔石墨压环”连接方式的检测方法。

此方法使用Rtx BAC系列色谱柱可在15分钟完成分析，同时完全满足国家标准（GB/T 42430-2023）《血液、尿液中乙醇、甲醇、正丙醇、丙酮、异丙醇和正丁醇检验》中的顶空-气相色谱检验方法。
