The application of ultrafiltration to sample preparation in the detection and quantification of ethylene glycol in plasma by gas chromatography is described. After addition of the butylene glycol internal standard and ultrafiltration, the sample is directly injected, obviating the need for further dilution. This simple, efficient method of sample preparation is also suitable for more sensitive gas chromatographic measurement of other volatiles.
本文描述了超滤在气相色谱法检测和定量血浆中乙二醇时样品制备中的应用。加入丁二醇内标并超滤后，样品可直接进样，无需进一步稀释。这种简单、高效的样品制备方法也适用于其他挥发性物质的更灵敏的气相色谱测定。
