摘要
建立HPLC法测定WS-硫化树脂的方法。采用分子排阻色谱柱(PLgel 3μm MIXEDE 300×7.5mm),以N,N-二甲基甲酰胺(DMF)为流动相,流速1mL·min^(-1),柱温50℃,在283nm处进行检测。分析结果表明,WS-硫化树脂脂线性范围为3.45~100μg·mL-1(r=0.999),且24h之内稳定性良好。该方法重复性好,具有方法简便、快速和准确的优势。
An H PLC method is established for the determination ofWS-curing resin. A PLgel 3 μm MIXEDE（300 × 7. 5mm）column, a mobile phase of D M F, the flow rate of lm L · min^-1 , a column temperature of 50℃and a detection wavelength of 283nm was applied in the present study. This analysis result showedthat, the linear range of WS-curing resin was within the range of 3. 45-100μg · mL^-1 （ r = 0 . 999） ,the determinationresults were stable within 24 hours. The method is simple, quick, accurate and repeatable.
