【摘要】:采用配有專(zhuān)用IR5-MCT檢測(cè)器和GPC快速柱的新型凝膠色譜儀GPC-IR測(cè)定超高相對(duì)分子質(zhì)量的聚乙烯試樣的相對(duì)分子質(zhì)量及其分布,對(duì)三個(gè)超高相對(duì)分子質(zhì)量的聚乙烯試樣進(jìn)行分析表征。實(shí)驗(yàn)結(jié)果表明,該新型凝膠色譜儀可進(jìn)行極稀試樣溶液的定量測(cè)定,測(cè)試結(jié)果準(zhǔn)確度高、重復(fù)性良好,操作簡(jiǎn)便,完全滿(mǎn)足定量分析要求,克服了傳統(tǒng)高溫GPC無(wú)法分析超高相對(duì)分子質(zhì)量聚乙烯的難題。
[Abstract]:A new gel chromatograph with special IR5-MCT detector and GPC fast column was used to determine the relative molecular weight and distribution of ultra high molecular weight polyethylene samples. Three ultra high molecular weight polyethylene samples were analyzed and characterized. The experimental results show that the new gel chromatograph can be used for quantitative determination of extremely dilute sample solution. The test results are accurate, reproducible, easy to operate and fully meet the requirements of quantitative analysis. It overcomes the problem that traditional high temperature GPC can not analyze UHMWPE.
