摘　　要：进入ＬＤＰＥ生产线在线工业色谱的样品含有大分子干扰物质，使色谱柱效率下降或失效。本文设计了一种在线样品预处理系统，采用特殊的冷凝过滤器消除干扰。过滤器可以在线再生，连续使用，确保了在线工业色谱的正常运行。The sample into process-GC in LDPE contains some large molecular substance. which makes the GC column uneffective. A special sample pre-treatment system is investigated which minimizes the disturbance with a cooled-filter made of sintered-metal. This sample pre-treatment system can be regenerated in line to ensure the continuous work of GC.
