一种液相色谱进样通道清洗装置

, 2015
本发明提供了一种清洗液相色谱进样通道的装置，主要由微流量输液泵、压缩空气源、毛细管限流器、液-气切换阀、进样-清洗切换阀、废液收集杯、废液瓶、进样阀、进样口和程序控制器组成。进样完成后，首先用清洗溶液反方向冲洗液相色谱进样通道，将进样过程中滞留在过滤片上的颗粒物反向冲洗掉并排出进样管路；再用微流量气体反方向吹扫进样通道，驱除管路内残留的液体，避免再次进样时对样品的稀释。本发明的装置适用于各类分析级液相色谱仪，包括正相色谱、反相色谱、离子色谱等，以及流动注射分析的进样回路清洗，避免样品交叉污染 ...

超滤处理糖蜜酒精废液中膜清洗方法的研究

, 2012
糖蜜酒精废液超滤处理中膜的污染程度直接关系到膜的通量与使用寿命。本文对超滤法处理糖蜜酒精废液过程中清洗方法进行了研究。试验表明,保持清洗剂40℃温度下,先用反渗透水清洗30 min,再依次用0.2%NaClO溶液清洗30 min,0.2%HNO3清洗30 min,能够较好的降低该废液超滤处理中膜的污染,膜通量率可恢复到91.7%
