摘要
叶绿素为判断湖泊水库富营养化程度的重要指标之一,国家在重要湖泊水库安装了叶绿素在线自动监测仪器。本文叙述了叶绿素自动监测分析仪及实验室测定的原理,为解决叶绿素标准样品和质控样品难求的问题,以新鲜菠菜叶为原料、乙醇为提取液,进行叶绿素分析仪性能实验与核查比对实验,可知叶绿素在线自动监测仪器性能良好、稳定可靠。
Chlorophyll is one of the important indicators to estimate the degree of eutrophication of lakes and reservoirs.National installed online automatic monitoring instruments of chlorophyll on major lakes and reservoirs.This paper describes the principle of the measurement of automatic monitoring analyzer and laboratory of chlorophyll.Chlorophyll standard samples and quality control samples are hard to find.To resolve this problem,chlorophyll analyzer performance test and verification comparative experiments were implemented by ethanol extract of fresh spinach leaves as raw materials.The results indicated that the on-line automatic monitoring chlorophyll analyzer is stable and reliable.
