化学分析与仪器分析方法比较 化学分析:常量组分(>1%),E0.1%~0.2% 准确度高 依据化学反应,使用玻璃仪器

第一节概述 色谱法早在1903年由俄国植物学家茨维特分 离植物色素时采用。 他在研究植物叶的色素成分时,将植物叶 子的萃取物倒入填有碳酸钙的直立玻璃管内, 然后加入石油醚使其自由流下,结果色素中各 组分互相分离形成各种不同颜色的谱带。这种 方法因此得名为色谱法。以后此法逐渐应用于 无色物质的分离,“色谱”二字虽已失去原来

状态公理:简单可压缩系统,两个独立变量 未饱和水及过热蒸汽,一般已知p、T即可 饱和水和干饱和蒸汽,只需确定p或T 湿饱和蒸汽,p和T不独立,汽液两相 1875年,吉布斯提出了吉布斯相律

Some key facts 2. 8 billion people two in five--stil struggle to survive on less than $2 a dav In 2000, 1. 1 billion people did not have reasonable access to safe drinking water World population will increase from 6.4 billion today to 8.9 billion by 2050

Effect of environmental factors on growth Water availability, pH, temperature, oxygen concentration, pressure, radiation, and a number of other environmental factors influence microbial growth. Yet many microorganisms, and particularly bacteria, have managed to adapt and flourish under environmental extremes that would destroy most organisms

Bob, a student taking 7.012, looks at a long-standing puddle outside his dorm window Curious as to what was growing in the cloudy water, he takes a sample to his TA, Brad Student. He wanted to know whether the organisms in the sample were prokaryotic or eukaryotic
