请问：ssc 缓冲液的 配方！有谁配置过吗

-----------------配方(20x ssc)~~-------------

氯化钠3M(175 g/liter)

柠檬酸钠03 M(88 g/liter)

-----------------程序(20x ssc)---------------

3 M NaCl (175 g/liter)

03 M Na3citrate·2H2O (88 g/liter)

Adjust pH to 70 with 1 M HCl

先加3M的氯化钠

再加03M的柠檬酸钠

最后用1M盐酸把pH调整到70

-----------------为什么----------------

用这个可以出来的阿

pH=PKa+log10( [A-]/[HA])

柠檬酸钠:弱酸

氯化钠:共轭碱

弱酸+ 共轭碱= 缓冲剂!~~~

此文件夹不可删除，可以说它是一个像锁链一样把你的F盘与C盘连在一起（- -具体意思不好表达），打个比方：所有电脑外来程序都需要进行注册（就是注册表）不注册用不起来就这样，那么那个文件就像这样只是进行绑定连接如果你想删掉那就格式化就行了，360强力删除也可以试试自己看吧文件或盘子无法读取就不要怪我了
