PickVidsDIY mass spectrometer measures potassium in dietary salt substitute
推荐理由
he tries to explain why it's built the way it is and give you a good basis of the theory of operation.
说明
这是2019年由Applied Science发布的一部演示，主题归在Chemistry。它讲的是diy mass spectrometry这一支里的具体问题，而不是把整个领域扫一遍。适合已经能看懂基本术语、想继续往下走的人。内容上可以概括成：Ben Krasnow of Applied Science builds and operates a simple mass spectrometer, using it to measure potassium isotopes in a salt substitute. He explains the design choices and the theory behind it.这些读者给出的理由，核心是：Recommended as an expert-made DIY build that explains why the apparatus is designed as it is, though one commenter notes a missing baseline run.讲法不绑某一条新闻，过几年仍然可以当材料看。从2020年到2023年，有3位不同的读者在3个不同月份把它推荐出来，其中明确叫别人去看的有0次。适合先看结果再决定要不要深挖的人。先看它做成了什么。如果已经会了基本定义，就把注意力放在它怎么把diy mass spectrometry变成能跟着复述的例子。
