Hi guys,
You know how mass spec consists of electro spray and and electron impact ionisation. Which one do I write abt ? I’m doing a past paper and for Zn it said high voltage only 2 marker and for rubidium 2 marker it says you need to write abt a hollow needle. I’m confused ! How do i know when to write abt the needle or not?

As far as I'm aware you can write about either one of them unless they specifically ask for a method - I like to go for electron impact, but on the 2019 paper it specifically asked for electrospray (so I was a bit panicky jkshdfldhj) of course I do AQA but that's my understanding ^^
