A 600 MHz NMR has a signal to noise ratio of 1000 for a proton standard. The 400 MHz NMR has a signal to noise ratio of 200 for a proton standard. If it takes 20 minutes to get an acceptable signal to noise ratio for a sample on the 600 MHz NMR, how long will it take you to achieve the same signal to noise ratio on the 400 MHz NMR?

Question
A 600 MHz NMR has a signal to noise ratio of
1000 for a proton standard. The 400 MHz
NMR has a signal to noise ratio of 200 for a
proton standard. If it takes 20 minutes to get
an acceptable signal to noise ratio for a
sample on the 600 MHz NMR, how long will it
take you to achieve the same signal to noise
ratio on the 400 MHz NMR?
