QUEST doesn\'t work on GE 1.5T

[Adrien HEINTZ]

Hi,
I use QUEST on GE 3T spectra and it works very well.
On the other hand, as soon as I pass on 1.5T spectrum QUEST no longer works.
Where did the problem come from?

thank you in advance

Dear Adrien,

Could you be more specific?
Did you use the same basis set?

[Adrien HEINTZ]

Thank you for your reply.
I think I use the same basic set.
To be more precise when I create a .ml file with NMRSCOPEB to 3T the software can read the spectrum well and quantify (image1).
When I do the same at 1.5T spectra the quantification no longer works (image2)

3T: 4096pts; 5000Hz
1.5T: 2048pts; 2500Hz

cordially

Adrien

Thank you.

My recommendations:
– you should simulate a new basis set for 1.5T – you can use almost the same settings.
In the tab Scanner select B0 = 1.5 T, in the window sequence please select NS = 2048 and your bandwidth.

Tell me if it helped.

Best regards
MJ

I’ve already done like that : B0=1.5T , NS=2048 and Bandwidth=2500
All of this setup is already done but still doesn’t work…

Best regards

AH
