MS scan detects the spectrum of the target compound cleavage; caused by collision energy - WKB74705
Article number: 74705
SYMPTOMS
- MS scan detects the spectrum of the target compound cleavage
ENVIRONMENT
- SYNAPT G2-S
- SYNAPT G2-Si
- Xevo G2-S
- Xevo G2-XS
CAUSE
It collides with the argon gas in the collision cell and decays.
FIX or WORKAROUND
When Collision Energy in the MS Method is set to Off, a 6V collision voltage is applied.
As shown in the figure below, after setting Collision Energy to On, specify a value smaller than 6V (e.g., 3V).
If the problem persists, see the following article.
