SQD マススペクトルが1Daずれる - WKB124371
Article number: 124371
SYMPTOMS
- The mass spectrum near SQD m/z 1500 shifts by 1 Da toward the larger side
ENVIRONMENT
- SQD
CAUSE
Because the cone voltage is not at optimum value, the isotope is larger.
FIX or WORKAROUND
- Optimize the cone voltage.
- Usually, if m/z is large, set the cone voltage higher.
