Table 11. Possible Remedies for Solvent Contamination
You may have a leak that is allowing solvent vapors to get into the TSQ 9000 instrument. Use a spray gas, such as Tetrafluoethane, to
check for leaks and then fix them. See
Optimize the GC method to separate the solvent peak from the area of interest in the chromatogram. The following compounds may have
been introduced during sample injection, a cleaning or autosampler rinsing solvent. The following commonly used solvents have ions at
the listed m/z:
• Acetone (m/z 43, 58, 59)
• Hexane (m/z 41, 43, 56, 57, 58, 85, 86)
• Methylene chloride (m/z 84/83)
• Toluene (m/z 91, 92)
• Trichloroethane (m/z 151, 153)
• Xylene (m/z 105, 106)
