Intuvo 9000 GC Column Maintenance

Columns

Many types of Intuvo 9000 GC columns can be used with the MS, but there are
some restrictions.
During tuning or data acquisition, the rate of column flow into the MS should
not exceed the maximum recommended flow. Therefore, there are limits to
column length and flow. Exceeding recommended flow will result in
degradation of mass spectral and sensitivity performance.
Remember that column flows vary greatly with temperature, requiring
measurements of the actual flow to be taken. Use
acceptable column flow.
