12 To view the chromatogram while the method is running, touch GRAPH. (See
Figure 4-39.) Alternately, use the arrow keys to highlight GRAPH and push
OK SEL.
NOTE: This screen will also state the TIC Max, the current TIC and the time
the method has been running.
NOTE: Touching the blue compound identification above the chromatogram
will display its Synonym and Exposure Limit information.

13 When the TIC begins to increase, move the probe away from the sample of
interest. Continue the run until the TIC level returns to the initial background
TIC level that was noted in Step 8 on page 4-20. (See Figure 4-40.)
NOTE: Monitor the side bar on the HAPSITE ER screen for guidance. The bar
rises as the TIC increases and green signifies that the proper sampling
distance is being maintained. To avoid saturation, remove the probe
from the sample when the bar increases and turns yellow. If saturation
occurs, the side bar will turn red and the TIC will be above 60 million.
