FIGURE 12 – CHROMATOGRAPH OUTPUT EXAMPLE

Double left clicking on the gas chart will bring up a select tool that changes color and is “stuck” to the tip of the

cursor. Also at the tip of the cursor is a green information box that displays the time in minutes. If the cursor

goes to the left of the geolograph tick marks, the green information box displays the depth. This is useful in

selecting a range of feet or minutes of data. By double clicking on a second point on the Gas Chart, you have

just selected a range of data, and the Select Items Box will appear.

Examine Raw Chromatograph This

button allows the user to see a

close-up view of the selected

chromatograph output. Left

clicking and holding on the

chromatogram will allow the user to

adjust the trace up and down on

the display window. If the trace is

too large or too small, the user can

adjust the overall visual size in the

Program and Equipment Setup

Screen, under the Chromatograph

Tab. When the user is satisfied

with the display, a print can be

made of the chromatogram.

The peak search times are shown as heavy-colored overlays on the chromatograph curve. Each time-window

is centered on its associated vertical line.

The data for the particular chromatogram is available to the right of the chromatogram. If a particular peak

timing is off, or is incorrectly labeled, then all the user has to do is click on the Set Cx peak, place the cross

hairs over the correct peak, and DOUBLE CLICK on the peak to set the new timing window for that

component.

To see the previous separation, hit the Previous button. To see the next separation, hit the Next button.

Calibrating or adjusting the flow rate:

If you want to calibrate the flow rate, get a flow meter. The best one to calibrate with is a clear plastic

flowrater. It should be labeled 0 - 5 LPM. Omega Part number FL-2039.

From a console connection to the Bloodhound type in "calibrate flow" and enter.

This will put the Bloodhound into a calibration mode that will allow you to adjust the flow.

Rotate the black knob on the face of the Bloodhound clockwise to increase the flow rate. Adjust to 1LPM on

the plastic flowrator using the external flow meter.

Wait until the process times out. At that time the Bloodhound will internal electronic flow meter will have been

calibrated.

To just manually adjust the flow rate of the Bloodhound, set register 10 to a pump power number from 1 -

100. This will set the sample pump percent motor power level. The Bloodhound will not be able to

automatically adjust the flow rate when the flow rate is in this override mode.
