Effects of Pressure Variations
Under conditions of
+100
mmHg pressure, the Pump Module
typically exhibits a long-term accuracy offset of approximately
-0.7%
from mean values.
Under conditions of
+300
mmHg pressure, the Pump Module
typically exhibits a long-term accuracy offset of approximately
-4.2%
from mean values.
Under conditions of
-100
mmHg pressure, the Pump Module
typically exhibits a long-term accuracy offset of approximately
+4.4%
from mean values.
Resulting trumpet observation points typically track those of
accuracy; therefore, no significant change in short-term
variations result under these pressure conditions.
Effects of Negative Solution Container Heights
With a negative head height of
-0.5
meters, the Pump Module
typically exhibits a long-term accuracy offset of approximately
-3.1%
from mean values.
Resulting trumpet observation points typically track those of
accuracy; therefore, no significant change in short-term
variations result under negative head height conditions.

RATE (mL/h)
Syringe Module
Trumpet and start-up curves have been provided for
1.0
mL/h
and
5.0
mL/h. Measurements for trumpet curve rates below
1.0
mL/h are not provided because of the difficulty in
measuring extremely small volumes over a large duration of
time. In this case, the linear relationship of the plunger
position and velocity to syringe volume and rate is verified,
and is a function of the accuracy of the design.
