Enabled
Enables SIPS use - default is 'No'.
Neb. uptake rate
Controls the maximum pump speed. Although expressed in mL/min, the actual
flow rate may be less than this, depending on tube condition, solution viscosity etc.
Ensuring the nebulizer uptake rate exceeds the number entered guarantees
correct pump operation (Beware subsequent nebulizer blockages, which may
invalidate this condition).
Minimum sample DF
Defines the minimal sample dilution factor to be used. Primarily intended for
where the majority of samples are suspected over-range. This will prevent
unnecessary dilution factor changes, thus speeding up sample throughput.
Prime time
Defines the SIPS pre-read delay, which is the time required to pump solutions
introduced with SIPS through the pump tubing from the solution vessel to the T-
piece.
Pump delay time
Defines the time taken for the sample absorbance to reach equilibrium after a
change in pump speed and for the signal to stabilize. Further information on how
to use SIPS is outlined in the Operation section – see Page 67.
