Flow Meter Settings - Thermo Scientific Dionex UltiMate 3000 Series Operating Instructions Manual

4.5.2 Flow Meter Settings

Relevant only for the NC pump
To be able to use a certain solvent with the NC pump, consider the setting for the
respective flow meter:
• With the ProFlow flow meter, the solvent type must be set (→ see page 70).
• With Classic flow meters, the solvent viscosity must be set (→ see page 71).
Only if the settings are made correctly, the module can deliver exact flow rates and gradients.
As a standard, a list is available in Chromeleon, respectively:
ProFlow flow meter: With the most common solvent types (for example, water,
•
acetonitrile, and methanol), and mixtures (for example, mixture of water and acetonitrile
20:80 (v/v)).
• Classic flow meter: With the viscosity values of the most common solvents (for example,
water, acetonitrile, and methanol) and mixtures (such as mixtures of water and
acetonitrile 50:50 (v/v) or 20:80 (v/v)).
If the solvent that you want to use is not available in the solvent list (ProFlow flow meter)
or viscosity list (Classic flow meters) in Chromeleon, refer to section 5.5.3 Adding
Solvents to the Flow Meter Configuration (→ page 114).
Tip: The steps below refer to Chromeleon 6.80.
Note the following for operation under Chromeleon 7:
• For Classic flow meters, set the viscosity value in the Command window
for the NC pump on the Properties page, as described further down.
• For the ProFlow flow meter, set the solvent type in the Command window
for the NC pump on the Properties page, as described below.
For more information, see the Chromeleon Help.
