Viscous Sampling Mode - Agilent Technologies Varian CP-8400 Operator's Manual

Viscous Sampling Mode

Viscous mode is designed for samples that either are viscous or are
dissolved in a viscous solvent such as cyclohexanol.
Viscous mode actions are summarized below:
•
The number of pre-injection solvent clean flushes specified in the
method will be performed by drawing a full syringe of solvent from
the specified clean vial and expelling it into the waste cup.
•
The number of pre-injection sample clean flushes specified in the
method will be performed by drawing a full syringe of sample from
the specified sample vial at 1 µL/sec waiting 9.9 sec with the needle
in the sample, and expelling it into the waste cup at 50 µL/sec.
•
If an Internal Standard is used, the Internal Standard will be
withdrawn from the specified source vial at this point – the Internal
Standard air gap will be withdrawn if specified.
•
The volume of sample specified in the Single Method or Method
Sequence Automation will be withdrawn from the specified sample
vial at 1 µL/sec.
•
The system will pause 9.9 sec, and the sample will be injected into
the specified injector at a rate of 5 µL/sec. The syringe will remain in
the injector for 12 seconds before being withdrawn.
•
The post injection clean flushes will be executed.
