Purging The Pump - Agilent Technologies 1290 Infinity LC System System Manual And Quick Reference

Purging the Pump

The purging procedure is described for the 1290 Infinity Binary Pump. It can
be executed in an equivalent way for the 1290 Infininty Quaternary Pump.
• After the pump has been primed for the first time.
• When the pump is to be purged with fresh solvent before using the system,
• If the pump has been idle for a few hours or more (air may have diffused
• If the solvent reservoirs are refilled, and the pump requires purging to fill
The inlet tubes to the pump should already be full of solvent. If the inlet tubes
are partially or totally dry, follow the full priming procedure (see
Pump"
The purge valve allows both pump heads to be connected to waste at the same
time and to purge at their individual maximum flow rates of 5 ml/min, giving a
total purge flow of 10 ml/min with 50/50 composition.

the system with fresh solvent. If different solvents are to be used, ensure
that the new solvent is miscible with the previous solvent and if necessary
use an intermediate step with a co-miscible solvent (isopropanol is often a
good choice, check with a solvent miscibility table).
on page 83).
When working with these substances observe appropriate safety procedures (for
example by wearing goggles, safety gloves and protective clothing) as described in
the material handling and safety data sheet supplied by the vendor, and follow good
laboratory practice.
The volume of substances should be reduced to the minimum required for the
analysis.
Do not operate the instrument in an explosive atmosphere.
