The lifetime of the multi-channel gradient valve can be maintained by

 

regularly flushing the valve, especially when using buffer solutions. If using

 

buffer solutions, flush all channels of the valve with water to prevent

 

precipitation of the buffer. Salt crystals can be forced into an unused channel

 

and form plugs that may lead to leaks of that channel. Such leaks will interfere

 

with the general performance of the valve

 

When using buffer solutions and organic solvents in the Agilent 1100

 

Quaternary Pump it is recommended to connect the buffer solution to one of

 

the bottom ports and the organic solvent to one of the upper gradient valve

 

ports. It is best to have the organic channel directly above the salt solution

 

channel (e.g., A - salt solution, B - organic solvent).
