Theair inlet valvehasacheckvalvewhichblocksvapors
of the solution inabottle,preventing thevapors from
escaping into the lab. Themobilephasecomposition
remains stable, resulting inconstant retention times.
Thecheckvalve regulates thepressurewhen thenegative
pressure reaches1.5psi or 0.1bar. This small negative
pressurepreventsevaporationof the liquid (lower vaporpressure) and still
guarantees the stabilityof theflow rate. Anegativepressurewhich is toohigh
can influence theaspirationof aconstantflow.
Several testshave indicated that the0.2µmcellulosefilterwill keepmobile
phase liquid freeofbacteriaanddustparticlesover time. If youuseafilter
and still havebacteriagrowth inyour liquid, it is likelydue to thepresenceof
bacteria in thedeionizedwaterused.

Theair inlet valve isnot
suitablewhenhelium
sparging isused.
We recommend that
safetyair inlet valves
and safetyairoutlet
valvesbe replaced
every6-7months to
guaranteecorrect
operationof thecheck
valve.The lifetimeof
thecheckvalveand the
