UHPLCandHPLC Injectors andSwitchingValves
Microbore
ModelC2
valves canbeusedas
injectorsor switchingvalves.
ModelC4
isan internal volume
sample injectorwith sample sizes
ranging from10nl to50nl.
ModelC6
continuousflow injector
isdesigned tomaintainpumpflow
duringmostof the switchingcycle,
virtuallyeliminatingpressure spikes.
ModelC1
isa through-the-handle
(front-loading) injectordesigned
fordirect replacementof existing
competitivemodels. AllModel C1
injectorsaremanual,withposition
feedback standard.
ModelC1CF
isa6port through-the-
handlecontinuousflow injector. An
engravingon the statormaintains
pumpflowbetweenports5and4
duringmostof the switchingcycle,
virtuallyeliminatingpressure spikes.
Because thehandle is integral to
thedesign,allModel C1CFvalves
aremanual,withposition feedback
standard.
