The CS3040, LC-MS Source Contamination
Minimizer™ (PHOTO).
Automatically divert concentrated peaks away from most any brand MS source to reduce or
eliminate MS inlet port clogging, contamination and down time. Will not add to your delay
volume or compromise your separations.
AUTOMATED WATCHDOG FOR OPEN-ACCESS SYSTEMS : This device monitors your UV detector's output
so that it can divert the solvent flow away from your MS inlet if the UV signal exceeds a
pre-set value that you enter into the controller (usually a high mAU value for a very
concentrated sample peak) . The diverted flow stream can be sent to waste while an
optional trickle flow of solvent can be supplied to the MS inlet (requires a second pump).
When the signal falls below the user set-point the valve will return normal flow to the MS
inlet. This system is made up of two separate modules. One module houses a single SS high
pressure valve with electric actuation while the other module contains a computer
interface and signal display unit. A 30" long controller cable allows mounting the
diverter valve near your MS source to minimize delay volume (the valve's delay volume is
near 0.1 ul). The controller will accept any analog UV input (-100 to +1999 mv's) and
switch the valve position to waste when the input signal exceeds a user adjusted value
(pre-programmed into the controller). The valve will switch back to the normal flow
position when the input signal drops below the pre-set value. When used with an LC-MS
system the unit can reduce the amount of high concentration samples that enter the MS
inlet thus reducing the potential for plugging.
Unit includes a GLP style chart mark output for
documentation purposes, a high resolution meter to monitor the signal level, remote mount
high-pressure SS valve (0.1 ul delay volume) as well as LED's indicating the current
status. This module can be connected to most any manufacturers LC-MS system and will NOT
compromise your separation.
