In
Online
mode, the Analyzer is designed to measure water from a continuous sample
flow. In
Grab
mode, simply insert 40-mL vials into the iOS System. No plumbing change
is required.
Configuring the Sample Inlet and Outlet Ports
Disable the flow from the water source until the sample inlet system is completely
installed and the Analyzer is ready to begin analysis.
To configure the sample inlet and outlet ports
1. Connect the 1/4" Teflon
®
tubing with the in-line filter to the sample inlet on the
iOS or the Sample Inlet Block, depending on the Analyzer’s configuration.
Tighten 1/4 turn past finger-tight with a 9/16" open-end wrench. Do not over-
tighten the nut.
2.
Connect the 3/4" OD waste line tubing to the waste outlet on the sample inlet
system or the Sample Inlet Block by sliding the tubing over the barb fitting.
3.
Place the hose clamp over the waste line and tighten, to secure the connection
to the waste outlet.
4.
Route the waste tubing to an appropriate waste outlet. The waste is gravity-
drained, and thus the waste tubing cannot be routed above the level of the
waste from the waste line to between 50-300 mL/min. The flow rate is
controlled by a needle valve, which is adjusted by the screw on the sample
inlet system. Turn the screw clockwise to decrease flow and counter-clockwise
to increase flow.
NOTE:
Avoid setting a water flow rate that exceeds 300 mL/min,
which may result in poor system suitability verification data.
Cautions
To avoid false TOC readings and possible damage to the Analyzer, always make sure
the sample inlet is open and the DI water reservoir is filled
before
turning on the
Analyzer. Always close the door of the iOS System when not sampling from a vial.
Operation of the Analyzer without the in-line filter on the sample inlet line will damage
the Analyzer and void the warranty. To avoid damaging the Analyzer, install the filter
and replace the filter element as needed.
