In bromate determination with the tri-iodide method, the tri-iodide is
partially absorbed by the PEEK capillary, which leads to peak widening and
a lower detection limit. Therefore, for this application, we recommend to
use the PTFE capillary (6.1803.150).
To connect the capillaries, you need the following accessories:
￭
the long PEEK capillary (6.1831.100)
￭
the capillary cutter (6.2621.080)
￭
If the reagent is delivered via high pressure pump: the backpressure
column 6.1015.100 Metrosep BP 1 Guard/2.0
1 Connect the reactor inlet capillary
￭
Attach the column outlet capillary (13-1) to one of the two Y con-
nector inlets.
￭
Connect the Y connector output and reactor input with a short
section of the 6.1831.100 PEEK capillary (13-2).
2 Connect the reagent inlet capillary
￭
For reagent delivery, attach a section of the 6.1831.100 PEEK
capillary to the second Y connector inlet.
￭
Attach the backpressure column (13-5) at he other end.
￭
Attach another section of the 6.1831.100 PEEK capillary to the
other end of the backpressure column (13-4).
3 Connect the reactor outlet capillary
￭
Attach a section of the 6.1831.100 PEEK capillary (13-3) at the
reactor output.
Inserting the reactor plate (6.2845.100)
To insert the reactor plate, you need the 6.2621.140 hexagon key 2.5
mm.
