1 Introduction
1.1 Instrument description
The 886 Professional Thermostat / Reactor is an instrument of the
Metrohm Professional line of instruments, which was conceived to be
used for two different functions.
The main function of the 886 Professional Thermostat / Reactor is detection preparation in an IC system with photometric detection. In IC systems
with photometric detection, a post-column derivatization (PCR) is required
for most applications. An IC system with photometric detection consists of
an 850 Professional IC instrument, the 886 Professional Thermostat /
Reactor, and the 887 Professional UV/VIS Detector. Additionally, 872
extension modules can be used to transfer reagent solutions and/or for
sample preparation.
1 Introduction
The second function of the 886 Professional Thermostat / Reactor is that
of a column thermostat. A 872 Extension Module – IC Module together
with an 886 Professional Thermostat / Reactor provide all the functions of
an IC instrument. By adding a suitable detector, an isocratic analytical system can be built without a dedicated IC instrument.
The 886 Professional Thermostat / Reactor is available in two model versions each with different set of accessories, to support each function:
￭ 2.886.0110 Professiopost columnnal Reactor
For the use as a pre-column or post-column reactor. 886 Professional
Thermostat / Reactor with accessory set 6.2845.100 consisting of a
reactor plate with one reactor. For sophisticated applications, the reactor plate can be equipped with up to four reactors.
￭ 2.886.0210 Professional Thermostat
For the use as a column thermostat: 886 Professional Thermostat /
Reactor with accessories set 6.2845.600 consisting of a column plate
with a fitted column block for two separation columns and a preheating capillary.
These accessories sets can be inserted into the the oven of the 886 Professional Thermostat / Reactor, which can be heated up to 150 °C as a maximum.
The oven of the 886 Professional Thermostat / Reactor can be heated up
to maximum 150 °C if it is empty. With the accessories for the Professional Reactor (6.2845.100) inserted, the maximum temperature is 120 °C;
with the accessories for the Professional Thermostat (6.2845.600) inserted, 80 °C.

1.2 Intended use
The 886 Professional Thermostat / Reactor is operated with MagIC Net
software. It is connected via a USB cable to a PC on which MagIC Net is
installed. The software automatically recognizes the instrument and
checks its functional readiness. MagIC Net controls and monitors the
instrument, and documents heating power and reagent flow rates in a
database.
Additional information on operating the software can be found in the
document "Tutorial for MagIC Net" or in the online help.
1.2 Intended use
The main function of the 886 Professional Thermostat / Reactor is postcolumn derivatization (PCR). In the process, chemicals are brought to a
reaction in a heated atmosphere. It is also possible to perform pre-column
reactions.
This instrument is suitable for processing chemicals and flammable samples. The usage of the 886 Professional Thermostat / Reactor therefore
requires that the user has basic knowledge and experience in the handling
of toxic and caustic substances. Knowledge with respect to the application of the fire prevention measures prescribed for laboratories is also
mandatory.

3.4 Capillary connections in the IC system
This chapter contains general information concerning the capillary connections in the IC instruments and systems.
Generally speaking, capillary connections between two components of an
IC system are made up of one connection capillary and two pressure
screws with which the capillary is connected to the respective components.

(6.2744.070)
For use on the high pressure pump, the
purge valve, the inline filter, the pulsation
absorber, the guard column and the separation column.
In order to keep the dead volume as low as possible, capillary connections should generally be as short as possible.
For an improved overview, capillary and tubing connections can be
bundled with the 6.1815.010 spiral band.

3.4 Capillary connections in the IC system
Connection capillaries
PEEK capillaries and PTFE capillaries are used in the IC system.
￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
PEEK capillaries (polyetheretherketone)
PTFE capillaries (polytetrafluoroethylene)
PEEK capillaries are temperature-resistant up to 100°C, stable under pressure up to 400 bar, flexible, chemically inert and exhibit an extremely
smooth surface. They can be readily cut down to the desired length with
the 6.2621.080 capillary cutter.
Usage:
￭ PEEK capillaries (6.1831.010) with an internal diameter of 0.25 mm for
the entire high pressure range.
￭ PEEK capillaries (6.1831.030) with an internal diameter of 0.75 mm for
sample handling in the ultra trace range.
PTFE capillaries are transparent and enable visual tracing of the liquids to
be pumped. They are chemically inert, flexible and temperature-resistant
up to 80°C.
Usage:
PTFE capillaries (6.1803.0x0) are used for the low pressure range.
￭ PTFE capillaries with internal diameter of 0.5 mm for sample handling.
￭ PTFE capillaries with internal diameter of 0.97 mm for sample handling
as well as for rinsing solutions (they do not have to be in the scope of
delivery of the instrument).
Capillary connections
In order to achieve optimum analysis results, capillary connections in an IC
system must be absolutely tight and free of dead volume. Dead volume
occurs if two capillary ends connected to each other do not fit exactly,
thus allowing liquid to escape. There are two possible reasons for this:
￭ The capillaries do not have exactly cut edges.
￭ The two capillary ends do not completely meet.
One prerequisite for dead volume free capillary connection is, that both
capillary ends are cut exactly plane. Therefore we recommend only to cut
PEEK capillaries with the capillary cutter (6.2621.080).
Creating dead volume free capillary connections
To create dead volume free capillary connections, proceed as follows:
Slide the pressure screw over the capillary. Ensure that the capillary
1
protrudes 1–2 mm from the tip of the pressure screw.

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
3 Installation
Plug the capillary all the way into the connection or coupling until
2
the stop.
Only then start turning the pressure screw, while keeping the capil-
3
lary pressed in space.
Colored sleeves for PEEK capillaries
The enclosed set of varicolored sleeves for PEEK capillaries (6.2251.000)
serves to easily differentiate the various flows of liquid in the system
through color coding. Each capillary leading a given liquid (e. g. eluent)
can be highlighted with sleeves of the same color.
To highlight a capillary, proceed as follows:
Slide a sleeve of a selected color over a capillary an move it to an
1
easily visible position.
If the capillary heats up, the sleeve shrinks and adapts to the form of
the capillary.
3.5 Installations on the rear of the instrument
3.5.1 Connecting the leak sensor
The leak sensor detects escaping liquid which collects in the base tray of
the instrument.
To activate the leak sensor, the leak sensor connector plug (8-2) must be
connected, the instrument switched on and the leak sensor switched to
active in the software.
Connecting the leak sensor
￭ Pull the cable of the leak sensor (8-3) out of the rear of the base
1
tray.
￭ Plug the leak sensor connector plug (8-2) into the leak sensor
connection socket (8-1) on the rear of the instrument.

oven is not heated up higher than the standard operating temperature of
the column. You can also use columns without chip, in this case you have
to set the maximum oven temperature manually.
The second bore hole of the column block can also hold additional columns and/or guard columns with a total length of 150 mm. For applications requiring a 250 mm column, you can combine a 150 mm iColumn
with a second 100 mm column and an on column guard column. The following figure illustrates how the preheating capillary and the columns are

Although this is prevented to a great extent by design measures, the
mains plug should be unplugged immediately if aggressive media has
penetrated the inside of the instrument, so as to avoid serious damage
to the instrument electronics. In such cases, the Metrohm Service must
be informed.
Spillages of chemicals and solvents should be cleaned up immediately. In
particular, the plug connections on the rear panel of the instrument (especially the mains plug) should be protected from contamination.
6.1.2 Maintenance by Metrohm Service
Maintenance of the instrument is best carried out as part of an annual
service, which is performed by specialist personnel from Metrohm. If
working frequently with caustic and corrosive chemicals, a shorter maintenance interval is recommended. The Metrohm service department offers
every form of technical advice for maintenance and service of all Metrohm
instruments.
6.1.3 Operation
Caution
￭￭￭￭￭￭￭￭
38
In order to avoid disturbing temperature influences, the entire system
including the eluent bottle must be protected against direct sunlight.

￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
6.1.4 Shutting down
If the instrument is not used for a longer period, the whole IC system
(except the columns) must be rinsed salt free with methanol/ultrapure
water (1:4), in order to prevent eluent salts and reagents from forming
crystals which may cause subsequent damage.
Rinsing salt free the IC system
To rinse the system, proceed as follows:
Remove the separation column from the eluent path. Connect the
1
connection capillaries directly with each other using a coupling
(6.2744.040).
Rinse the IC system with methanol/ultrapure water (1:4) for 15
2
minutes.
Rinse with eluent for at least 15 minutes at starting up again and before
connecting the guard column and separation column.
6 Handling and maintenance
6.2 Door
Caution
The door is made of PMMA (polymethylmetacrylate). It must never be
cleaned with abrasive media or solvents.
Caution
Never hold the instrument at the door when lifting or moving.
