1 Introduction
1.1 Area of application
The 919 IC Autosampler plus is an autosampler with a wide variety of
applications. It offers the option of fully automated sample series process-
ing. In addition to this capability, the 919 IC Autosampler plus can be sup-
plemented to include the functionality for Inline Ultrafiltration or Inline
Dialysis.
Thanks to its proven USB interface, the 919 IC Autosampler plus can be
integrated into Metrohm instrument systems in a flexible manner. The
instrument is always controlled by means of a high-performance PC soft-
ware, e.g. MagIC Net™ from Metrohm.
1.2 Instrument description
The 919 IC Autosampler plus has the following features:
￭Turntable with interchangeable sample rack. A single-row sample rack
is included in the scope of delivery.
￭Tower with a robust lift. The lift is equipped with a working head to
which a needle holder can be attached.
￭Two-channel peristaltic pump.
￭Three MSB connectors (Metrohm Serial Bus), each for controlling an
800 Dosino, an 801 Stirrer or a Remote Box, etc.
￭Two USB connectors, with which e.g. printers, keyboards, barcode
readers or additional devices, such as Dosing Interfaces, etc., can be
directly connected.
￭Two connectors for a peristaltic or a membrane pump.
￭Stirrer connector on the tower, for propeller stirrer or magnetic stirrer.

1.3 Intended use ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭

1.3 Intended use
The 919 IC Autosampler plus is designed for usage as an automation sys-
tem in analytical laboratories. It is not suitable for usage in biochemical,
biological or medical environments in its basic equipment version.
The present instrument is suitable for processing chemicals and flammable
samples. Usage of the 919 IC Autosampler plus therefore requires the user
to have basic knowledge and experience in handling toxic and caustic
substances. Knowledge with respect to the application of the fire preven-
tion measures prescribed for laboratories is also mandatory.

1.5 Safety instructions
1.5.1 General notes on safety
WARNING
Operate this instrument only according to the information contained in
this documentation.
This instrument left the factory in a flawless state in terms of technical
safety. To maintain this state and ensure non-hazardous operation of the
instrument, the following instructions must be observed carefully.
1.5.2 Electrical safety
The electrical safety when working with the instrument is ensured as part
of the international standard IEC 61010.
WARNING
Only personnel qualified by Metrohm are authorized to carry out service
work on electronic components.

1.5 Safety instructions ￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭￭
4￭￭￭￭￭￭￭￭ 919 IC Autosampler plus
WARNING
Never open the housing of the instrument. The instrument could be
damaged by this. There is also a risk of serious injury if live components
are touched.
There are no parts inside the housing which can be serviced or replaced
by the user.
Supply voltage
WARNING
An incorrect supply voltage can damage the instrument.
Only operate this instrument with a supply voltage specified for it (see
rear panel of the instrument).
Protection against electrostatic charges
WARNING
Electronic components are sensitive to electrostatic charges and can be
destroyed by discharges.
Do not fail to pull the power cord out of the power socket before you
set up or disconnect electrical plug connections at the rear of the
instrument.
1.5.3 Tubing and capillary connections
CAUTION
Leaks in tubing and capillary connections are a safety risk. Tighten all
connections well by hand. Avoid applying excessive force to tubing con-
nections. Damaged tubing ends lead to leakage. Appropriate tools can
be used to loosen connections.
Check the connections regularly for leakage. If the instrument is used
mainly in unattended operation, then weekly inspections are manda-
tory.

1.5.4 Personnel safety
WARNING
Wear protective goggles and working clothes suitable for laboratory
work while operating the 919 IC Autosampler plus. It is also advisable
to wear gloves when caustic liquids are used or in situations where
glass vessels could break.
WARNING
Always install the safety shield supplied with the equipment before
using the instrument for the first time. Pre-installed safety shields are
not allowed to be removed.
The 919 IC Autosampler plus may not be operated without a safety
shield!
WARNING
Personnel are not permitted to reach into the working area of the
instrument while operations are running!
A considerable risk of injury exists for the user.
WARNING
In the event of a possible blockage of a drive, the mains plug must be
pulled out of the socket immediately. Do not attempt to free jammed
sample vessels or other parts while the device is switched on. Blockages
can only be cleared when the instrument is in a voltage-free status; this
action generally involves a considerable risk of injury.
WARNING
The 919 IC Autosampler plus is not suitable for utilization in biochemi-
cal, biological or medical environments in its basic equipment version.
Appropriate protective measures must be implemented in the event
that potentially infectious samples or reagents are being processed.
