1 Introduction

1.1 Instrument description

The 889 IC Sample Center is a robust Autosampler for high sample through-

put, optimized for the challenges of the modern analytic laboratory. Its

greatest advantages are speed and small sample volumes.

Special features:

￭Control of syringes with high resolution. This enables very high precision

during injections.

￭The control per PC software makes operation readily comprehensible. A

context-sensitive online Help function is available for every window and

every dialog.

￭As a means of enhancing safety, no needle movements are carried out

when the door is open.

￭The optional sample cooling guarantees consistent results.

Standard micro titer plates (high or low form) or sample racks can be used.

The same plates or racks must be present in the left-hand and right-hand

loading drawer.

1.1.2 Instrument components

The 889 IC Sample Center has the following components:

￭2 sample racks

Each for 48 vials.

￭Needle arm

With air needle and drives for horizontal and vertical positioning.

￭Injection valve

With six connectors and two switching positions (LOAD and INJECT)

￭Syringe module

For aspirating and transferring the samples.

￭Cooling module (optional)

For cooling the samples.

￭USB connector

For the connection to a PC.

￭I/O interface

For output of an inject marker signal.

1.1.3 Intended use

The 889 IC Sample Center is designed for usage as an automation system

in analytical laboratories.

This instrument is suitable for processing chemicals and flammable samples.

The usage of the 889 IC Sample Center therefore requires that the user has

basic knowledge and experience in the handling of toxic and caustic sub-

stances. Knowledge with respect to the application of the fire prevention

measures prescribed for laboratories is also mandatory.

1.2 About the documentation

Caution
