SYSTEM DESCRIPTION AND TECHNICAL DATA

GOLD-Method-Evolutionsystem

existing from:

-    126 pump modules

-    168 diodenarray-detector

-    168 scan graphics

-    drip tray and plate

-    ODS-column

-    test mixture

-    bottle rack with 4 bottles

This system is configured specifically for the fully automatic method development.

The pump module 126 for gradient business promotes 0,001 to 10 ml/min.

The one-piston design with electronic real timecompression-compensation guarantees constant and pulse-free river, independently from run means and pressure. The rear piston irrigation prevents the crystallizing out of salt.

In the module 126 integrated is the doublestep for high pressure-page gradient formation mixers dynamic.

Programmable eluent-selectors make the automatic solvent selection from 4 presentations possible per pump.

The diodenarray-Detector model 168 offers following specifications:

-    512 diodes

-    analytic standard river cell:

     11 ul cell volumes, 10 mm length

-    On wish of semi-preparative river cell:

     2 mm length

-    wavelength area: 190 - 600 nm

-    wavelength precision: ± 1 nm

-    spread: Variably from 4 nm as far as to the entire wavelength area

-    2 data canals + 1 reference canals

-    basis line flush: small 1 x 10 (-4) OUCH

-    drift: small 2 x 10 (-3) AU/h

-    measuring area: 0.001 to 1.5 AUFS

-    variable wimple time: 0 - 5 sec

-    throughput: 1, 2, 4, 8 or 16 Hz,

-    autozero

-    Peakrecognition for the scan-function as well as to the control of a party collector

-    scan-types: in freely selectable intervals, at the peakmaximum, to the purity control

-    detection of an impurity,

-    scanrate: 0.5 to 16 Hz

-    spectral spread: small 4 nm

-    real-time scan during the data reception

-    software to the real-time peakpuritysetting: a graphic symbol under the       Chromatogramm shows the number of the impurities

-    per PC, only 1 Diode-Array detectors can be driven in 168

-    existing from:

     Diode-Array detector 168

     Scan-graphik software

A manual system as well as different models of the test giver are available for the test task in 507.

The control, control and data processing of the entire system, system takes place gold software, that is available for computers of the AT-Typs or the IBM PS/2-Serie, over them/her/it.
