Optimized IC Technique.

System control and programming can be done either directly at each separate unit or via the data system. Even complex instrumentation can be operated without specific training.

Basic System IC S 135

High Performance Pump S 1121.

Dual piston pump with low pulsation. The pump head is made of chemically inert Polyether-Ether-Ketone(PEEK). Programming is done via a step-by-step dialogue through the alphanumeric display. Ramp functions allow gentle start/stop of flow rate to prolong the live time of the ion-exchange resins. Optionally, the pump can be upgraded for gradient elution.

Conductivity Detector S 3111.

With its microprocessor controlled signal processing, combined with a newly developed cell design, the conductivity detector S 3111 is one of the most sensitive instruments available for the determination of ions by Ion Chromatography. The temperature of themicro cell is kept extremely constant, and this cell is Convincing by its fast response time and long time stability, no matter if run in combination with suppression reaction or in direct mode with electronic suppression of the background conductivity. The dynamic ranges(0,3 us to 10 ms0 allow to determine extremely high and low concentrations in one single analytical run.

IC Module S 4260 A/B.

These two modules hold all components to perform Ion Chromatography, with the shortest flow connections possible. Inert injection valve, column oven for extremely constant control of four selectable temperatures, micro conductivity cell, micro suppressor columns with electrically actuated selection valve, inert regeneration solutions, reagent organizer, and controlling unit with panel for programming regeneration cycles. All fluid connections

In the column oven are easily accessible, so column or method changes can be done without difficulty.

AutoSampler S 5200

Short analysis times are very advantageous for routine analysis, especially when sample throughout can be increased by automatic sample injection. TheSykam Autosampler S 5200can handle up to 120 samples for single or multiple injections. Sample sequence is variable due to programmable x-y-z access to the vials. A priority sample feature is implemented for maximum versatility. Automatic dilution and variable injection mode as optional features help to reduce valuable sample preparation time.

Sykam Data System.

Configurable for ion chromatographic applications, this system is capable to control the entire Ion Chromatograph in the windows environment. Automatic integration, calibration with calibration curve analysis, freely configurable documentation of the results in reports with or without sample chromatograms and method parameters, as well as spread sheet documentation of an entire sequences result, all these are features of this most flexible data system. Not to mention features like manual chromatogram editing, data exchange with other programs, and system security and system suitability functions.

ElectroChemical Detector.

The electrochemical detector is an extremely sensitive detection system with high specifity todifferent substances, depending on the working electrode used. For example: pulsed amperometry using a gold electrode for carbohydrate determination, potential-free measurement of cyanide and sulfide with a silver electrode,oxidation of amines or phenoles by a glasssy carbond electrode,or reduction of peroxides employing a platinum working electrode.

Photometer S 3205

Due to variable wavelength programming from 195 nm to 800 nm and its single or dual wavelength capability the UV/Vis photometer S 3205 ideally matches the requirements in Ion Chromatography to detect separated compounds separated compounds directly or following derivatization after separation.

Transition Metals.

With a complexing eluent(tartaric acid) transition metals, lanthanides, and actinides can be separated on a strongly acidic cation-exchange resin partially even according to their different valences. Photometric detection at 520 nm is performed after reaction with pyridylazoresorcinol(PAR). This method can be used not only for analytical purposes, but also for preparative clean-up of radio nuclides before radio activitymonitoring

Boric Acid.

Following separation by ion exclusion (LCA E01) a mannite solution is continuously added to the eluate. Boric acid reacts with the carbohydrate to form an ionic complex detectable by conductivity detection.

Carbohydrates.

For the determination of carbohydrartes as cuprous bicinchoninate complexes a high temperature reactor is needed, since reaction occurs optimally at 120C. The complexes are detected at 500 nm. The separation is performed by using a boric acid gradient program.

Injection value for standard addition.

Eluent Change.

Different eluents can be selected by a 6 positions valve(either manually or by motor actuation) to flush the column or to change the analytical method.

COLUMN CHANGE

By a 6 positions motor valve a flush channel and up to five different columns located in the column oven can be selected. The column outlets are connected to one or several detectors. Since the columns remain equilibrated with their respective eluent, fast method change is feasible

CONCENTRATION OF 5 ML ULTRA PURE

WATER ON A CONCENTRATOR COLUMN WITH

THE FOLLOWING SEPARATION(LCA A 14)

AND CONDUCTIVITY DETECTION AFTER SUPPRESSOR REACTION.

SAMPLE SITES.

To draw samples from varying sites for on-line detection and/or to select different standard solutions motor valves with six or ten positions are available.

CONCENTRATION

Using a small concentrator column connected to a 6 way/2 positions motor valve dilute samples can automatically be concentrated by a dosing pump eluted into the analytical system.
