On-stream WDXRF Analyzer AR-35

The analyzer is designed for real-time analysis of the chemical composition of streams of slurry, suspensions and solutions and determination of the mass fraction of chemical elements from sulfur S to uranium U. The AR-35 is designed for real-time analysis of the chemical composition of streams of slurry, suspensions and solutions and determination of the mass fraction of chemical elements from sulfur S to uranium U. The analyzer has up to 15 measuring cell for samples, a mobile software-controlled measuring head with an X-ray tube and fixed spectrometric channels for the wave dispersion method (WDXRF) and/or an attachment with a semiconductor detector for the energy dispersion method (EDXRF). The principle of operation is based on the excitation of fluorescence of atoms in a sample by X-ray tube radiation. The intensity of the detected fluorescent radiation with a certain wavelength, selected by the crystal analyzer and recorded by the detection unit, is directly proportional to the mass fraction of the chemical element in the substance under study.

The analyzer AR-35 can be included in the project of an automated system of analytical monitoring (ASAM) with sampling equipment and multiplexer.

Multichannel ensures that there is no measurement error due to pollution of the measuring cel
High expressity and accuracy of the analysis

Multiplexer

Semiconductor detector SSD

Calibration sampling device

It is intended for the selection of representative liquid samples for the purposes of calibration and control of the analysis results.
The sampling work is carried out according to a pre-established program that determines the frequency, duration and number of cut-offs, which are set through the analyzer software. The return of samples to the technological process that have been analyzed for each individual product can be carried out separately.

Capital-purpose spare parts

An optional capital spares parts can be included:

high voltage power supply;
cooling system;
detection unit;
registration unit.

Container for the AR-35 analyzer

In case of absence of a room at the factory the analyzer AR-35 can be placed in a container with the necessary equipment:

lighting facilities;
ventilation system;
fire extinguishing system;
panel equipment;
fire alarm system.

If there is a requirement for fire safety and explosion protection, a special container can be selected.

Multiplexer

It is intended for representative allocation of control pulp samples and pulp supply to the analyzer synchronously with the algorithm of its operation.

Also, multiplexers is intended for switching the flow of the analyzed sample between a flow analyzer and a composite sample filtering device. During sampling for analysis, its representativeness and stabilization of physical parameters are ensured, and the set level of sample material in the averaging tank is maintained. Also, when a sample is accumulated in an averaging tank, a defoaming system is used to ensure uniformity of samples for foam products. Unused material is drained through a drainage outlet to the sample return devices in the process.

The multiplexer is a secondary sampling device with the possibility of autonomous operation. The multiplexer is capable of providing composite (balanced) Sampling without reference to the analyzer operation.

Semiconductor detector SSD

A semiconductor detector can be installed to expand the analytical capabilities of the analyzer:

to visualize the overview spectrum for a detailed study of the composition of products;
expanding the number of elements to analyze.
