ADVANTAGES OF X-RAY SPECTROMETER XFA-200

THE NEW LOW DETECTION LIMITS FOR EDXF ANALYSIS OF SOLUTIONS WITH THE USE OF POLYCAPILLARY CHEMICAL SENSORS

Energy dispersive X-ray fluorescence analysis is widely accepted as a method for determination of metals and other components in solutions with medium and relatively high concentrations of target elements. The detection limits of standard EDXF technique are around tens ppm.

A combination of EDXF analyzer with chemical sensors mounted in streams to be analyzed is the fresh approach of the Institute for Roentgen Optics to resolve these problems. “XFA-200" "SENSOR” has the detection limits from hundreds to tens ppb for various metals in solutions.

APPLICATION AREAS OF THE X-RAY SPECTROMETER ANALYZER

- Water preparing for power plants

- Control of waste waters for industrial and agricultural plants

- In-line and On-line control of technological processes for chemical industry, hydrometallurgy, galvanic production, pharmaceutics, food production and many more

- Criminalities

- Scientific investigations

THE TECHNOLOGY OF THE X-RAY SPECTROMETER SENSOR XFA-200

New types of multi-use chemical sensors and sensor-based XF analytical instruments are elaborated at the Institute for Roentgen Optics. The sensors are made using polycapillary tubes or plates consisting of hundred thousands micro-channels, each containing a micro-grain of sorbent. The population of micro-grains is arranged and entrapped at one of the ends of the polycapillary tube to form a sorption single layer, which is active to mass-exchange with the analyte. The choice of sorbents is determined only by the type of elements or substances to be detected. The related XF instrument is very simple and consists of collecting and measuring chambers. The first one can be of remote type; the stream of analyte is passed through it.
