Of X-ray Measuring Complex RIKOR

This small-size desktop

multi-functional X-ray diffractometer "RIKOR-2"

is designed for phase and spectral express analysis of powder samples

The X-ray diffractometer "RIKOR-2" is certified with the Federal Agency for Technical Regulation & Metrology (Certificate RU.C.38.002.A №23217) as measuring tool type, registered with the State Registry of Measuring Tools under №31025-06, and allowed for application in the Russian Federation

The X-ray diffractometer "RIKOR-2" (XRD/XRF DT) is a new generation of desktop x-ray diffractometers developed by IRO specialists. The main advantage compared to other companies manufacturing similar equipments is that we not only manufacture x-ray diffractometers but use them for control checks in various industries. This ensures continuous feedback from customers, thus, allowing fast making modifications in the instruments’ design with regard to customers’ needs.

· It implements the Debye-Sherrer scheme based on parallel x-ray beam.

· It utilized Kumakhov polycapillary optics to create parallel primary beam and collimate the reflected diffracted beam.

· The combination of diffraction and spectrometry channels ideally suits the purposes of on-line monitoring of technological processes.

· Time of analysis – 200 sec.

Application of Kumakhov polycapillary lenses and half-lenses enables high-efficient transportation of x-ray radiation with higher density both for parallel and focused x-ray beams as required for the geometric shape (a line, a dot) without diaphragms. Kumakhov polycapillary half-lens allows creating a spatially collimated x-ray beam with divergence of ~10^-3 rad., which significantly improves the accuracy of determining the position of the diffraction line maximum. Fast replacement of tube within 2-3 minutes is provided for this x-ray diffractometer.

· Automatic insertion into the measurement zone of the spectrometry channel to determine the element composition of sample

· Patented position-sensitive detectors

· High-speed, stability, wide angular range of simultaneous registration

· Application of two position-sensitive detectors to improve resolution

· Automatic switch of detector

· Application of a polycapillary collimation system in front of detector for the resolution purposes

· Automatic setting to a required angle of measurement

· Low level of degradation in the course of operation

· Sealed detectors don't need application of a special gas unit

· Simple replacement of samples

· Horizontal placement of sample

In this X-ray diffractometer "RIKOR-2" X-ray tube of up to 50W power (does not need water cooling) is equipped with Kumahov polycapillary optics used as a collimator. Low-power radiation and strict collimation of the primary beam ensure radiation safety. The x-ray diffractometer "RIKOR-2" dimensions (380x600x600) and a special enclosure allow placing it close to the process line, in unequipped non-special quarters. Instrument operation does not require elaborated sample preparation.

The x-ray diffractometer "RIKOR-2" is equipped with a high-efficacy diffracted x-rays registration unit for registering x-ray diffraction radiation, consisting of a position-sensitive detector and a polycapillary collimating system. Application of a polycapillary filtering unit improves resolution of adjacent peaks, provides filtration of К_β line, improves the peak –to-noise ratio, raises accuracy of determining the angular position of the diffraction peak.
