Portable X-ray fluorescence analyzer "MetExpert" is used for quantitative analysis of metals and alloys in the range from Na (sodium) to Pu (plutonium)
The analyzer provides operation in a portable or laboratory version of use, powered by a built-in 15V DC battery pack. When working in laboratory conditions, the analyzer is powered from an AC network with a voltage of (220±15) V and a frequency of (50±1) Hz.
Analysis of metals and alloys is carried out without sampling and destruction of the object under study and without vacuuming, ensuring the analysis of materials containing elements from Z=11 (Na) to Z=95 (Am). Before measurement, the analyzed surface of the sample must be cleaned of contaminants and freed from paint and varnish coatings.
The analyzer design allows for measurements of the elemental composition of samples of virtually any shape and size.
Technical characteristics of the MetExpert PRFA Weight: with a large battery and a computer — 2.9 kg. with a small battery without a computer — 2.1 kg. Overall dimensions — 100×260×290 mm. Computer — tablet, with a screen diagonal of 8″ (MetExpert PRFA, 2011 model) Time to establish the operating mode — no more than 5 min. The measurement time is selected by the operator and ranges from 5 s to 300 s (depending on the type of sample or area being analyzed). The time of continuous autonomous operation with a standard set of batteries is at least 8 hours. The equivalent dose rate under normal analyzer operation conditions, at any accessible point at a distance of 0.1 meters from the analyzer surface, is no more than 1.0 μSv/h. Mean time between failures — not less than 2000 h. Service life of Tsl — 8 years. Service life of a small-sized X-ray emitter, ultra-mobile personal computer (UMPC), battery pack and charger is determined by the passport data for these purchased products and is not less than 500 h. In terms of resistance to the effects of temperature and humidity of the ambient air, the analyzer complies with GOST 22261-84, group 4. Operating temperature range from –35°C to +45°C Warranty period of operation — 18 months from the date of commissioning, but not more than 24 months from the date of acceptance of the PRFA by the QC representative. Warranty period of storage — not more than 6 months from the date of manufacture of the analyzer.
