Our Analyzer is a special highly sensitive magnetic mass spectrometer tuned to record hydrogen, and provided with a digital recording system for mathematical processing of measurement results, and with an extraction/loading assembly for high-temperature recovery of hydrogen from aluminum samples.
The operating principle of the instrument is based on measuring of the quantity of hydrogen escaping from a sample weighing 0.2-7 g when heated to a temperature close to the melting point (vacuum heating), or when melted in vacuum (vacuum melting).
Due to a special design, the sensitivity of our analyzer is one thousand times higher than with standard mass spectrometers.
The high sensitivity enables hydrogen concentration testing in samples weighing 200 mg or less. Surface hydrogen may be precisely isolated from the general mass on the monitor screen.
The AV-1 enables analyzing hydrogen concentrations in any aluminum alloys (containing Li, Mg, Sr, Pb, etc.).
The experience of the instrument operation for 20 months at KUMZ aluminium factory in Kamensk-Uralsky and at VILS (Central Institute for Light Alloys) in Moscow confirms a good recurrence rate of analysis results. According to VILS conclusion, AV-1 fully complies with GOST 21132.1-98.
The calibration device developed by us allows to greatly reduce the consumption of standard samples.
While the performances of AV-1 are higher, its price is lower than that of other known hydrogen analyzers.
As a high-sensitivity analyzer, the instrument may be used to test the hydrogen content in gaseous, liquid, and solid matter. So if there are unsolved problems with H-testing, or there is need in high-precision measurings, contact the creators of AV-1.
The analyzer is designed for continuous round-the-clock operation, and may be used as a high-sensitivity sensor to test the gaseous hydrogen content in metallurgy and in the electronic industry, in hydrogen generator maintenance, and for hydrogen leak detection in the chemical, food, oil refining, motor, and aerospace industries.
