- Country of manufactureRussia
Is new model of devices of the TA series, including TA-4, TA-07 analyzers. Characterize ample analytical opportunities of a method which without conceding on sensitivity to expensive spectral and atomnoabsobtsilnny methods much cheaper them is simpler and more economic in operation.
Opportunities
The defined elements | The analyzed objects |
Zn, Cd, Pb, Cu, Hg, As, Fe, Se, Sb, Sn, Cr, Bi, Mn, Co, Ni, Au, Ag, Pt, Pd, Os, iodine, aniline, B1, B2, C vitamins and other impurity | natural, drinking, mineral and drain waters; air of a working zone and atmospheric; alcoholic and soft drinks; milk and dairy products; grain, grain, flour, coffee, cocoa, meat, fish and products of their processing; salt, sugar, stern, agricultural products, dietary supplements, cosmetics; children's toys; ware. |
Design features and advantages:
a) High efficiency and stability of hashing of the analyzed solution at the same time in three cells at incommensurably simpler construction, than the rotating disk electrode with one cell (it is reached due to vibration of an indicator electrode at a resonance frequency).
b) Simultaneous analysis of 3 tests
c) Simultaneous definition of Zn, Cd, Pb, Cu (items and would also increase productivity of analyses)
d) Combination in one device of UF-radiation and ozonization.
Allows:
– analyze the natural and purified drain waters without evaporation and ashing;
– increase sensitivity and reliability of analyses due to deactivation in a cell
and on an indicator electrode stirring the analysis organic chemistry and oxygen;
– transfer the defined elements to electrochemical active form.
e) Functionality due to implementation of a highly sensitive hronoamperometriya according to the patent No. 231452 is expanded;
e) Reliability and stability of vibration of an electrode is increased. It allowed to increase, in particular, the accuracy and convergence of results the analysis, to facilitate procedure of periodic checking of the analyzer, and also to lower own instrumental error to 15% to iuvelichit number of the normalized metrological characteristics from the 4th to 7;
g) The normalized metrological characteristics of mg/dm3
The defined concentration and errors:
Zinc, lead, copper (II): From 0,0001 to 1,0 on. |
± 20% |
Cadmium (the instrumental error is lowered): From 0,0001 to 0,001 on. |
± 20% |
From 0,001 to 1,0 on. | ± 15% |
Mercury (I) From 0,00005 to 0,01 on. |
± 20% |
Arsenic (III) From 0,001 to 0,5 on |
± 20% |
Gland (III) (sensitivity of the device much is increased) From 0,002 to 0,01 on |
± 45% |
From 0,01 to 1,0 on. | ± 20% |
The minimum defined concentration | 0,00005 |
Rationing of the device on mercury, arsenic and iron, and also higher sensitivity on gland and lower values of errors is increased by reliability and accuracy of analyses.
h) Two-level vertically rotary raising of electrodes from cells (allows to use more sensitive extended electrodes (not less than 65 mm), and also does without protective covers on the electrodes which are becoming soiled in use and, thereby, complicating the analysis).
j) High-strength, chemically resistant case from composition AVS of plastic of production Germany
k) It is reduced UF-irradiator capacities to 11 W (one lamp of 11 W. The security level of ozonization of air is provided and the temperature error of the analysis decreases).
l) Wireless connection of the analyzer to the computer through Bluetooth (convenience in work and mobility is provided)
m) Implementable methods:
– Voltammetry
– Hronoamperometriya with vibration of a working electrode (according to the patent No. 231452)
Mass of the analyzer, no more than 3,5 kg.
Overall dimensions, no more than 300 x 275 x 130 mm
Average term of service not less than 8 years.
Intertesting interval of 2 years.
The analyzer is delivered complete with the branded software and techniques of KHA.
On the device voltamperometrichesky and hronoamperometrichesky techniques of other developers can be also implemented.
In general, methodical providing makes more than 50 techniques of KHA.
