ISTRAN was founded in 1995 to develop and produce chemical analysers
for laboratories and outdoor applications as well as for on-line
monitoring of waters and technological liquids.
The analysers of ISTRAN have found numerous applications in
environmental analysis, food chemistry, process analysis
(microelectronics, chemistry, metallurgy, water resources, etc.).
Some typical applications involve the determination of
metals, semi-metals such as As, Ag, Bi, Cd, Cu, Cr, Fe, Hg, Mn, Pb, Sb,
Se, Sn, Tl, Zn, etc., in an extremely wide concentration range
beginning at the low ppb (ug/l)levels. Moreover, the systems enable the
measurement of some non-metals such as chlorides, bromides, iodides,
sulphides, sulphites, ammonia, phosphates, acids, bases, EDTA, etc.
Most applications make use of flow-through electrochemical
coulometry and in-electrode coulometric titrations - methods developed
or improved by ISTRAN in cooperation with Slovak, Czech and German
universities.
Some unique applications:
- Direct determination of total arsenic in various types of samples, such as waters, technological liquids, foods.
- Calibrationless (absolute) analysis of trace concentrations of heavy metals (Hg, As, Se, Zn, Cd, Pb, Cu, Mn).
- Unattended and simultaneous monitoring of trace concentrations of some species in complex matrices.
- Measurement of trace concentrations of arsenic in concentrated cadmium solutions.
- On-line simultaneous monitoring of tin and lead in waste waters.
- Fast determination of iodides in salts, food additives, beverages, foods and urine.
- Measurement of oxide layers on tin coated steel sheets.
- Simple
and fast determination of ascorbic acid (C vitamin) in beverages,
vegetables, fruits, milk powder, etc., by means of a portable
coulometric analyser PCA.
