| Operative advantages of the analyzer "Ecotest-VA" |
- the possibility to determine simultaneously several elements (zinc, cadmium, lead, copper) from one single sample in a single experiment
- high sensitivity (for example for Cd and Pb down to 0,1ppb or even less)
- the automatic mode of the performance of the measurements and calculations
- low cost of the single determination
- low cost of the equipment and the maintenance of the equipment
- the kit to measure the heavy metals - EURO 1560
- the kit to measure iodine - EURO 1680
- the kit to measure the heavy metals and iodine - EURO 1800
- no need of an over-qualified operator
- no need of compressed gases or hydrogen generators
- simple maintenance: the routine measurements of the heavy metals and iodine can be studied under supervision of our consultants during 2 working days
|
| The certification of analytical procedures: |
- The procedure to measure the contents of iodine in food products and food raw materials (completely without mercury or mercury salts) certified in 2001, allowed for application by the Health Ministry in 2003.
- The analytical procedure to measure the methyl alcohol and diethyleneglycol in the waste water of the gas industry were certified in 2001.
- The analytical procedure to measure selenium in drink water, mineral water, soft drinks was certified in 2005 as the National Standard of Russia. Practically one can readily see selenium in any sea water!
- The analytical procedures to measure Cu, Cd, Zn, Pb, Mn, Bi. Ni, Co in different types of water, soils, food products and the air of the working zone were certified in 2004.
- One can easily adjust the system for analytical procedures of other companies or from literature, because the system is flexible.
