Set "Expert - 001A" - amperometric titrator on the basis of the analyzer of Expert - 001 liquid - the new modern device for student's practical works.
The amperometric titrator "the Set "Expert - 001A"" is intended for carrying out amperometric titration, that is titration with definition of point of equivalence in current size through indicator electrode.
The amperometric titrator "the Set "Expert - 001A"" is executed on the basis of the analyzer of Expert - 001 liquid. All main modes: measurement of EMF, rn and ionometrichesky measurements, potentiometric titration, etc. are carried out precisely to compliance with the Operation manual (RE) on the liquid analyzer.
Amperometric titration is carried out in the special mode - "Potentsiostat" (or "amperometric Titrator"). Now the device can manage biamperometrichesky indiktorny electrode, giving on it the set potential and fixing current. Potential can life is set ranging from - 5 V to + 5 Century.

The device consists of the measuring converter of the analyzer of Expert - 001 liquid with the Potentsiostat mode (or "amperometric Titrator") (further - SP), indicator electrode and the service equipment.
1. Expert - 001 analyzer mod.3 - 0.1. with the additional Potentsiostat mode ("amperometric Titrator")
2. Electrode of biaperometricheskiya
3. RITM - 01 magnetic stirrer
4. Electrode support holder
5. Burette of 25 ml
6. Glass jar (2 pieces)
For performance of specific objectives of practical work flexible complete set the service equipment in coordination with the customer.
Note: Amperometric titration call such type of usual titration at which the point of titration is determined by current size through indicator electrode. In the USSR many techniques of amperometric titration have been developed (see, for example, book of O. A. Songin, V. A. Zakharov "Amperometric titration", M, "Chemistry", 1979, 304 pages)
Tasks of amperometric titration are included in programs of workshops practically of all departments of analytical chemistry of the Russian Federation, Ukraine, Belarus and Kazakhstan.
Unfortunately, these tasks have not been provided with any worthy equipment until recently. Installations consisted of set of blocks: potentsiostat, ampermeter, some burettes. All this looked rather poorly and did not add the authority to either teachers, or the studied subject.
By the time of when you read these lines, on new installation have already successfully passed practical task "Amperometric definition of zinc by titration by potassium hexacyanoferrate" about 200 students of the Russian State university of oil and gas of I. M. Gubkin.
