SU95835A1 - The method of introducing the substance investigated by spectral analysis into the zone of burning of an electric arc - Google Patents

Description

The accuracy of a single localized analysis in a large section depends on the way it is used to “follow the material into the zone” at the burning of an electric arc. It was necessary for the FEL and its injection into arcs to exclude the effects of freeze evaporation, and the amount of evaporated material did not necessarily exist. In the process of photogenerating the spectrum. POMi-mo eto.go it is desirable that e, ko, the growth of ioparani should go to Hornu.l1I: r (Vke "all isnipiHiHoe veli1e: tv: o pop gave in duPovoy between ducks.

PisiBecTHo is a large amount of method for introducing ls-ss; 1 unit, of the substance, or the so-called sample, into the area of the arc, but most of them do not provide high accuracy due to non-observance of the listed conditions.

A typical example of this is the best paicnpOCTpaHeiHiHHii method of paralleling a sample of the recess in one OF the electrodes. С41ешИ1ва1Н1ие Samples with graphite (the powder has not weakened enough: the influence of the cancer is not enough). The amount of material to be evaporated varies in

During the shooting process, the call-wah change in y-. aroused.

Regulate the speed of the power supply; in the case of sroM, you can only roughly, change the value of the field “: a and electric power.

The method of evaporation with the help of h1n1c.os, teN; Noah coal tubes (solsMYKI) although n satisfies the following conditions. but it requires a great deal of attention and tp1-ability to work.

I edited the method of "introducing WEP |, is long" and is deprived of the indicated incomplete B and the body differs, that the investigated M-material that has been repressed with some kind of heat-resistant rod, BB01ДЯТ through kalalitovito A nylon electrode into the arc space at the One-Time-Along Process, and this channel flows to whom: -: gabo a suitable gas. This achieves the following: elimination of the influence of evaporation fractions; BbiHOiC napOiB, formed in the electrically electrically | kagnale | yes, in the Zon of arcing; iados, the rate of evaporation of dissolvable material only from cKopiOCTM re-displacement.

The drawing shows a device for the implementation of the proposed introduction slots for the material under study in the ash of the electric arc.

 For the stabilized cKopODTb 1IS1 vapor equilibrium, it is determined by the speed of movement of the rod.
