| Abstract: | Conclusions An advantage of the FS-112 type of analyzer as compared with other domestic instruments is the possibility of determining gel-particles and mechanical contaminants contained in a viscose, and of determining their disperse composition in five measurement ranges — from 5 to 500 µ.The use of this instrument permits one to investigate viscose quality in more detail, and to select filtration conditions appropriately.The procedure developed has good reproducibility and can be recommended for introduction in laboratory practice and manufacturing conditions instead of the  Tsellosko-202 counter.It is inadvisable to carry out the determination of the content of gel-particles and other inclusions by the procedure described on unfiltered viscoses, since these viscoses contain much fibre and film, which may choke the instrument capillary.Translated from Khimicheskie Volokna, No. 5, pp. 38–40, September–October, 1987. |
