The wording of the method was made in accordance with GOST 8.010-99. The method of determination of moisture in N-methylpyrrolidone was certified. A state standard sample of the following composition: was developed and made thiophene in benzol (DSZU) with a concentration of 0,05 %. The document action was prepared for DSZU with a composition of thiophene in benzol. Branch standard samples (GSZU) were developed and prepared which are required for control of coking products: carbon disulphide in benzol ~ 7.97 %, carbon disulphide in toluene ~ 1.0 % . The sertification analysis of the manufactured standard samples was accomplished. A branch standard sample (GSZU), was developed which is required for control of water and air; iron in sulphuric acid, (C = 1 mg/sm3), rhodanides in water. (C=1 mg/sm3); phenol in ethyl spirit (C=1 mg/sm3). Certificates were compiled for GSZU, as well as instructions for application. Product Description popup.authors popup.nrat_date 2020-04-02 Close
