Substance content

The potentiometry sensor (ion-selective electrode) controls application for determination of polymeric surface-active substances now gets the increasing value. Potentiometry sensor controls are actively used due to simple instmment registration, a wide range of determined concentrations, and opportunity of continuous substances contents definition. That less, the ionometry application for the cation polymeric SAS analysis in a solution is limited by complexity of polycation charge determination and ion-exchanger synthesis. 

First Results The confidence interval from linear regression C1(X) was found to be too large in effect, the plant would have to produce with a 0% tolerance for drug substance content a tolerance of about 1% is considered necessary, cf. Fig. 2.12 and Section 4.24 (Fig. 4.35). 

In the non-recycling system, the pectic substance content of the different samples were very stable (Figure 2a). At the end of the assay the oil-in-water emulsion from the finisher and both aqueous discharges had very similar values of around 0.2 g AGA/L, similar to that reported by Parish e( al. [5] for the aqueous discharge fi"om an orange peel oil recovery system. However, the oil-rich emulsion had higher values (around 4.0 g AGA/L). 

The moist cake of inulin has at this point a dry substance content of 35-40%. It can be purified by dissolving in hot water to a concentration of about 15-18%, treating with carbon, filtering, and allowing to separate again by chilling. 

The relationship between the refractive index and the amount of dry substance content is well known for sucrose and is the basis for the degree Brix (°Brix) scale. It is arbitrarily set such that 1° Brix is equal to a concentration of 1% sucrose. In other words, the °Brix scale indicates the number of grams of sucrose per 100 g of solution. This relationship also holds for a large number of similar substances and finds extensive use in the food industry. For example, a reading of 40° Brix would mean that the sample contained 40 g of solid per 100 g of solution.

The distillate in tower 11 is periodically sampled. At first the analysis is carried out until the density reaches 1.002 g/cm3, after that one determines the main substance content. When the main substance content is at least 93% and that of the head fraction does not exceed 1-2%, the separation of the intermediate fraction is completed. 

The synthesis in reactor 3 is conducted at 120-125 °C and constant agitation for 3-6 hours. After that, the apparatus is cooled down to 25-30 °C and sampled to determined the content of the main substance. If the content of the main substance is below 60%, the reactor is heated again to 120-125 °C, and the reactive mixture is agitated for another 2-4 hours. If the main substance content is 60% or more, the reactive mixture is poured into collector 6.

When 1.5 volumes acetone is added to the trichloroacetic acid filtrate of the gastric juice, an abundant flocculent precipitate forms, which contains all the components of dissolved mucin with the exception of soluble mucus. If this precipitate is taken up in dilute alkali and then acidified with dilute HCl down to pH 3.5, a fine flocculent precipitate forms, which we named dissolved mucoprotein (G27, G36). It was later renamed glandular mucoprotein (G9, G38) because of its close relationship to the fundic glands of the stomach. This material contained much protein its nitrogen content was 12.61 0.44% and its tyrosine content 7.50 0.65% by the Folin-Giocalteu reaction. The reducing substance content was 6.38 1.48% before and 12.5% after hydrolysis (G9, G27, G36) (see Table 4). Werner (W9) determined the composition of this mucoprotein fraction and found that it contained 11.2% N by Kjeldahl, 8.8% hexosamine, 4.8% uronic acid, and 2.0% sialic acid. 

However, in order to re-employ these urban sludges in agriculture, it is necessary to know both their hazardous substances content and their related behaviour in the environment.

Stream humic substances are well known for their general resistance to both microbiological and chemical breakdown (Waksman, 1938 Shapiro, 1957 Midwood and Felbeck, 1968). The humic substances content of natural samples containing bacteria and fungi in excess of 10 organisms per milliliter of water has been observed to be essentially constant for months. BOD values are typically near zero (Black and Christman, 1963a Gjessing, 1976 Beck et...
