Determination of moisture content is described in Section 8, ANALYTICAL PROCEDURES, ETC", where are listed numerous US Military Specifications. These specs contain also a brief description of required physical tests. Before describing the specification requirement tests, a resume is given of "Measuring Techniques" of fuze explosive components, as discussed in NOLTR 1111(1952), pp 9-1 to 9-56 (Ref 11) The mea surement of fuze component performance consists mainly of a determination of (a) the input characteristics, and (b) the output characteristics...

One of the most successful early measurements was the use of microwave interrogation for the determination of moisture content of foods and materials. An issue of the Journal of Microwave Power was dedicated to the subject of microwave aquametry and contains an extensive bibliography on the subject from 1955 through 1979 (JMP 1980). A more recent compilation has been edited by Kraszewski (1994). [Pg.223]

Once the soil has been sieved, as much plant and animal residues must be removed as possible. This is best done with a pair of forceps, one small portion of soil at a time. The bulk soil should be covered to prevent any further drying. When the soil has been picked over, subsamples can be taken for determination of moisture content and water-holding capacity (WHC see following section) the soil should be stored at 4°C until use. It is advisable to use the soil as quickly as possible, and if storage is unavoidable, it should not normally exceed 3 months. [Pg.252]

This method is used for the determination of moisture content of small grain or finely divided cannon propellant. It is based on distillation of the moisture with a solvent that is immiscible with and heavier than water. Trichloroethylene is the preferred solvent, but carbon tetrachloride is also satisfactory. This method is not suitable for pioplnts containing less than 0.2% moisture. The presence of hydrated compds may cause high results. The presence of finely divided aluminum may cause a reaction with the chlorinated solvent and, in such cases, tests should be made to demonstrate compatability of proplnt and solvent... [Pg.44]

The methods for moisture determination in USP 24/NF 19 are at best, classical, addressing only the determination of moisture content. The specifications for most official articles are arbitrary and may be excessively restrictive or broad. They are not supported by the type of data referred to previously that relate moisture content to the stability or performance of the article. [Pg.2368]

In all the previous examples, the process was absorption, and water ultimately had access to the entire solid variations in particle size, and consequently, surface area, would not effect the profile. In many of the subsequent examples, not only is surface area a determinant of moisture content, but perturbation of the solid can occur during sorption to produce unexpected and dramatic effects. [Pg.2371]

An equally important consideration is the fact that these stresses are different than those that may be responsible for moisture release during manufacturing or within the product after manufacture. One should approach the determination of moisture content with the disconcerting realization that different methods can produce different results and that none of these results may be relevant. [Pg.2374]

The principal advantage of the thermal methods is convenience however, these analyses are not specific for water, and exposure to high temperature may be an unrealistic stress or alter the sample. An acceptable determination of moisture content using a thermal method provides a result with minimal residual moisture... [Pg.2376]

In its simplest form, the Karl Fisher titration is a one-point determination of moisture content. The principal advantage is specificity for water. It is also a non-thermal method, which is very sensitive and can be easily automated. The main disadvantage is that the solid must dissolve in the titration medium to be sure that the total amount of moisture is released. If the analysis is carefully designed in such a way that moisture is extracted from the solid to the same degree each time, accurate and reproducible results can be obtained for solids that do not dissolve.

In Norway, Wieders Farmasoytiske A/S received approval for the use of NIR as an alternative method for identification, assay, and determination of moisture content of paracetamol (acetaminophen) tablets. The Norwegian Medicines Control Authority approved the method in December 1996. [Pg.3632]
