Water is present in most naturally occurring soils and has a profound effect in soil behaviour. By Derek Duncan Pharmaceutical Technology 3. Karl Fischer Titration and Loss–on-Drying are the two most widely used methods in pharma — but both techniques have their limitations. It is also used as a subsidiary to almost all other field and laboratory tests of soil. The moisture content of a piece of timber is something many of us take for granted. Whilst no attempt is made to give a comprehensive review of methods of moisture content determination, the principles of the various methods used are discussed and the importance of the relationship between the moisture content of a product and its storage potential is stressed. Residual product moisture content is critical when considering the stability, shelf life and storage temperature of lyophilised pharmaceutical product. AQUAMETRY AQUA- means water METRY- means measurement Aquametry is a quantitative method of determining water content present in a sample. Measuring Moisture Content There are many methods for measuring the moisture content of a pharmaceutical and the method used will depend on the physical and chemical characteristics of the sample. (Wet-base test) or final weight (Dry-base test) and the moisture content calculated. Read this article for different moisture measuring techniques and in what food applications food moisture content is … II.—Errors in the determination by oven drying of known changes in moisture content, Journal of the Science of Food and Agriculture, 10.1002/jsfa.2740110605, 11, 6, (315-319), (2006). T. A. Oxley, S. W. Pixton, Determination of moisture content in cereals. The determination of moisture content by the solvent method was performed in two hours, while at least 24 hours are necessary using the oven method. MOISTURE DETERMINATION TECHNIQUES 1. By far, the most important method for determining the water content of pharmaceuticals is the Karl Fischer titration. Moisture affects the angle of repose, as anyone who has ever built a sand castle can confirm. 3.1 Determination of Moisture Content 3.1.1 General requirements 3.1.1.1 Scope. There are many applications where trace moisture measurements are necessary for manufacturing and process quality assurance. Chemistry. 3.1 Introduction. The Importance of Determining Residual Moisture Levels in Your Freeze Dried Sample . Timber is normally kiln dried down to about 8-10% moisture content but it will quickly reabsorb moisture if it’s stored badly. Water content is determined by the Karl Fischer titration method and it consists of only water i.e moisture content. equilibrium of a product a ‘safe’ storage moisture content can be stipulated. Loss on drying (LOD) is determined by heating the sample below its melting point in an oven and it includes all volatile matter including water content and solvents. The moisture content in the 42 creams were first determined by KF titration procedure in triplicates and were found to be between 60% to 80%. From the moisture content/r.h. The water content of medicaments strongly influences their quality, shelf life and stability as well as the release of the active substances. The determination of water therefore assumes great importance in pharmaceutical analysis. The purpose of this study is to investigate the effects of moisture content on the storage stability of freeze‐dried lipoplex formulations. Headspace Moisture Analysis for Determination of Residual Moisture Content in Lyophilized Pharmaceutical Products Headspace moisture analysis is a rapid non-destructive analytical method that may potentially address the limitations of traditional methods used for residual moisture determination. Increasingly, industry has become driven by more stringent regulations, where companies are asked to understand specific material properties, of intrinsic value during the design and implementation of an efficient lyophilisation recipe. We buy timber from the wood yard and expect it to be fit for purpose. If water is added to particles such as sand, water coating the grains would tend to bind them together by its surface tension, giving rise to greater internal cohesion, and therefore shear strength. Many industries, including the food, chemical, and pharmaceutical product industries, depend heavily on exact knowledge of the moisture content … A calibration and validation set were designed for the conception and evaluation of the method adequacy. Water is found in all food products. Moisture is an important factor in food quality, preservation, and resistance to deterioration. Through the process of dynamic vapor sorption (DVS), the quantitative uptake of moisture can be measured, and the resultant data used to accurately calculate amorphous content. Importance: • Physical properties of a drug or … Drying oven vs. Halogen Moisture Analyzer guide will be of interest to anyone involved in moisture analysis applications in pharmaceutical, chemical, food or other industries, as moisture content affects the quality, shelf-life and usability of a wide array of end products. Water content affects the cohesiveness of particles. Moisture analysis following freeze-drying needs to be fast and accurate, particularly for the often expensive, complex and lengthy procedure of pharma manufacture. Determination of Moisture and Total Solids . Moisture content determination of pharmaceutical pellets by near infrared spectroscopy: Method development and validation From biological research organizations, pharmaceutical manufacturers, to food producers and packers, The national pharmacopoeias describe the Karl Fischer titration as a method for water determination. Automation allows for accurate and highly repeatable water content determination. Indeed, the resulting accuracy profile clearly showed that this model was able to determine moisture content over the range of 1-8% with a very acceptable accuracy. 2. Importance of moisture content determination in pharmaceuticals - 4798522 1. Too little or too much can affect the physical and chemical properties of food, which directly correlate to freshness and shelf-stability. Log in Join now Secondary School. Log in Join now 1. Water content can be determined by any one of the following procedures: Loss on drying, for drugs containing no constituents other than water volatile at 105°C; Water content by Karl Fischer (Titrimetric) Mix and accurately weigh the substance to be tested, and, unless otherwise directed in the individual monograph, conduct the determination on 1 to 2 g. Depending on the balance and heating mechanism, a wide array of precision and accuracy is available. The results do not contain other volatile matter except the water. The aim of the present study was to develop and validate a near infrared method able to accurately determine a moisture content of pharmaceutical pellets ranging from 1% to 8% in order to check their moisture content conformity. Moisture content is one of the most commonly measured properties of food materials. Water determination plays an important role in the pharmaceutical analysis. A knowledge of the moisture content is used as a guide to the classification. amorphous content gravimetrically. Water content is used in a wide range of scientific and technical areas and is expressed as a ratio, which can range from 0 (completely dry) to the value of the materials’ porosity at saturation. Moisture determination is of great importance in the production and use of many substances. As higher moisture content often correlates with poorer stability, this has resulted in recommendations for low residual moisture content of 0.5-3% w/w [4] and moisture induced instability is particularly an issue when preparing primary biological reference materials as these must maintain their potency for the life of the standard [7] although over-drying may also be deleterious to stability. Moisture analysis covers a variety of methods for measuring moisture content in both high level and trace amounts in solids, liquids, or gases. For example, the moisture content can affect the efficiency of achemical reaction or determine the shelf life of pharmaceuticals or foods. The present study confirmed that NIR spectroscopy could be used in the PAT concept as a non-invasive, non-destructive and fast technique for moisture content determination in pharmaceutical pellets. The standard method for moisture determination is Karl Fischer (KF) titration, based on either volumetry or Moisture in percentage amounts is monitored as a specification in commercial food production. Determination of moisture content also is necessary to calculate the content of other food constituents on a uniform basis (i.e., dry weight basis). This video is about the determination of moisture/water contents in the pharmaceuticals by using different methods and apparatus. DC‐Cholesterol: DOPE (dioleoyl phosphatidylethanolamine)/plasmid DNA lipoplexes were prepared at a 3‐to‐2 DC‐Cholesterol + to DNA − molar ratio and lyophilized prior to storing at room temperature, 40, and 60°C for 3 months. The soil moisture content of soil is the quantity of water it contains. In addition, the oven method requires a separate determination of the yield of essential oil for the calculation of the moisture content. Tests can be manually conducted (weigh, oven dry, weigh) or automated (integrated weight and heating unit) with systems called Moisture Determination Balances. Learn how automated water content determination in pharmaceutical manufacturing is possible with volumetric and coloumetric Karl Fisher titration, how the KF oven method excels in cases where direct titration is not possible, and how automated homogenizers enable water determination in tablets.
