Incubate the bottle at 80-90oC until solvent is completely evaporate and bottle is completely dry. By validating the results of halogen moisture analysis against those from the drying oven, companies can benefit from a convenient and compliant alternative loss on drying solution. Results can be printed out for your lab journal or saved on a USB stick to be saved electronically. This means the samples are at the same temperature as the drying oven. 4. During heating, do not cover the lid. A METTLER TOLEDO instrument provides comparable and traceable results in less than 15 minutes. There are many stages of the production process where moisture determination benefits the overall quality of the finished product: raw materials, goods-in, storage, in process control, QC, packaging, etc. Dry the empty dish and lid in the oven at 105C for 3 h and transfer to desiccator to cool. 3. The Oven dry method is widely used for the determination of water content. /XObject << >> Contact us if you don't find what you need. . An alternative thermogravimetric procedure that provides comparable results to the drying oven in a considerably faster time is conducting loss on drying (LOD) with a moisture analyzer. Prepare a tube containing the above chemical except sample as blank. Different industries use different units e.g. 5. Heat insulated pad should always be used. After drying, transfer . It is not applicable to samples containing water-miscible volatile substances or to samples containing added monoglycerides. This method determines moisture content in flour, grain, and various food and feed products by using a simple, acceptable formula. Most substances have an optimum moisture content for obtaining the best possible processing results and therefore attaining maximum quality. %%EOF Dry the empty dish and lid in the ov, Views 1,673 So, moisture content can be determined as: Moisture content = [(W2 W3) / (W3 W1)] * 100. Fill petroleum ether about 250 ml into the bottle and take it on the heating mantle. Dry for 3 h at 105C. hb```5@(AcWe& ~?P#n Tsw`XKiPQD^-9Np1QT The method closely agrees with oven methods established for the same commodities under official U.S. Standards. Determination of Moisture Content_A Complete Procedure (AOAC - YouTube It is also applicable to flour mixes containing NaHCO(3) and yeast foods. endobj Manufacturers of these instruments will furnish conversion tables for their use, but instruments should be calibrated under conditions of actual use in comparison with oven methods. The chemical reaction of water with a Karl Fischer reagent (containing Iodine and Sulphur Dioxide) is monitored with a polarized sensor to determine the water content. The method also describes a standardization procedure for a forced-air oven. How to Ensure Reliable Moisture Analysis Results. ATRO moisture (AM) is the amount of moisture in the sample given as a percentage of the sample's final (dry) weight. After calculating the moisture content of each sample, we also have to find the average value to get the accurate value of moisture content. 141 You can do this either through the ID management functionality on our moisture analyzers or in the differential weighing application on our balances. endobj Dry for 3 h at 105 C. METTLER TOLEDO is an expert in moisture analysis and offers a wide range of reliable and easy to use moisture analyzers to suit the needs of quality control, production and in-process control of many industries, such as pharma, plastics and the food industry. In general there are two ways to find a suitable LOD method for your sample. /Resources << Other attributes and requirements are also covered. Determine lipid content gravimetrically by measuring triplicate aliquots of the chloroform layer into tared containers, evaporate the solvent and weigh. endstream endobj 554 0 obj <. Everything which evaporates upon heating is named moisture. /Length 1396 The moisture content percentage is determined from the difference in weight before and after drying. . 2. 3. NIR has been applied to moisture content analysis of a wide variety of food commodities and is an official method for moisture content determination in dried vegetables (AOAC Method 967.19). Over 6500 samples of cheese were analyzed in an effort to modify the current AOAC procedure. %PDF-1.5 % Note: Ash content of this milk sample could be determined by placing the milk sample, dried at 100C for 3 h, in a muffle furnace at 550C for 18-24 h. Place the dish with sample in the oven. Determination of Moisture Content is the most important proximate analysis. METHOD II-RAPID OR ROUTINE METHOD Use of a barcode reader is fully supported by the differential weighing application on the balance and by LabX. << There is no one-size-fits-all method for moisture content . Weigh about 3 g of sample to the dish.
