Screening of oils, fats and oil\/fat-related samples to obtain main (e.g. TAGs) and minor component (e.g. sterols, sterol esters, tocopherols, squalene, wax esters, fatty alcohols, and glycerol) information in one single analysis. For a truly quantitative analysis of pre-identified compound classes specific methods are more appropriate. Beside the (semi-)quantitative determination of the oil\/fat composition mentioned above, the method can also be used as a useful qualitative screening tool for the relative comparison of sample compositions.<\/p>\n<h4>PDF Catalog<\/h4>\n<table border=\"1px\" class=\"des-table\">\n<tr>\n<th>PDF Pages<\/th>\n<th>PDF Title<\/th>\n<\/tr>\n<tr>\n<td><b>2<b><\/td>\n<td>National foreword  <\/td>\n<\/tr>\n<tr>\n<td><b>4<b><\/td>\n<td>European foreword  <\/td>\n<\/tr>\n<tr>\n<td><b>6<b><\/td>\n<td>Foreword  <\/td>\n<\/tr>\n<tr>\n<td><b>7<b><\/td>\n<td>1 Scope <br \/> 2 Normative references <br \/> 3 Terms and definitions <br \/> 4 Principle <br \/> 5 Reagents  <\/td>\n<\/tr>\n<tr>\n<td><b>8<b><\/td>\n<td>6 Apparatus  <\/td>\n<\/tr>\n<tr>\n<td><b>9<b><\/td>\n<td>6.8 Ultrasonic bath. <br \/> 6.9 Nitrogen evaporator. <br \/> 7 Sample <br \/> 7.1 Sampling <br \/> 7.2 Preparation of test sample <br \/> 8 Procedure <br \/> 8.1 Preparation of the internal standard, tridecanoylglycerol (5.2.5),  c  = 20 mg\/ml <br \/> 8.2 Preparation of the individual standard solutions for determination of response factors  <\/td>\n<\/tr>\n<tr>\n<td><b>10<b><\/td>\n<td>8.3 Silylation of the standards <br \/> 8.4 Preparation of the sample <br \/> 8.5 Sample solution <br \/> 8.6 Silylation of the sample <br \/> 8.7 Gas chromatography  <\/td>\n<\/tr>\n<tr>\n<td><b>11<b><\/td>\n<td>8.8 Peak identification and integration <br \/> 9 Result of the determination <br \/> 9.1 Calculation of the response factor  <\/td>\n<\/tr>\n<tr>\n<td><b>12<b><\/td>\n<td>9.2 Quantitative determination <br \/> 10 Precision of the method <br \/> 10.1 Interlaboratory test  <\/td>\n<\/tr>\n<tr>\n<td><b>13<b><\/td>\n<td>10.2 Repeatability <br \/> 10.3 Reproducibility <br \/> 11 Test report  <\/td>\n<\/tr>\n<tr>\n<td><b>14<b><\/td>\n<td>Annex A (informative) Typical chromatograms  <\/td>\n<\/tr>\n<tr>\n<td><b>24<b><\/td>\n<td>Annex B (informative) Results of an interlaboratory test  <\/td>\n<\/tr>\n<tr>\n<td><b>28<b><\/td>\n<td>Bibliography  <\/td>\n<\/tr>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p><b>Animal and vegetable fats and oils.
