7.2.2. Preparation of Samples. To obtain the best results the samples under melt should be perfectly dry. Drying is best accomplished by storing the samples in vacuum desiccators over a suitable drying agent such as phosphorus pent oxide. Always dry hygroscopic samples. Provided the sample is dry there is usually little difficulty in introducing a small amount of sample into the capillary tube.
