WebThe presence of impurities in a solid sample will tend to cause the melting point range to be low and broad. If a sample is not finely pulverized, there will be air spaces between the particles when the sample is loaded into the capillary tube. This will cause the melting point to be higher and broader than normal. WebOct 23, 2024 · Why should a melting point determination sample never be reused? If a MP must be redetermined always use a fresh sample – once a sample has melted, you …
