Low molecular weight meaning
WebMolecular Weight Distribution. For GPC analysis, the peak shape is not always sharp (Fig.4). A wide peak width means that the molecular weight distribution of the sample is wide, and a narrow peak width means that the molecular weight distribution is narrow. Each peak contains a mixture of high molecular substances with different molecular … Web4 jun. 2015 · Fluids with molecular weights of less than 43 are generally gases, which include gas condensates, wet gases, and dry gases. A molecular weight of 43 marks the lower molecular-weight limit of volatile oils. Black and volatile oils are sometimes subdivided into different fluid types.
