In these equations, the subscript A is for analyte (the solution) and T is for the toluene with the Rayleigh ratio of toluene, R T being 1.35×10 −5 cm −1 for a HeNe laser. As described above, the radius of gyration, R g , and the second virial coefficient, A 2 , are also calculated from this equation.
Hypothetical dynamic light scattering of two samples: Larger particles on the top and smaller particles on the bottom. Dynamic light scattering (DLS) is a technique in physics that can be used to determine the size distribution profile of small particles in suspension or polymers in solution. [1]
Dimethylacetamide (DMAc or DMA) is the organic compound with the formula CH 3 C(O)N(CH 3) 2. This colorless, water-miscible, high-boiling liquid is commonly used as a polar solvent in organic synthesis. DMA is miscible with most other solvents, although it is poorly soluble in aliphatic hydrocarbons.
Democrats are licking their wounds after Vice President Harris’s defeat to President-elect Trump, but already are looking toward who might lead their party in a 2028 presidential contest.
A calibration first consists of a preliminary test in which the fundamental calibration capability is checked. The quartz control plates must meet the required minimum requirements with respect to their dimensions, optical pureness, flatness, parallelism of the faces and optical axis errors.
