as a function of retention volume, where φ is the polymer concentration, η is the solution viscosity, and ηo is the solvent viscosity. Assuming that the retention volume depends uniquely on Vh, regardless of the chemical structure, the distribution in M may be calculated from the relationship...

Typical distribution of molecular weights in polymers produced by free radical polymerization. The first is a simple average where each molecule contributes equally to the average (a number average molecular weight depicted as M¯n). Let Ni equal the number of the molecules (or moles or other ...
Orbitrap mass analyzer: The Orbitrap mass analyzer offers unprecedented high resolution accurate mass (HRAM) analysis of ions as a function of their rotational frequencies; these data are converted to mass spectra using fast Fourier tran...
How many copper atoms are in a pure copper statue with a mass of 144 kg? Moles: The concept of the mole is very helpful to chemists as it allows them to convert masses of substance into the amount molecules of that substance and thereby conduct more balanced reactions....
At what temperature will the rms speed of molecules of gas become two times of its value at 0 deg C?What is the rms speed of the molecules in low-density nitrogen gas at 0 degree Celsius? (The mass of a nitrogen molecule, N_2, is...
The meaning of MOLECULAR MASS is the mass of a molecule that is equal to the sum of the masses of all the atoms contained in the molecule.
We report here that the potent HNF4α agonist N-trans-caffeoyltyramine (NCT) promotes weight loss by inducing an increase in mitochondrial mass and function, including fatty acid oxidation. Previously, we found in a short term trial in obese mice that NC
Ions may also be produced by removal of one or more electrons from a molecule using electron ionization (EI). This ionization method is historically the dominant ionization method used in MS (most commonly in gas chromatography–mass spectrometry [GC-MS] instruments) and is still used in some ...
