WebTable 2 shows solvent UV Cut-Off values for some common HPLC solvents and additives. UV cut off is defined as the wavelength at which the pure component has an absorbance of 1Absorbance Unit (AU) in a 1 cm pathlength cell with water as reference. Solvent / Additive: UV-Cut off (nm) WebThe cut-off wavelength distribution diagram of each mode of the circular waveguide is shown in the figure. When the waveguide radius a is constant, the order of the modes remains unchanged. There are many propagation modes in a circular waveguide, the main mode is TE11 mode, and its single-mode operating area is 2.6127a<3.4126a, so the ...
