The key difference between bulk density and specific gravity is that bulk density is a direct measurement, whereas specific gravity is a relative value. Density is the mass per unit volume of a substance. Specific gravity or relative density is the ratio between the density of a substance to the density of a given references […]

The key difference between Zeeman effect and Paschen Back effect is that Zeeman effect involves a small splitting compared to the energy difference between the unperturbed levels, whereas Paschen-Back effect involves the presence of an external magnetic field in which the energy levels of the atoms are split. Zeeman effect and Paschen-Back effect are important […]

The key difference between cation exchange capacity and anion exchange capacity is that cation exchange capacity shows the quantity of negative charge available to attract cations, whereas anion exchange capacity shows the positive charge that is available to attract anions in a solution. Resins are important substances in the field of analytical chemistry. There are […]

The key difference between diffraction grating and transmission grating is that diffraction gratings can separate polychromatic light into its constituent wavelengths, whereas transmission gratings are a type of diffraction gratings that involves diffraction of light in different angles to give a diffraction pattern. There are four major types of diffraction gratings. These include ruled gratings, […]

The key difference between spectrophotometer and spectrofluorometer is that spectrophotometer involves the measurement of absorption, whereas spectrofluorometer involves the transition of polyatomic fluorescent molecules from their higher energy level to a ground state by lowering their energy level through emission of photons. A spectrophotometer is an analytical instrument that can measure the concentration of a […]

The key difference between absorbance and fluorescence is that we can use an absorbance analysis technique to directly measure the amount of a specific wavelength that is absorbed by a sample without dilution or assay preparation, whereas fluorescence analysis requires sample preparation in which sample of interest must be bound with the fluorescent reagents in […]

The key difference between Buchner and Hirsch funnel is that Buchner funnel is used to collect a desired solid from a liquid by vacuum filtration method, whereas Hirsch funnel is a smaller Buchner funnel used to separate a solid from a small volume of liquid. Buchner funnel and Hirsch funnel are important analytical instruments we […]

The key difference between molecular distillation and short path distillation is that molecular distillation uses extremely low vacuum pressure and it is a type of short path distillation technique, whereas short path distillation is an analytical technique and a type of distillation that allows the sample to travel a short distance at reduced pressure. Molecular […]

The key difference between volumetric and serological pipettes is that volumetric pipettes are calibrated to deliver a certain volume of a solution through free drainage, whereas serological pipettes are calibrated all the way to the tip, and the last drop of the solution has to be blown out. Pipettes are very important and regularly used […]
