The key difference between calibration curve absorbance and concentration is that calibration curve is a graph of absorbance and concentration, absorbance is the amount of light absorbed by a sample whereas concentration is the amount of a substance distributed in a unit volume. Spectroscopy is an analytical technique which is useful in determining the concentration […]

The key difference between volumetric and gravimetric analysis is that the volumetric analysis measures the quantity of an analyte using volume whereas the gravimetric analysis measures the quantity of an analyte using weight. In an analysis, we measure the amount of an unknown compound with the use of a known amount of a known compound. […]

The key difference between gravimetric and volumetric feeder is that we measure the rate of a gravimetric feeder in the unit of volume per unit time whereas we measure the rate of a volumetric feeder in the unit of weight per unit time. Feeders are useful to handle bulk solids. There are two forms of […]

The key difference between primary and secondary standard solution is that primary standard solution has a high purity and less reactivity whereas secondary solution has a less purity and high reactivity. Standardization is the process of finding the exact concentration of a prepared solution using a standard solution as the reference. Standard solutions have accurately known […]

The key difference between dewpoint and wet bulb temperature is that dewpoint temperature is the temperature to which we should cool the air to saturate the air with water vapor whereas wet bulb temperature is the temperature that we get from a moistened thermometer bulb that is exposed to air flow. Dew point and wet […]

The key difference between natural and forced convection is that in natural convection, the motion of the fluid is influenced by natural means whereas, in forced convection, the motion of fluids is influenced by external means. The difference between natural and forced convection related to heat transfer is that there are no external factors affecting […]

The key difference between uniaxial and biaxial crystals is that uniaxial crystals have a single optic axis whereas biaxial crystals have two optic axes. The optic axis of a crystal is the direction that the light propagates through the crystal without facing double refraction. All the light waves that are parallel to this axis do […]

The key difference between cuvette and test tube is that the cuvette has two straight sides whereas the test tube has no straight sides. Further, cuvettes and test tubes have different applications and chemical compositions as well. Both cuvette and test tube have common use in analytical chemistry as equipments for analysis. Both these are […]

The key difference between optical density and absorbance is that the optical density measurement takes both, the absorption and scattering of light, into consideration whereas absorbance measurement takes only the absorption of light into consideration. Both optical density and absorbance are related terms. Optical density (OD) is the degree to which a refractive medium retards […]

The key difference between single beam and double beam spectrophotometer is that in single beam spectrophotometer, all the light waves pass through the sample whereas, in double beam spectrophotometer, the light beam splits into two parts and only one part passes through the sample. Spectrophotometers are analytical instruments used to quantify the analytes in a […]
