When conducting a scientific experiment it is necessary to know that you have the correct concentration of the different chemicals involved. It is also important to be able to calculate concentration in order to determine how much of a reactant has been used up in a reaction or how much produ...

A calibration curve usually represents the relationship between concentration and absorbance measurements, but other comparable properties include fluorescence, cell count, PCR product, etc. As soon as the relationship between 2 quantities is directly proportional, it is...
In making a specific galvanic cell, explain how one determines which electrodes and solutions to use in the cell. Explain the effect on the concentration of a solution if it is "over-boiled." How to calculate the concentration on a Beer's law plo...
It is possible to calculate the expected average fragment size for a given genomic DNA if the percent GC content of the DNA and the recognition sequence of the restriction enzyme are known. For example, in a genome with 50% GC content and no dinucleotide bias, a four-cutter can be expecte...
Standard curves are used to determine the concentration of an unknown sample based on a measured response. This article discusses the basics of standard curves, how to test them, and how to calculate concentration from absorbance standard curves.
4.Data processing: The instrument records these reflectances or transmittances and generates spectral data, which can then calculate the color data of the sample (such as CIELAB value). A spectrophotometer works on the principle of measuring light as it passes through or reflects off a sample. ...
For example, the Synopsys REFLET 180S is able to measure BSDF in order to extract/calculate TIS from these measurements. The accuracy depends on the resolution of the measurements. The different angular resolutions of these instruments will allow you to extract the specular part from BSDF ...
Explain how to calculate absorbance change per minute in ONPG enzyme activity. What is the model of enzyme activity that explains how a particular enzyme will only fit with one particular type of substrate? Why might a glucose test strip be used to determine the enzymatic...
