Some analytes must be derivatized to increase their column retention or detectability. Derivatization means Group of answer choi
posledela

Derivatization means adding fluorescent labels or combining the analyte with chiral reagents or other chemicals to increase detectability.

Some analytes must be derivatized to increase their column retention or detectability.

Retention time can be referred to as the amount of time a solute spends in the stationary and mobile phases of a column.

Detectability is the ability of an analyte to get detected in the mobile phase of chromatography.

The refractometer, fluorescence detector, and UV detector are the three most popular liquid chromatography detectors. These detectors increase the detectability.

For derivatization, the fluorescence detector are used.

Table salt conducts electricity in water, but sugar does not. Explain why?
galben [10]

Answer:

Because sugar has no ions in the solution

Explanation:

Pure water contains very few ions, so it does not conduct electricity very well. When table salt is dissolved in water, the solution conducts very well, because the solution contains ions. When sugar is dissolved in water, the solution does not conduct electricity, because there are no ions in the solution.

In basic words the more ions in the solution there is a better chance to conduct electricity.
