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.

With volatile liquids or gases these numbers seem to be lower.

If 1000. ml of linseed oil has a mass of 929 g, calculate the density of linseed oil
Ierofanga [76]
<span>0.929 g/ml Density in this case is defined as mass per volume. Or in other words, mass divided by volume. So you simply divide 929 grams by 1000 ml. Giving 929 g / 1000 ml = 929/1000 g/ml = 0.929 g/ml</span>
