Internal standard is primarily used to increase the accuracy and precision of analytical methods that have large inherent variability. The method is used in chromatography (GC, HPLC) where a compound similar to the analyte of interest is added to the sample and run. By having the analyte and the standard elute in the same run, the run to run variability is eliminated giving more precise results. Obviously one needs to calibrate the responses of the internal standard with that of the analyte. Incidental benefits are saving time and money by having less runs.
Hope this is useful.

An internal standard is sometimes called a
surrogate when it is added at the beginning of the sample preparation process.
n nHexokinase: Its function is to make sure there is enough glc for the tissues, even in the presence of low blood glc concentrations, by phosphorylating all the glc concentration gradient between the blood and the intracellular environment. n nGlucokinase: Its function is to remove glc from the blood following a meal. n n(Hexokinase, Phosphofructokinase and pyruvate kinase, are 3 regulatory enzymes of glycolysis.) nLiver has an additional enzyme, glucokinase, that phosphorylate only glc n n1. Glucokinase has a high Km because it phosphorylates glc only when its concentration is high. This occurs during the brief period after consumption of a carbohydrate rich meal, when high glc are delivered by portal vein. n n2. Glucokinase has a high Vmax, allowing the liver to remove effectively this flood of glc from the portal blood. So this prevents extreme hyperglycemia after meals. n
Analytically GLC is the best (Gas chromatography)In a productive way distillation is prominent.
Gas-liquid chromatography (GLC), or simply gas chromatography (GC), is a common type of chromatography used in organic chemistry for separating and analyzing compounds that can be vaporized without decomposition.

The concentration of gaseous pollutants is higher nearer their source than at a distance. This change in concentration is the basis for calculating the ground level concentration (glc) of pollutants when designing industrial stacks. In the case of carbon dioxide the gas originates from the industrial combustion of fuel and would be expected to be higher downwind of the source. The same logic applies to sites downwind of busy cities or roadways. The concentration eventually levels out to the approximate 380 ppm typical of the Earth's atmosphere. Interestingly there is a corresponding dip in the concentration downwind o growing crops or forests as the plants extract the carbon dioxide and replace it with oxygen.

Mazda very cleverly came up with the catchy "GLC" designation to shorten the moniker "Great Little Car". In my opinion, Mazda makes several "great little cars", and it's a shame so many people have forgotten what "GLC" stands for.

GLC has a stationary liquid phase and gas moving phase HPLC had a stationary solid phase and liquid moving phase HPLC is done under high pressure. HPLC can be used for thermally unstable compounds as opposed to GLC HPLC can be used for polar or low volatile compounds as opposed to GLC
