What is the approximate volume injected into a GC? 10-50 μL 500-1000 μL 1-10 μL 100-500 μL 50-100 μL What technique is used to adjust for injection volume inaccuracy? Standard Addition Nothing, the syringe is accurate External Standard Standardization Internal Standard

1-10 μL

Explanation:

Gas Chromatography (GC) is a method of separating the constituents of a complex mixture by taking advantage of their different rates of movement in a solvent over an adsorbent medium. Gas Chromatography (GC) is a means of separation and analysis that utilises fractional separation. It is based on the principle that if a fluid containing a number of substances is allowed to pass through an adsorbent medium , the different substances in the fluid may travel at different rates and be separated.

The approximate volume injected through an inlet by using a split injection into a Gas Chromatography (GC) contains a sample with an approximate value of analyte which varies from  1-10 μL.

In order to adjust for injection volume inaccuracy, the technique used is known as  Internal Standard.

the formula for the conversion of temperature from degree celsius to kelvin is:

the sample of water at is converted to kelvin temperature by using the above formula as:

on comparing the two samples of water at or we can say that at and at respectively. the difference between the temperatures of two samples of water is:

hence, one can say that the sample of water at is greater than the sample of water at by .

the objects have the same charge.
