How can one identify compounds in gas chromatography?
Compounds in gas chromatography can be identified by comparing their retention times to known standards or using mass spectrometry to analyze their molecular structure.
What factors can affect the adjusted retention time in gas chromatography?
Factors that can affect the adjusted retention time in gas chromatography include the type of stationary phase, the temperature of the column, the flow rate of the carrier gas, and the chemical properties of the analyte being separated.
Why hydrogen is used carrier gas?
Hydrogen is used as a carrier gas in gas chromatography because it has good thermal conductivity, low density, and high diffusivity. This allows for high separation efficiency and faster analysis times. Additionally, hydrogen is inert and compatible with most detectors used in gas chromatography.
Identify and explain the main drawback of gas chromatography in the identification of drugs?
One main drawback of gas chromatography in drug identification is that it requires a relatively high level of expertise to operate and interpret the results accurately. Additionally, not all drugs are amenable to gas chromatography analysis due to their chemical properties and volatility. This can limit the range of drugs that can be effectively identified using this technique.
How can one interpret gas chromatography results effectively?
To interpret gas chromatography results effectively, one must analyze the peaks on the chromatogram to determine the identity and quantity of compounds present in the sample. This involves comparing retention times, peak shapes, and peak areas to known standards or databases. Additionally, understanding the principles of gas chromatography and the specific conditions used in the analysis can help in accurate interpretation of the results.
In Gas Chromatography isothermal is when the temperature is constant but what is it called when the temperature is programmed to increase?
When the temperature is programmed to increase in Gas Chromatography, it is called temperature programming or temperature ramping. This technique involves gradually increasing the temperature during the analysis to separate compounds based on their boiling points and improve resolution.
What is mean by non isothermal columns?
isothermal means 'constant temperature' so to be non-isothermal means to have non-constant temperature.

How do you calculate RSD in gas chromatography?
hoe RSD calcuate in gas chromatography
What are the different types of chromatography?
there are different types like gas chrom. and thinlayer chrom Answer: There are two types of chromatography:liquid chromatography gas chromatography
Define isothermal expansion?
Isothermal expansion is what keeps gas at a constant temperature. It works by absorbing heat in order to conserve energy.
What are 3 types of chromatography?
1. thin -layer chromatography 2. gas chromatography 3. liquid chromatography
What is energy is transferred to a gas as heat and work If there is no change in its internal energy the process is known as?
The process is known as an isothermal process. In an isothermal process, the energy transferred to the gas as heat and work results in no change in the gas's internal energy because the temperature remains constant throughout the process.
Is planar chromatography same as gas chromatography?
No, they are different techniques.
