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.
Which instrument used to calibrate ammeter?
It is a potentiometer.

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
What determines the accuracy of an instrument'?
A variable that could influence the accuracy of an instrument is the reference standard that was used to calibrate the instrument.
What are 3 types of chromatography?
1. thin -layer chromatography 2. gas chromatography 3. liquid chromatography
Is planar chromatography same as gas chromatography?
No, they are different techniques.
Who would calibrate a multimeter?
An electrician, it is an electronic measuring instrument
What variables determine the accuracy of an instrument?
A variable that could influence the accuracy of an instrument is the reference standard that was used to calibrate the instrument.
What is a Gas Chromatography-Mass Spectrometer?
A Gas Chromatography-Mass Spectrometer (GC-MS) is an analytical instrument used to separate and identify chemical compounds in a mixture. The gas chromatography component separates the compounds based on their physical properties, while the mass spectrometer identifies the compounds based on their mass-to-charge ratio. This powerful technique is commonly used in forensics, environmental analysis, and drug testing.
What is retantion time of cyclohexancarboxaldehyde in gas chromatography?
The retention time of cyclohexanecarboxaldehyde in gas chromatography can vary based on the specific chromatographic conditions used, such as the type of column, temperature, and carrier gas flow rate. It typically falls within a range of a few to several minutes.
