IR Chromatography

What is the principle of IR chromatography?

• Separation of sample components based on size

• Detection of sample components using UV radiation

• Analysis of sample components using visible light

• Interaction between sample components and infrared radiation

Name the types of IR chromatography.

• GC, LC, TLC

• GPC, IEC, SEC

• HPLC, TLC, SEC

• HPLC, GPC, IEC

What are the applications of IR chromatography?

• Petroleum analysis, music production, and sports equipment testing

• Agricultural research, computer programming, and art restoration

• Astronomy research, construction materials testing, and fashion design

• Pharmaceutical analysis, environmental testing, forensic analysis, and food and beverage testing

List some advantages of IR chromatography.

• Some advantages of IR chromatography include its ability to analyze a wide range of compounds, its sensitivity, and its ability to provide qualitative and quantitative data.

• IR chromatography is not sensitive

• IR chromatography does not provide qualitative and quantitative data

• IR chromatography cannot analyze a wide range of compounds

What are the limitations of IR chromatography?

• Some limitations of IR chromatography include limited sensitivity, difficulty in separating complex mixtures, and the need for specialized equipment.

• No need for specialized equipment

• Unlimited sensitivity

• Easy separation of complex mixtures

How does IR chromatography separate compounds?

• By their molecular weight

• By their color

• By their interaction with infrared light

• By their boiling point

What are the different modes of IR chromatography?

• FTIR, Raman, UV-Vis

• UV, MS, NMR

• HPLC, TLC, SEC

• GC, LC, SFC

Explain the role of mobile phase in IR chromatography.

• The mobile phase has no role in IR chromatography

• The mobile phase helps in detecting the components of the sample

• The mobile phase helps in carrying the sample through the stationary phase and separating its components.

• The mobile phase is responsible for holding the stationary phase in place

Discuss the importance of stationary phase in IR chromatography.

• It causes interference in the separation process

• It allows for the separation of different compounds based on their interaction with the stationary phase.

• It has no importance in IR chromatography

• It only works for separating compounds with similar properties

How is IR chromatography different from other chromatography techniques?

• Mobile phase

• Column material

• Detection method

• Stationary phase
