Advantages and Disadvantages of Chromatography

 Some advantages and disadvantages of chromatography are discussed below. So let us check out its advantages and disadvantages to know more about chromatography.

Some Advantages of Chromatography are:

1. Chromatography can separate complex mixtures with great precision.
2. High resolution and sensitivity.
3. It can handle small sample sizes.
4. Fast analysis method.
5. It separate compounds based on their chemical properties. 
6. Different compound moves at different speeds. 
7. It is suitable for a wide range of compounds. 
8. Chromatography can separate isomers and enantiomers.
9. It allows easy quantification.
10. Chromatography is versatile and adaptable to different needs.

Some Disadvantages of Chromatography are:

1. Chromatography method is expensive. 
2. Costly materials and equipments are used.
3. It requires skilled personnel and maintenance.
4. Chromatography needs specific conditions and environments.
5. Initial investment can be high. 
6. Chromatography continuously needs solvents and gases.
7. High energy consumtion during chromatography analysis.
8. Analysis can sometimes be time consuming.
9. Multiple runs may be necessary.

Advantages and Disadvantages of Gas Chromatography (GC)

 Some advantages and disadvantages of Gas Chromatography are discussed below. So let us check it out its advantages and disadvantages to know more about gas chromatography.

Advantages of Gas Chromatography GC are:

1. Gas chromatography has high resolution power compared to other methods.
2. GC has high sensitivity.
3. High peak capacity.
4. Gas chromatography has high accuracy and precision.
5. It can separate complex mixtures.
6. It is used to resolve closely related compounds.
7. Small sample volume can be separated using gas chromatography.
8. Quantitative analysis is possible using GC.
9. GC can be coupled with mass spectrometry.

Disadvantages of Gas Chromatography GC are:

1. Gas chromatography is limited to volatile compounds.
2. Non-volatile compounds don't vaporize.
3. Analyte can decompose at high temperature.
4. Analyte can also react with stationary phase.
5. It is limited to low to medium molecular weight.
6. It is incompatible with aqueous samples.
7. Thermal stability is required during separation through gas chromatography.
8. It is not suitable for high-boiling compounds.
9. It is not sutable for polar analytes. 

How could thin layer chromatography be used to aid in the identification of a compound?

 Thin layer chromatography (TLC) is a technique used to separate and identify components of a mixture. It is commonly used in organic chemistry to identify unknown compounds. In TLC, a stationary phase (such as a glass or plastic plate) is coated with a thin layer of adsorbent material. When the mixture is applied to the plate, the different components of the mixture separate based on their relative affinities for the stationary phase. By comparing the positions of the components on the plate to standards, it is possible to identify the components in the mixture.

Why did the liposomes fluoresce during size-exclusion chromatography?

Liposomes fluoresce during size-exclusion chromatography because they contain fluorescent compounds. These fluorescent compounds are often incorporated into the liposomes during the manufacturing process in order to provide a way to track the size of the liposomes as they pass through the chromatography column. The fluorescent compounds can be detected by a detector, which then provides information about the size of the liposomes. 

What is the role of producer top management and QAS towards quality assurance in BRD?

 The role of producer top management and QAS towards quality assurance in BRD is to establish a clear quality assurance policy and objectives. They should also ensure that adequate resources are allocated to quality assurance activities and that these activities are carried out in a systematic and planned manner. Furthermore, they should monitor the effectiveness of quality assurance activities and take corrective action where necessary.

What questions are asked by managers of pharmaceutical companies of their quality assurance people?

 1. What quality assurance procedures does your company have in place?

2. How do you ensure that your products meet quality standards?

3. What are your procedures for investigating quality issues?

4. What quality metrics do you track?

5. How does your company handle non-conforming products?

6. What corrective and preventative actions have you taken in response to quality issues?

7. What trends are you seeing in your quality data?

8. How has your quality management system evolved over time?

9. What challenges do you face in maintaining quality standards?

10. What role do quality assurance personnel play in your company's operations?

Full Form of API in Pharma Industry

FULL FORM OF API

What is the full form of API in pharma industry?

• Answer:
• Active Pharmaceutical Ingredient

API is the central ingredient or the main ingredient used in medicines or pharmaceutical products. Substance other than API are called excipients. In simple words we can say that API is the chemical used in medicine which causes direct effect on the disease.
