Pharmaceutical Analysis Experiment: Determination of Paracetamol in Tablets
Experiment Overview:
This experiment demonstrates the analysis of paracetamol in pharmaceutical tablets using high-performance liquid chromatography (HPLC). HPLC is a powerful technique used to separate, identify, and quantify components in complex mixtures. In this experiment, paracetamol is extracted from tablets and analyzed by HPLC to determine its concentration.
Materials:
Paracetamol tablets Methanol
Water HPLC system
C18 column UV detector
Step-by-Step Procedure:
1. Sample Preparation:
Weigh and grind several paracetamol tablets to obtain a fine powder. Dissolve the powder in methanol and sonicate for 15 minutes to extract the paracetamol.
* Filter the extract to remove any impurities.
2. HPLC Analysis:
Set up the HPLC system with a C18 column and a mobile phase of methanol and water. Inject a known volume of the filtered extract into the HPLC system.
* The paracetamol peak will be detected at a specific retention time by the UV detector.
3. Data Analysis:
Integrate the area under the paracetamol peak to determine its concentration. Compare the concentration of paracetamol in the tablets to the labeled concentration or a known standard.
Key Procedures:
Extraction: Efficient extraction of paracetamol from the tablets is crucial for accurate analysis. HPLC Separation: The C18 column and mobile phase are optimized to separate paracetamol from other components in the sample.
UV Detection: The UV detector provides a sensitive and specific method for detecting paracetamol. Data Interpretation: Correct integration of the peak area is essential for accurate quantification.
Significance:
This experiment showcases the application of HPLC in pharmaceutical analysis. It demonstrates the determination of paracetamol in tablets, which is important for quality control and ensuring the correct dosage in pharmaceutical formulations. The principles and techniques learned in this experiment have wide applications in the pharmaceutical industry and related fields.
