Unit I – Pharmaceutical Definition, Scope & Errors Details
Pharmaceutical Analysis I – BPharma 1st Semester (AKTU & PCI Syllabus)
At FirstHope, we offer precise, exam-oriented notes aligned with the PCI-approved B Pharma syllabus. Unit I of Pharmaceutical Analysis introduces key concepts like concentration methods, standard solutions, and analytical errors. Therefore, a strong grasp of this unit is vital for semester success and exams like GPAT and NIPER.
(a) Pharmaceutical Analysis: Definition, Scope & Errors
- It defines the process of identifying and quantifying drugs.
- Moreover, it covers various techniques of analysis like titrimetry and gravimetry.
- Methods to express concentration include molarity and normality.
- It also involves primary and secondary standards for accuracy.
- Additionally, standard solutions like oxalic acid, NaOH, HCl, etc., are prepared and standardized.
(b) Errors in Analysis
- Errors arise from instruments, methods, or human factors.
- They are mainly classified into systematic and random errors.
- To reduce these, one must apply proper techniques and maintain accuracy and precision.
- Besides, using significant figures enhances result reliability.
(c) Pharmacopoeia and Impurities
- Pharmacopoeias offer official standards for drugs.
- Impurities may come from raw materials, processing, or storage.
- Therefore, limit tests are performed to ensure purity.
