Share your requirementsWho usually fills this role
Mostly B.Sc. or M.Sc. chemistry, B.Pharm or M.Pharm. Test at hiring with a calculation, a sample preparation and a question on out-of-specification results. Look for neatness in notebooks, patience, and honesty when results look wrong. Ask for a short practical trial and check references where possible.
Skills ladder
Stage 1
New joiner
- Prepares solutions and standards by method
- Runs routine tests under supervision
- Records raw data in the notebook
Stage 2
Independent
- Runs HPLC, dissolution and other tests independently
- Calculates and reports results accurately
- Handles instruments and calibration checks
Stage 3
Senior or lead
- Handles method issues and out-of-specification investigations
- Trains analysts and validates methods
- Supports audits and data integrity checks
Training path
First weeks
- 1
Lab safety and documentation
The QC head explains safety, notebook rules and data integrity. The joiner writes sample entries and gets feedback.
- 2
Instrument basics
A senior analyst teaches the balance, pH meter and the main instruments. The joiner prepares and tests known samples.
- 3
Method use
The senior shows the testing method step by step. The joiner repeats until results match the senior's.
First year
- 1
Supervised testing
The analyst tests real samples with a senior reviewing raw data. Differences are discussed.
- 2
Out-of-specification handling
The head teaches the steps for an unexpected result and the rule against retesting to pass. The analyst works a mock case.
- 3
Instrument care
The analyst learns calibration and logbooks. The head audits entries.
Towards senior
- 1
Investigation
The analyst joins an investigation with the head and writes the report. The report is reviewed.
- 2
Method knowledge
The senior explains method development basics. The analyst helps with a small study.
- 3
Training
The analyst trains a junior on a method. The head checks the junior's results.
Performance review
Weekly review of notebooks by the QC head, a monthly review of turnaround, repeats and investigations, and a written half-yearly review.
What to measure
| Measure | How it is seen |
|---|---|
| Accuracy and precision | Repeat tests and comparison with senior results |
| Notebook and data integrity | Audit of raw data and audit trails |
| Turnaround | Sample register |
| Instrument discipline | Calibration and log entries |
| Out-of-specification handling | Investigation records |
| Lab safety | Observation |
Evidence to bring
- Lab notebooks
- Instrument logbooks
- Sample register
- Investigation reports
- Training records
Questions to ask in the review
- Which test gives you the most trouble?
- Did any result look unusual? What did you do?
- Which instruments are unreliable?
- How much time do you spend waiting for samples?
- What data entry mistakes happen?
- What would help you learn faster?
- How do you feel about speed pressure?
- What do you want to specialise in?
Pitfalls
- Rewarding speed so analysts retest until results pass
- No training on data integrity
- Poor instrument upkeep
- Giving juniors difficult methods without support
Questions about this role
Teaching that records must be original, accurate and made at the time of work. Use real examples and audit trails. Confirm regulatory points with your adviser.
Track delays by cause. Agree sample plans with production, and treat the result as independent of speed.
Observe the technique, repeat together and check solution preparation. Retrain and recheck.
