Assisting with the processing of liquid compounds/samples using automated laboratory equipment

PAA\VQSET

vocational

This element covers the competencies required to assist in the processing of liquid samples using automated laboratory equipment such as auto-titrators, liquid handling robots, and continuous flow analyzers. Learners must demonstrate an understanding of standard operating procedures, equipment calibration, sample loading, and monitoring processes to ensure accurate and safe operation. Practical application focuses on supporting routine analysis in industries like pharmaceuticals, environmental testing, and chemical manufacturing.

Assessment Criteria

Key criteria assessors look for in your portfolio

Award credit for demonstrating the ability to follow written standard operating procedures (SOPs) when setting up and operating automated equipment.
Look for evidence that the learner correctly loads samples into the equipment without cross-contamination and verifies sample identity against work orders.
Assess whether the learner performs basic pre-use checks, such as verifying reagent levels, waste container capacity, and system calibration status.
Credit should be given when the learner monitors the equipment during operation, identifies common error messages, and takes appropriate corrective actions such as pausing runs or reporting faults.
Expect the learner to record process data accurately, including run times, instrument readings, and any deviations from expected results, in accordance with lab protocols.
Evidence must show that the learner cleans and maintains automated equipment after use, disposing of waste solutions according to safety and environmental guidelines.

Assessment Guidance

Guidance for achieving higher grades

💡In assessment scenarios, always verbalize or document your safety checks before operating any equipment, even if it's a simulated task.
💡For written assignments, emphasize the importance of following Good Laboratory Practice (GLP) principles, including traceability of samples and audit trails.
💡When describing processes, use correct technical terminology such as 'aliquot', 'aspirate', 'dispense', and 'barcode verification' to demonstrate knowledge.
💡Prepare to explain troubleshooting steps for common issues like blocked lines, air gaps, or software freezes, as this shows deeper competence.
💡Always relate practical actions back to quality control: explain how your role in assisting impacts the reliability and reproducibility of results.

Common Mistakes

Common errors to avoid in your coursework

Failing to check that the correct method or program is selected on the automated equipment before starting a run, leading to incorrect analysis.
Neglecting to prime fluid lines or purge bubbles, which can cause inaccurate sample uptake and erratic results.
Forgetting to label sample vials clearly or placing them in the wrong autosampler positions, resulting in data mismatches.
Assuming that automated equipment requires no monitoring and walking away during operation, missing alarms or malfunctions.
Inadequately rinsing sample probes between runs, causing carryover and contamination of subsequent samples.
Ignoring calibration expiry dates or using expired standards and reagents, compromising result validity.
