Operator: Laboratory

MAIN PURPOSE OF THE JOB:

To provide technical assistance in the operations of the Laboratory by accurately and precisely carrying out all production related analysis and test work, within the required time specifications in a safe and efficient manner.

Key Performance Areas:

• Receive and prepare samples.
• Analyse samples as per Standard Operating Procedure.
• Calibrate all instruments before analyzing samples and troubleshoot complex calibration issues.
• Communicate equipment problems and accuracy of sample results, take corrective actions and troubleshoot complex situations.
• Standardize make up reagents/ solution before starting with analyses.
• Insert QA/QC samples on batch created for XRF, ICP and Reagent titrations.
• Clean milling bowls/ pots with cleaning material to avoid cross contamination
• Rinse pipette with demin water after each sample solution.
• Calculate and determine amount of chemicals required for reagent make-up.
• Prepare the necessary dilutions/ molarity adjustment and\or chemicals as required for standardizations.
• Carry out basic repair and routine maintenance for laboratory equipment and instruments.
• Lock out, positively isolate equipment and attend to routine maintenance and basic repair on laboratory equipment and instrumentation.
• Inspect and check all apparatus/ instrument before use and report all malfunctions and faulty to line immediately.
• Ensure that all solution dispersers are dosing correctly using density calculations.
• Replace gas bottle for instruments, ensure that sufficient gas cylinders are in place and empty bottles are returned.
• Dismantle and clean burette of automatic titrator to prevent leakages of titrant that can damage to auto burette and inaccurate results.
• Dismantle torch, nebulizer of ICP machine and clean regularly.
