Clandestine Laboratory (Equipment Calibration (Must be calibrated to…
PPE, gas monitors, must carefully dismantle to make it safe. Sample items and then maintain chain of evidence.
Hand-held gas meters:
Monitor for hazardous fumes, gases, pH3, NH3(poisonous) & O2 level, must calibrate to determine if the environment is safe. LEL- lower explosive level
Must be calibrated to standards, also applied in the field. Register all equipment & keep up to date on when calibrations are needed.
must check peaks are where they should be, do they match the standards, if not right recalibrate.
At Scene of the crime:
- ensure stored properly & in date.
(take some out w/ pipette to avoid contamination)
At the Lab:
maintain storage conditions to prevent deterioration- QA: must maintain integrity, appropriate conditions, alarm & monitor.
Must demonstrate evidence has not been tampered with
Document Control: QC
Working best practice, major chargers are heavily contested- must demonstrate what we are doing. International & professional standards & community expectation. Say what you do, do what you say, prove it, improve it.
Must follow the process, must ensure cross training to get the right samples.
Client agreements, procedures & instructions. policies & guideline. Methods/SOP's, technical records. Must make records of all changes, changes must be authorised.
Covert illegal operation that produces a controlled substance through the modification of raw materials. Uses improvised equipment.
purchasing , tenders & contracts, documentation & document control, complains, control of NC, corrective & preventive action, control of records (test & quality), internal audits.
handling & identification & traceability of samples, continuity, control of equipment, training, proficiency testing, reporting.
sample storage, instrument calibration, reporting, monitor the effectiveness & make improvements if needed.
QC- known concentration, level of purity, where is the error occurring? can we isolate it,
the range of values within the measured value that can be said to lie with in a LOC. Record the lowest value. Where did it come from: balance, pipette, injector, detectors, software
