following workplace safety procedures.
Must provide evidence that demonstrates knowledge of:
principles and concepts underpinning the analysis, including:
nature of specific sample matrices
effects of interferents with analyte behaviour, such as ionisation, complexation, precipitation, masking and association
quantification methods, such as internal standards, standard additions, Gran's Plot and recovery checks
chemical and physical treatments to minimise interferences

spectral interference
problems associated with the physical state of the analyte, such as blockages and viscosity changing flow rates to instruments
basic equipment maintenance procedures
calculation steps to give results in appropriate units, precision and uncertainty
workplace and legal traceability requirements

Judgment of competence must be based on holistic assessment of the evidence. Assessment methods must confirm consistency of performance over time, rather than a single assessment event.
This unit of competency is to be assessed in the workplace or a simulated workplace environment. A simulated workplace environment must reflect realistic operational workplace conditions that cover all aspects of workplace performance, including the environment, task skills, task management skills, contingency management skills and job role environment skills.
Foundation skills are integral to competent performance of the unit and should not be assessed separately.
Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
Knowledge evidence may be collected concurrently with performance evidence or through an independent process, such as workbooks, written assessments or interviews (provided a record is kept in each case).
This unit of competency may be assessed with:
MSL925001 Analyse data and report results
Holistic assessment methods include:
review of test data/results obtained by the candidate over time to ensure accuracy and consistency of results
inspection of test records and workplace documentation completed by the candidate
observation of candidate conducting a range of complex tests to measure chemical properties of materials
feedback from clients, peers and supervisors about the candidate’s ability to provide valid and reliable results within expected timeframes
oral or written questioning of relevant chemical principles, concepts, sample preparation, isolation of analytes, analytical techniques and workplace procedures.
Access is required to instruments, equipment, materials, workplace documentation, procedures and specifications associated with this unit, including, but not limited to:
a standard laboratory with specialised analytical instruments, laboratory reagents and equipment, standard operating procedures (SOPs) and test methods.
Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.
The assessor must demonstrate both technical competence and currency.
Technical competence can be demonstrated through:
relevant VET or other qualification/Statement of Attainment AND/OR
relevant workplace experience.
Currency can be demonstrated through:
performing the competency being assessed as part of current employment OR
having consulted with a laboratory about performing the competency being assessed within the last twelve months.
