Overview of assessment 

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Assessors should ensure that candidates can:

  • interpret client requests, test methods and procedures accurately
  • safely set up and shut down equipment using enterprise procedures
  • check calibration/qualification status of equipment
  • prepare standards and samples appropriately
  • install and maintain a variety of chromatographic columns

Context of and specific resources for assessment 

This unit of competency is to be assessed in the workplace or simulated workplace environment.

This unit of competency may be assessed with:

  • MSL925001A Analyse data and report results .

Resources may include:

  • standard laboratory equipped with routine chromatographic equipment, laboratory reagents and equipment
  • SOPs and test methods.

Method of assessment 

The following assessment methods are suggested:

  • review of test data/results obtained by the candidate over time to ensure accuracy, consistency and timeliness of results
  • inspection of test records and workplace documentation completed by the candidate
  • feedback from peers and supervisors
  • observation of candidate applying a range of routine chromatographic techniques
  • oral or written questioning of chemical principles and concepts, chromatographic techniques and enterprise procedures.

In all cases, practical assessment should be supported by questions to assess underpinning knowledge and those aspects of competency which are difficult to assess directly.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

Access must be provided to appropriate learning and/or assessment support when required.

The language, literacy and numeracy demands of assessment should not be greater than those required to undertake the unit of competency in a work like environment.

This competency in practice 

Industry representatives have provided the case studies below to illustrate the practical application of this unit of competency and to show its relevance in a workplace setting.

Manufacturing 

Technicians who conduct chemical synthesis frequently use chromatographic methods such as thin-layer chromatography (TLC), gas chromatography (GC), high performance liquid chromatography (HPLC) and other instrumental techniques to check the identity and purity of the material they have produced. For example, a technician reacted an amine with acetic anhydride to form the acylated amine to prepare a pilot batch of material for a new application. After completing the reaction, the technician collected the product in a Buchner funnel using vacuum assisted filtration, and used chromatographic techniques to purify the material. The product was then analysed by HPLC using a number of stationary phases and solvent systems. In each case, a reference standard was run. These tests confirmed the identity and purity of the material.

Biotechnology 

Technicians in research facilities often prepare a protein by extracting it from tissue. This extraction process introduces impurities that must be removed before the purified protein is ready for use or the characterisation of its purity and molecular weight. Impurities such as salt, detergents and other proteins are sequentially removed by passing the protein extract through gel filtration columns of differing grades of chromatographic gel. For antibodies, the final column used is an affinity chromatography column. Demonstration of the purity of the protein is by the presence of one single band on an SDS-PAGE gel. The molecular weight of the protein can also be determined from the SDS gel.

Environment 

An environmental protection authority was required to sample an oil slick off Australia's coast and to take oil samples from all ships which docked in Australian ports in the 48 hours after the discovery of the oil slick. The samples were analysed by column chromatography and compared with the oil slick 'finger print' of the oil samples from all ships which may have been in the area of the oil slick. Given that the analysis involved unknown oil samples and the results would be used in court proceedings, the analysts were careful to optimise the chromatographic system for the unknown samples, ensure that appropriate quality and control procedures were employed and that the sample and analyses were performed quickly before potentially polluting ships left Australian waters. The analysts were careful to ensure that all record keeping procedures would be able to stand up to court scrutiny.
