NZQA registered unit standard 12363 version 4 Page 1 of 4 Title Demonstrate knowledge of chromatography systems Level 5 Credits 4 Purpose People credited with this unit standard are able to: describe chromatography, the distribution between phases in a chromatographic separation, and the instrumental components of a chromatographic system; quantify the components of a mixture from chromatographic results; and recommend a chromatographic system for a given sample. Classification Science > Chemistry Available grade Achieved Explanatory notes 1 All work must be carried out in accordance with the quality management system, documented protocol system or Standard Operating Procedures typically acceptable in a commercial or research laboratory. 2 Health and Safety practices must conform to Australian/New Zealand Standard AS/NZS 2243:2006 Set – Safety in Laboratories Parts 1, 2, 3, 7, and 10 available at http://www.standards.co.nz and http://infostore.saiglobal.com/store. 3 Legislation applicable to this unit standard includes: Health and Safety in Employment Act 1992; Hazardous Substances and New Organisms Act 1996. 4 The chromatography systems covered by this unit standard are: Gas Liquid Chromatography (GLC); High Pressure Liquid Chromatography (HPLC); and Ion Chromatography. Outcomes and evidence requirements Outcome 1 Describe chromatography. Evidence requirements 1.1 Chromatography is described in terms of separation using mobile and stationary phases. NZQA National Qualifications Services SSB Code 130301 New Zealand Qualifications Authority 2016 NZQA registered unit standard 1.2 12363 version 4 Page 2 of 4 Chromatography is described in terms of workable phase combinations. Range evidence of two examples of workable phase combinations is required. Outcome 2 Describe the distribution between phases in a chromatographic separation. Evidence requirements 2.1 The distribution is described in terms of the system characteristics affecting the separation. 2.2 The distribution is described in terms of the sample characteristics. 2.3 Examples of sample component are given, and the order of elution of the sample component is predicted in accordance with the chromatographic procedure. Range evidence of two examples of elution component is required. Outcome 3 Describe the instrumental components of a chromatographic system. Evidence requirements 3.1 The mobile phase delivery system is described in terms of its composition and requirements. 3.2 The sample delivery system is described. Range 3.3 The column characteristics are described. Range 3.4 septum, heated port, valve and loop; HPLC – valve and loop. column dimensions, stationary phase, support. The detection system is described. Range thermal conductivity detector (TCD) and flame ionisation detector (FID); ultra violet (UV) and refractive index (RI); for Ion Chromatography – conductivity. NZQA National Qualifications Services SSB Code 130301 New Zealand Qualifications Authority 2016 NZQA registered unit standard 12363 version 4 Page 3 of 4 Outcome 4 Quantify the components of a mixture from chromatographic data results. Range external calibration curve, internal standard calculation where sample and standards contain equal amounts of internal standard. Evidence requirements 4.1 Components are quantified consistent with the data results. Outcome 5 Recommend a chromatographic system for a given sample. Range sample may include – volatile and non-volatile organics, inorganic gases, aqueous-based solutions. Evidence requirements 5.1 The chromatographic system is selected and recommended in accordance with the sample characteristics.

Please note Providers must be granted consent to assess against standards (accredited) by NZQA, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment. Industry Training Organisations must be granted consent to assess against standards by NZQA before they can register credits from assessment against unit standards. Providers and Industry Training Organisations, which have been granted consent and which are assessing against unit standards must engage with the moderation system that applies to those standards. NZQA National Qualifications Services SSB Code 130301 New Zealand Qualifications Authority 2016 NZQA registered unit standard 12363 version 4 Page 4 of 4 Requirements for consent to assess and an outline of the moderation system that applies to this standard are outlined in the Consent and Moderation Requirements (CMR). The CMR also includes useful information about special requirements for organisations wishing to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
