Course Description

This unit of competency covers the ability to analyse samples using routine chromatographic techniques. The unit also includes establishing client needs for routine and non-routine samples, optimising enterprise procedures and instruments for specific samples, obtaining valid and reliable data and reporting test results. Personnel are required to recognise atypical test data/results and troubleshoot common analytical procedure and equipment problems.

*This is the week when the talk is to be given, ie. the topic of the presentation is in the week before the talk. For example, TLC of vegetable pigments is done in week 3 lab class, the talk on this topic will be held in week 4. Results are to be presented along with a short discussion of trends in the data and what the results tell you about the mixture being separated. Talks should be no more than 10 minutes long. All group members must present part of the talk.

** see logbook information for what is required.

IMPORTANT POINTS TO NOTE
* If you miss a prac report class you will only be eligible to write up/present a different prac if you provide a medical certificate.  For this to occur you need to discuss your situation with the teacher as soon as possible. Other reasons for missing a write up prac do not mean that you can write up a different report.If you miss an oral report presentation day you will be able to present it at the next class you attend as long as you provide a medical certificate.

In other words
* If you miss the experiment that you are to present as an oral presentation, you may present a different experiment as long as you provide a medical certificate
* Practical report 2 is due 2 weeks after the day that the practical is performed.
* Students must attend at least 80 % of practical classes to pass the course.
* Students must pass all of the assessment tasks to pass the course.
* ***Reports (powerpoint for oral presentation or word document for written report) need to be submitted online via blackboard or by email to the teacher if blackboard is not available. The online plagiarism statement given in blackboard must be included with the emailed assignment to show that the student agrees to these conditions***

Logbook
Your logbook must be signed off after completion each week by both the student AND the teacher.
The teacher will also signoff your logbook on the class sheet as a central record.

The central record is the evidence record that is required to show that your logbook has been signed off by you, the student, and the teacher.

IT IS THE STUDENT’S RESPONSIBILITY TO GET THEIR WORK SIGNED OFF EVERY WEEK.
(If you miss the class you do not need to get the sheet signed off - the teacher will record this as an absence). YOU WILL BE CONSIDERED NYC* FOR THAT WEEK UNTIL THE CENTRAL RECORD IS SIGNED OFF or YOU ARE MARKED ABSENT.

*NYC = not yet competent

When is a prac performance considered "competent’ (ie when can a logbook be signed off)?
Logbooks will only be signed off when the student has followed and completed a method adequately, and is therefore considered competent for that experiment.

This is evidenced by:

THE LOGBOOK WILL ONLY BE SIGNED OFF BY THE TEACHER AFTER THE FOLLOWING IS DONE:

1. Show date of analysis/results at top of page at start of experimental record in logbook,
2. Attach loose pages to logbook securely (use tape or staples),
3. Include raw and analysed results in logbook as appropriate to particular method (see lab manual)
4. Results considered in context of expected results by answering Questions 1-4 in logbook*
5. Clean up lab work area and equipment adequately
6. Student signed off logbook entry once record of results are completed and clean up done

*Questions 1-4
If the experiment is performed and completed, there are two possibilities for obtaining competent performance of the technique:
 
A. Results are within the expected range OR
B. Results are not within expected range AND a reasonable troubleshooting and reflection process has occurred.

To provide evidence for either A or B (above) answer the following questions in the logbook after each prac:
1. Were your results in the expected range? Yes/No
2. What were the key findings/results?
3. If no, why not - what is the most likely cause of the discrepancy?
4. What would you do differently if you had the opportunity to do the experiment again?


When is a prac performance considered "not yet competent’?
(ie when will a logbook not be signed off?)

A student is considered to be ’not yet competent’ for an experiment if:

* The Student doesn’t attend class long enough to complete the experiment
* The Student doesn’t finish the procedure in a reasonable time
(nominally by the time class finishes - excluding when there are logistic issues that mean few/no one in the class finishes).
* The student doesn’t contribute to the group effort adequately
* Results are a debacle - several errors/extensive lack of following SOP (method).
* The experiment is not conducted in a safe manner
* The lab area and equipment are not adequately cleaned up

In the case of a not yet competent result, it is noted that there is no opportunity to repeat that particular experiment due to scheduling of classes. In this case, to achieve competency other experiments during the course should be done to a ’competent’ level and the student should show a good amount of improvement as semester goes along.

As evidenced by...

* Observations in class by the teacher (record reason for NYC grade)
* The attitude and work ethic of the student while doing experiments is considered appropriate by the teacher
