XRF Short Courses

(I) On-line Virtual XRF Short Course
     XRF2021   June 21 - June 25, 2021

The course is primarily intended for people with some experience with XRF or other atomic spectrometric techniques.  For new or soon to be users, we encourage you to contact the course coordinator to see if this course will be a good fit for your background.  The course is intensive and does require participants to do calculations for some of the practical exercises.  A laptop is required to view some of the course material in colour (handouts are black and white but full colour electronic copies are supplied on a memory stick), and many delegates find the calculations easier on a spreadsheet than on a calculator. 

Course Format:

- 5 days: Monday - Friday

- Mornings: Online lectures each morning

- Afternoons: Practical Exercises Assigned each afternoon with online support

    (II) Advanced XRF Method Development Course (for 2022 ...)

    Advance XRF Course is in a NEW format, concentrating on the practical Method Development aspect for new applications. The approach is following Good Laboratory Practice (GLP) guidelines and enriched with many real-world examples from the experience of the lecturers. The aim is to ingrain the steps, thus giving the participants a framework and successful tools. Once completed, the participants will be more successful in developing methods and able to deliver better methods in a shorter time.

    Advanced XRF Method Development Course is built on the fundamentals of XRF from the above course. Because of the intense and demanding nature of the program, prior attendance at the above short course is required. In exceptional circumstances, a participant may be accepted where their background and experience are considered equivalent.

    However, Advance XRF Method Development Course will be offered only every 2 or 3 years depending on interest.
