Educational objectives To equip the students with the knowledge of:   (1) optimization of instrument conditions  (2) ion elution in isocratic and gradient conditions; (3) gradient and concentration influence on ion separation and selectivity; (4) IC analysis method optimization

Prerequisite and background Students must already be familiar with the basics of Ion chromatography and have to pass the entrance test before lab work. The test is uploaded on Moodle. The introductory lecture related to an overview of the instrument work and lab rules is performed by Ion chromatography laborotory staff with remote access from the classroom to the laborotory. Students receive an introduction about lab work and the instrument. Before the remote visit to the laborotory students should view the educational materials uploaded on Moodle (http://mdl.netchem.ac.rs/course/view.php?id=25#section-4) and prepare themselves for the discussion.

The student has to: 1. Succesfully pass the Moodle entrance test 2.

Remote Access Connection Instructions What makes these lectures different and unique from other classroom lectures is that we have incorporated a section in each activity to remotely acess laboratories, lecturers from your classroom. Request a remote lecture/ lab session specifying information such as: the day, the time, and the instrument you are interested in using by visiting our web site: http://netchem.ac.rs/remote-access You will see the list of partners with the instruments provided to chose from. You will be contacted by a Remote Access staff member to set up a test run to ensure you are set up properly and have the required infrastructure. In some cases it will be possible to send samples or verify the in-house sample you would like us to prepare and load for characterization. There are two communications software packages, that will allow us to communicate instructions and answer questions during the session. - TeamViewer: You can obtain a free download at: https://www.teamviewer.com/en/index.aspx - Skype

Remote Access Connection Instructions You will need: Computer with administrator access to install plug-ins and software An internet connection Speakers Microphone Projector connected to the same computer Web browser (Firefox preferred) Camera During the test run you can refer to this guide to perform the following steps, but it’s very important that you only proceed with these steps during your scheduled times. You may interfere with other remote sessions and potentially damage equipment if you log in at other times. Open and logon to your Team-viewer account. You will be given the access code to enter at the time of your test and then again during the remote session. If you are using the Team-viewer software, Remote Access staff will give you the Meeting ID. You should soon see the Remote Desktop Share or Video Conference and at this point you can see what is on the screen as if it were your desktop or live video connection (in real time) from laboratory . Switch to full screen mode by selecting the maximize screen option in the top right corner of the screen. Upon completion of the session, move your mouse to the top right corner of the screen, and click on the X to disconnect the remote session.

Remote Access Connection Instructions Instructions for using team viewer are in detail explained in Deliverable 2.2 named Guidelines for courses publishing by WARIAL networking (http://www.netchem.ac.rs/documents/category/52-deliverables) In brief, The meeting function allows a host to present video call (Video Conference) from a laboratory or the content of his screen (Remote Desktop Share) to other participants (guest). Up to 25 users can join a meeting. For both cases Educational (one side is dominantly receptive) and Consultative (two sides are equal in giving-receiving information) types of information exchange Video Conference and Remote Desktop Share can be arranged.

SETTING UP A MEETING (for host) To host a meeting, switch to Meeting tab in TeamViewer main window. In the Start meeting area, click on Presentation or Video Call. Session will start with certain Meeting ID (a 9-digit code, randomly generated for each session). If the invited participant is in the contacts list (My Computers list), just click on their name. If not, they will need to receive a Meeting ID via phone/e-mail. A list of all the participants will appear in Participants widget. Through this list, the presenter can manage privileges of each attendee. When all participants join a meeting, video call or presentation can start. SETTING UP A MEETING (for guest) To attend a meeting, if you are invited via presenter's contact list, an invitation message will appear. Simply click on Join button to join the meeting or if you are invited via phone/e-mail, enter the provided Meeting ID, and some informative alias (e.g. your name and/or institution) into Your name field, and click Join meeting. Regardless of joining method, two windows will appear: the window with presenter's desktop content or window with all video links of all participants, that is the center of all activities, and TeamViewer Panel (that can be hidden or displayed anytime by clicking the icon on its left side).

WHATEVER YOUR ROLE IS YOU CAN SHARE FILES AND CHAT (see instructions at http://www.netchem.ac.rs/documents/category/52-deliverables)
