So far, we have been asking users to switch the RF cable at the Probehead, depending on whether you run a 13C or 19F observation.\u00a0 \u00a0Many a time, a slip in this step leads to ‘zero signal’ since you might be pulsing along the wrong Channel.<\/p>\n

Now, this problem is gone once and for all with the following home-made upgrade.\u00a0 The attached picture should say it all.\u00a0 \u00a0\u00a0<\/strong><\/p>\n

\"\"<\/a>

Simple dial operation (Pull, Turn and Push) can switch between 13C and 19F.<\/p><\/div>\n

AFTER<\/strong> you select your 13C<\/strong> or 19F<\/strong> experiment and BEFORE <\/strong>you run the ‘wobb’ command, make sure that the dial is pointing towards the correct nucleus.\u00a0 If not, you just need to do the following sequence of actions with the black knob :<\/p>\n

    \n
  • \n

    PULL<\/strong><\/h3>\n<\/li>\n
  • \n

    TURN<\/strong><\/h3>\n<\/li>\n
  • \n

    PUSH <\/strong><\/h3>\n<\/li>\n<\/ul>\n

    That’s it !\u00a0 Now you are ready to scan the nucleus of your choice.<\/p>\n

    WARNING !!!\u00a0<\/strong><\/span>\u00a0 NEVER TURN\/MANIPULATE THE KNOB, WHEN\u00a0 AN ACQUISITION (ZG) IS IN PROGRESS !!<\/strong><\/h2>\n

    If you have doubts, please clear them first.<\/strong><\/h3>\n
