						<title>Solvent Choice</title>
<link>http://www.cem.com/e107_plugins/forum/forum_viewtopic.php?127</link>
<description><![CDATA[I'm am planning to perform a MW synthesis using diethylene glycol monomethyl ether but was curious to know what other high boiling point solvents I could use that would act the same under MW conditions. Does anyone have experience using glycol ethers as solvents? The reaction would be run at 180 degrees for 10 mins.]]></description>

<description><![CDATA[Hi<br />As we are several users of the CEM-liberty, it would be a great if everyone could have their personal folder containg their own methods. Is this possible and how about subfolders in the sequence and cycles editor, is that possible?<br /><br /><br />In  advance thanks<br />Erik]]></description>

						<title>Cys-His racemization in peptide synthesis</title>
<link>http://www.cem.com/e107_plugins/forum/forum_viewtopic.php?108</link>
<description><![CDATA[well, During conventional stepwise Fmoc-based solid phase peptide synthesis, base-catalyzed acylation methods lead to considerable racemization of Cys(Trt)- assembled peptide fragments during the activation/coupling process (same with His), lower temperatures helps to avoid it. However,  people suggest to use other kind of couplig conditions like using DIC non base-catalyzed and room temperature, could we use this coupling conditions in microwave synthesis at 55ªC?]]></description>

						<title>Chemmatrix Resin Swelling considerations</title>
<link>http://www.cem.com/e107_plugins/forum/forum_viewtopic.php?107</link>
<description><![CDATA[Hi<br />I have heard a lot of good things about the Chemmatrix resins, so now I've ordered some.<br />However I'm concerned with the swelling of the Chemmatrix resin, as you want the resin to be completely soluted during the various steps. So as the swelling of the Chemmatrix resin is around twice as big as for PS resin, I'm wondering whether it is necessary to take any precautions when using this resin?<br /><br />In advance thanks<br />Erik]]></description>

						<title>Resin mesh size</title>
<link>http://www.cem.com/e107_plugins/forum/forum_viewtopic.php?103</link>
<description><![CDATA[Hi<br />I just downloaded the latest version of the usermanual for the 12C Liberty, and I just had a glance at it. I seem to recall that somewhere it says that the resin mesh size to be used with the LIberty should be 100-200. Can anybody confirm this.<br /><br />In advance thanks<br />Erik]]></description>

<description><![CDATA[Well I thought it could be a god idea to have a thread where people can exchange experience concerning error issues and troubleshooting.  So I'll go first :] Lately our yields have been quite low and we have had some error messages upon deprotect addition. <br /><br />The service technician will not be able to be here untill another 2 weeks, so any help is appriciated.

						<title>calculations</title>
<link>http://www.cem.com/e107_plugins/forum/forum_viewtopic.php?93</link>
<description><![CDATA[Hello:<br /><br />i notice during my calculation using pepDriver software calculator that no mater what the scale of my synthesis, still the concentration of the activator at 0.5 M and aa at 0.2M. i wonder if this normal or i am missing something during calculation. how the machine adjust the amount of activator and aa for different scales? and if the machine does this, should the concentration of high scale become more diluted than the low one??]]></description>

						<title>Favorite Activators</title>

<description><![CDATA[In the labs here at CEM, we're tried many different activators over the years, and we've found every activator we've tried has performed well in the microwave.  Which activators have you tried, and what's become your favorite activator?]]></description>
