We often get asked about the maximum temperature limit of our packed columns, so I decided to write a post series that will provide this information for the majority of the packed columns which we sell.  I thought I would start with the least complicated packed columns, those whose packings are typically not coated with a liquid phase.  These packings include porous polymers.<\/p>\n\n\n\n

For this post, I will only be focusing on HayeSep, Porapak, and Tenax packings.  I decided not to include Chromosorb porous polymers because they are either in short supply or currently unavailable.<\/p>\n\n\n\n

I am going to make the following assumption:<\/strong>  The column\u2019s maximum temperature is limited to the packing, and not the column’s tubing; end plugs; fittings\/adaptors; and\/or ferrules used for installation. If you have a packed column that includes nonmetal tubing or end plugs other than glass wool or metal, contact Restek.<\/p>\n\n\n\n

Please note<\/strong>:  The catalog (part) numbers shown below are just for the packing and not any packed column.<\/p>\n\n\n\n

Keep watching for future posts on maximum temperatures of packed columns.  Thank you.<\/p>\n\n\n\n
