There are three isomers with the following chlorine substitutions; 1,2,3,4 \/ 1,2,3,5 \/ 1,2,4,5. While the chemical industry measures these compounds for purity they are also found in the environment as the result of leaking transformers and to a lesser extent from the manufacture of paper. In the pulp and paper industry these compounds can be a byproduct of the bleaching process which uses chlorine and chlorine dioxide (2).<\/p>\n\n\n\n<p>Image of 1,2,3,4- tetrachlorobenzene.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"649\" height=\"535\" src=\"https:\/\/discover.restek.com\/wp-content\/uploads\/blog-tetrachlorobenzene-isomers-added-to-proezgc-01.png\" alt=\"\" class=\"wp-image-16978\" title=\"-\" srcset=\"https:\/\/discover.restek.com\/wp-content\/uploads\/blog-tetrachlorobenzene-isomers-added-to-proezgc-01.png 649w, https:\/\/discover.restek.com\/wp-content\/uploads\/blog-tetrachlorobenzene-isomers-added-to-proezgc-01-300x247.png 300w\" sizes=\"auto, (max-width: 649px) 100vw, 649px\" \/><\/figure>\n\n\n\n<p><a href=\"https:\/\/pubchem.ncbi.nlm.nih.gov\/compound\/tetrachlorobenzene#section=3D-Conformer\" target=\"_blank\" rel=\"noopener\">https:\/\/pubchem.ncbi.nlm.nih.gov\/compound\/tetrachlorobenzene#section=3D-Conformer<\/a><\/p>\n\n\n\n<p>We have had several requests for these compounds and have added them to the over 500 compounds currently on the Rxi-624Sil MS ProEZGC library.<\/p>\n\n\n\n<p>On the Rxi-624Sil MS, the isomers elute in the order as they are listed below:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>1,2,3,5- Tetrachlorobenzene<\/li>\n\n\n\n<li>1,2,4,5- Tetrachlorobenzene<\/li>\n\n\n\n<li>1,2,3,4- Tetrachlorobenzene<\/li>\n<\/ul>\n\n\n\n<p>\u00a0Figure 1: Shows the Tetrachlorobenzene isomers with alkanes on the Rxi-624Sil MS.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"600\" src=\"https:\/\/discover.restek.com\/wp-content\/uploads\/blog-tetrachlorobenzene-isomers-added-to-proezgc-02-1024x600.png\" alt=\"\" class=\"wp-image-16984\" title=\"-\" srcset=\"https:\/\/discover.restek.com\/wp-content\/uploads\/blog-tetrachlorobenzene-isomers-added-to-proezgc-02-1024x600.png 1024w, https:\/\/discover.restek.com\/wp-content\/uploads\/blog-tetrachlorobenzene-isomers-added-to-proezgc-02-300x176.png 300w, https:\/\/discover.restek.com\/wp-content\/uploads\/blog-tetrachlorobenzene-isomers-added-to-proezgc-02-768x450.png 768w, https:\/\/discover.restek.com\/wp-content\/uploads\/blog-tetrachlorobenzene-isomers-added-to-proezgc-02.png 1494w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n<\/div>\n\n\n<p>&nbsp;<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Government of Canada. 1993.
