A combination of non-polar and shape selective columns in a comprehensive two-dimensional GC (GCxGC) system consisting of DB-5MS and LC-50 as the 1st and 2nd dimension columns was used to separate 22 tetrachloronaphthalene isomers. These columns enabled separation of all possible isomers of tetraCN found in the technical chloronaphthalene Halowax formulations into 18 peaks covering 15 single separated isomers and 7 co-eluting in triplicate (1,2,4,6-/1,2,4,7-/1,2,5,7-tetraCN; nos. 33/34/37) and in pairs (1,2,3,7-/1,2,4,5-tetraCN; nos. 30/32 as well as 1,3,5,8-/1,3,6,8-tetraCN; nos. 43/45). Twelve isomers of tetraCN resolved as single compounds by the GC x GC system used were found in Halowax 1001, 1013, 1014 and 1099 as well as in Equi-Halowax mixture. Three other tetraCNs that could be also resolved as single compounds were not detected in these materials, while the remaining 7 tetraCNs, which co-eluted, waits a further separation. The majority of constituents of the tetraCN homologue group of the Halowax formulations are isomers such as 1,4,5,8- (no. 46), 1,2,5,8- (no. 38), 1,2,4,8-tetraCN (no. 35), co-eluting 1,3,5,8-tetraCN (no. 43 in a pair nos. 43/45) and also co-eluting 1,2,4,6-/1,2,4,7-/1,2,5,7-tetraCN (nos. 33/34/37). The less abundant by amongst of tetraCNs in these mixtures are 1,4,6,7- (no. 47) and 1,3,5,7-tetraCN (no. 42). The remaining seven isomers, i.e., 1,2,3,4- (no. 27), 1,2,3,5- (no. 28), 1,2,3,6- (no. 29), 1,2,5,6- (no. 36), 1,2,6,7- (no. 39), 1,2,6,8- (no. 40) and 1,2,7,8-tetraCN (no. 41) are usually minor by quantity, while 1,2,3,7-/1,2,4,5-tetraCN (nos. 30/32) are also minor, or one of them is absent. Three tetraCNs not found in the Halowax formulations are isomers such as 1,2,3,8-tetraCN (no. 31), 1,3,6,7-tetraCN (no. 44) and 2,3,6,7-tetraCN (no. 48).
在由DB - 5MS和LC - 50分别作为第一维和第二维色谱柱组成的全二维气相色谱（GCxGC）系统中，使用非极性和形状选择性色谱柱的组合来分离22种四氯萘异构体。这些色谱柱能够将工业氯萘Halowax配方中发现的所有可能的四氯萘异构体分离为18个峰，涵盖15个单一分离的异构体以及7个以三重峰形式共洗脱的异构体（1,2,4,6 - /1,2,4,7 - /1,2,5,7 - 四氯萘；编号33/34/37）和以双峰形式共洗脱的异构体（1,2,3,7 - /1,2,4,5 - 四氯萘；编号30/32以及1,3,5,8 - /1,3,6,8 - 四氯萘；编号43/45）。通过所使用的GCxGC系统分离为单一化合物的12种四氯萘异构体在Halowax 1001、1013、1014和1099以及Equi - Halowax混合物中被发现。另外三种也可分离为单一化合物的四氯萘异构体在这些材料中未被检测到，而其余7种共洗脱的四氯萘异构体有待进一步分离。Halowax配方中四氯萘同系物组的大多数成分是异构体，如1,4,5,8 - （编号46）、1,2,5,8 - （编号38）、1,2,4,8 - 四氯萘（编号35）、共洗脱的1,3,5,8 - 四氯萘（编号43，在编号43/45的一对中）以及共洗脱的1,2,4,6 - /1,2,4,7 - /1,2,5,7 - 四氯萘（编号33/34/37）。这些混合物中含量较少的四氯萘异构体是1,4,6,7 - （编号47）和1,3,5,7 - 四氯萘（编号42）。其余七种异构体，即1,2,3,4 - （编号27）、1,2,3,5 - （编号28）、1,2,3,6 - （编号29）、1,2,5,6 - （编号36）、1,2,6,7 - （编号39）、1,2,6,8 - （编号40）和1,2,7,8 - 四氯萘（编号41）通常数量较少，而1,2,3,。
