Shape selectivity Tanaka test

FIGURE 5.4 Comparison of shape selectivity and planar recognition test procedures SRM 869a test (solutes PhPh, TEN, BaP eluent acetonitrile/water 85/15 (v/v), flow 2 ml/min, detection UV 254 nm) and Tanaka test (solutes o-TER, TRI eluent methanol/water 80/20 (v/v), flow 1 ml/min, detection UV 254 nm.

Another informative test mixture is that described by Tanaka [43], in which selectivity between triphenylene (TRI) and o-terphenyl (o-TER) is used to characterize the shape recognition capability of LC stationary phases. The primary difference between these two solutes is their planarity TRI is a planar PAH and o-TER possesses...
