      (Identification of the stamping time of atomic seal ink on paper by thin-layer chromatography) (Chinese)
      L. ZHANG (Zhang Lingyan)*, Z. PAN (Pan Ziqin), Q. QI (Qi Qun), J. RONG (Rong Jingyue), H. CHEN (Chen Hao) (*Coll. of Criminal Investigation, Southwest Univ. of Political Sci. & Law, Chongqing 401120, China)

      Chinese J. of Anal. Instruments (Fenxi Yiqi) (1), 58-62 (2012). The knowledge of the time when a document was created is one of the primary coverages in expert testimony. Especially the identification of the stamping time of atomic seal ink on paper is quite different from that of handwriting and common seals on paper, due to the special feature of its particular ingredient. The coloring agents such as bronze red C and phthalocyanine blue are not the same on paper and on developed silica plates because they may be oxidized and permeate gradually into the deeper layer of the paper. Also permeation of adjuvant materials to the color zone may cause cross-linked reactions. Thus the character of the ink in the extracts from the paper may be changed as time passes. The samples of atomic seal ink on paper with different stamping times were extracted with the optimized solvent system N,N-dimethylformamide – n-butanol – dichloromethane 2:1:1. TLC of the extracts on silica gel with n-amyl alcohol – cyclohexane – ethyl acetate 2:1:1. Determination of the coloring agent in the extracts by densitometry at 470 nm. Calculation of the extraction rate R = Ct / C, where Ct is the scanning peak area of the extracts obtained at different extraction duration and C is that obtained at the time when extraction reaches its equilibrium stage. Determination of the stamping time of a sample by using the calibration curves of the extraction rate against the stamping time. Demonstration of the method by determination of ten varieties of atomic seal inks containing bronze red C and and stamping times ranging from 3 to 36 months.

      Thin-layer chromatography of laser dyes and dye analogs with cyclodextrins in the mobile phase
      I.R. POLITZER, K.T. CRAGO, K. AMOS, K. MITCHELL, T. HOLLIN, (Dept. Chem., Xavier Univ., New Orleans, LA 70125, USA)

      Talanta 39, 953-958 (1992). Use of the addition of ß-cyclodextrin and its hydroxyethyl and hydroxypropyl ethers to aqueous urea-containing mobile phases to enhance the migration of various laser dyes in TLC on silica, polyamide and RP-18 silica. Examination of selected laser dyes from the coumarin, rhodamine and bimane families, as well as a number of dye analogs. Hydroxypropyl ß-cyclodextrins appeared to be the most effective for increasing dye migration.
