The present invention provides a CVD material compound based on an organic ruthenium compound, the organic ruthenium compound consisting of one of cis and trans isomers of tris (2,4-octa-dionato) ruthenium (III). The organic ruthenium compound which consists of cis or trans isomer can be isolated by the steps of preparing tris (2,4-octa-dionato) ruthenium (III) in any method, making the tris (2,4-octa-dionato) ruthenium (III) adsorbed on an adsorbent including alumina, bringing the adsorbent into contact with a first solvent to elute the trans isomer and then bringing the adsorbent into contact with a second solvent having a polarity higher than that of the first solvent to elute the cis isomer.

摘要:
Disclosed herein is cis-oxalato (trans-1-1,2-cyclohexanediamine) Pt(II) optically high purity. Because of its complete optical purity, the compound is effective as raw material of such a medicine as a carcinostatic agent. The complete optical purity of the above compound may be proved by comparing the respective melting points of the cis-oxalato (trans-1-1,2-cyclohexanediamine).

Disclosed herein is a process of optically resoluting optically active platinum complex compounds which comprises optically resoluting a d-isomer and an 1-isomer of a cis-Pt(II) complex of a 1,2-cyclohexanediamine isomer characterized in that the mixture of the d-isomer and the 1-isomer is optically resoluted by means of high performance liquid chromatography employing a column packed with a chiral filler.The chiral filler include, for example, a cellulose ester derivative, a cellulose carbamate derivative, an amylose carbamate derivative, a polymethacryl acid ester and .beta.- and .gamma.-cyclodextrin.According to the present invention, the optical resolution of a platinum complex compound essentially consisting of the mixture of two optical isomers which cannot be resoluted in accordance with a normal resolution method due to the small structural difference can be easily performed utilizing the characteristics of a chiral filler.

A test device is disclosed having a display and a graphical user interface (GUI) that provides guidance to a user by displaying first and second icons for representing first and second actions to be taken by the test device upon selecting the first and the second icons, respectively, by the user. To provide the guidance to the user, the second icon has graphical features indicative of the current status of the first action. For cases where the first action is a test that failed, the second action is highlighted thereby guiding the user to take the second action in response to the failed test. At least one of the graphical features of the second icon is indicative of whether the second icon is currently selectable by the user.
