Expanding the term "Design Space" in high performance liquid chromatography (I).

Journal of pharmaceutical and biomedical analysis

Monks KE, Rieger HJ, Molnár I.
PMID: 21893394
J Pharm Biomed Anal. 2011 Dec 15;56(5):874-9. doi: 10.1016/j.jpba.2011.04.015. Epub 2011 Apr 22.

The current article presents a novel approach to applying Quality by Design (QbD) principles to the development of high pressure reversed phase liquid chromatography (HPLC) methods. Four common critical parameters in HPLC--gradient time, temperature, pH of the aqueous eluent,...

Electrochemical study of some 2-mercapto-5-R-ammino-1,3,4-thiadiazole derivatives using carbon paste electrodes.

Journal of pharmaceutical and biomedical analysis

Kauffmann JM, Mirel S, Roman L, Sandulescu R.
PMID: 9919953
J Pharm Biomed Anal. 1998 Dec;18(4):535-44. doi: 10.1016/s0731-7085(98)00282-9.

The electrochemical study of some 2-mercapto-5-R-ammino-1,3,4-thiadiazole derivatives was made by cyclic and linear sweep voltammetry using a carbon paste electrode (CPE, graphite/solid paraffin ratio 2:1) as working electrode and an Ag/AgCl reference electrode. The current-potential curves were recorded in...
