| dc.description.abstract | Sildenafil tablet was analyzed by x-ray photoelectron spectroscopy. Sample was fixed to a stainless-steel sample holder with a copper double-sided adhesive tape. Survey spectrum, C 1s, O 1s, N 1s, S 2p, Si 2p, Mg 1s, and Na 1s core levels spectra were acquired. Results showed the presence of carbon, oxygen, nitrogen, and sulfur, elements that constitute sildenafil; however, carbon and oxygen are also found in other ingredients (excipients). Additionally, the presence of silicon, sodium, and magnesium is associated with excipients. | eng |
| dc.description.abstract-translated | Tableta sildenafilu byla analyzována pomocí rentgenové fotoelektronové spektroskopie (XPS). Vzorek Vzorek byl uchycen na ocelový držák a mědenou oboustrannou lepící 3M pásku. V přehledovém spektru byly měřeny struktury jader C 1s, O 1s, N 1s, S 2p, Si 2p, Mg 1s, a Na 1s. Výsledky prokázaly přítomnost C, O, N, S, tj. Prvků, které tvoří tuto tabletu, nicméně C a O jsou take v přísadach tablet (excipientech). Navíc byly prokázána přítomnost S, Na, a Mg, které také tvoří excipienty. | cze |
