The UV-Visible absorbance profile of cyan, magenta, yellow and black coloured inkjet printer inks for the differentiation and comparison was obtained by scanning the ink extracts under the wavelength range of 200-800 nm. The various parameters of absorption studies of extracts of different components of printer ink formulations in the visible and UV region enables to differentiate and distinguish different colour print document samples of distinct composition by their characteristic absorbance spectra and profile pattern.Keywords

A simple and relatively less expensive UV spectrophotometric method was developed for simultaneous determination of saccharin and aspartame in soft drinks by multicomponent analysis method. Wavelengths of 235 nm and 257 nm were selected for determination of saccharin and aspartame respectively. The limit of detection for saccharin and aspartame was found to be 0.0015 g L-1 and 0.04 g L-1 respectively. The method obeys beers law within the concentration range of 0.002 g L-1 to 0.04 g L-1 and 0.06 g L-1 to 0.28 g L-1 for saccharin and aspartame respectively. This method was found to have the coefficient correlation (r2) value of 0.9997 and 0.999 for saccharin and aspartame respectively. The method was validated for accuracy, precision and repeatability. The proposed method was found to be simple, accurate, reproducible, sensitive, free form interferences, inexpensive and having good applicability to the routine analysis of samples of foods and beverages.Keywords

A study was carried out to assess the possible interference of artificial sweeteners (Saccharin, sucralose, aspartame and cyclamate) while screening for drugs and pesticides in stomach content, urine and tissues by TLC for forensic toxicological purposes. Even though these sweeteners were extractable in acidic drugs extract and pesticide extract but they did not interfere in the analysis of drugs and pesticides. Therefore the screening methods usually used in forensic toxicological analysis for drugs and pesticides can be applied as such without any modification as the artificial sweeteners were not found to interfere.
