Please never convert or downsample vector-type graphics (all kinds of chemical formula drawings, for example ChemDraw® files) into pixel-type graphics (PC file extensions like tif, jpeg, bmp) unless you have good reasons to do so. If such conversion should be unavoidable, please make use of the high-quality (i.e. lowest data compression) setting in your graphics software. It is better to submit the original data or, alternatively, print directly into PDF. Õâ¸öChemDrawÎļþ²»ÄÜ´æΪTIF¸ñʽÂð£¿
The resolution in the final data should be about 300 dpi for halftone graphics without sharp details like lines and letters. Õâ¸öwithout sharp details like lines and lettersÊÇʲôÒâ˼ÄØ£¿
1. The authors point of that several earlier works (refs. 14-18) on xanthine detection have some issues, but do not discuss what these issues are. The authors must briefly discuss these and then highlight how their present work addresses the limitations faced by earlier works. µÚ¶þ¾ä»°ÊÇʲôÒâ˼ÄØ£¿
The authors should comment on why their system demonstrates such impressive selectivity even after being exposed to easily oxidable interferents like ascorbic and uric acid at such high detection potential (+0.9V) »¹ÓÐÕâ¾ä»°µÄÒâ˼¡£ |
