Process and apparatus for chemical analysis by liquid cromatography. |
摘要 |
<p>A process and an apparatus for performing analyses in liquid chromatography, by means of a pump capable of drawing a fluid and injecting it at high pressure, through at least a control valve, into a separation column. To obtain maximum precision as required by the analysis, before each analysis or each group of analyses, or with respect to each fluid used, a pump stroke is performed with the pump delivery side shut off in order to record and memorize the characteristics of compressibility of the fluid. These characteristics are kept into consideration in the subsequent operative stages to obtain an exactly constant delivery of the feed pump to the separation column.</p> |
