Filed: 1962-07-05
Abstract: 971,385. Chromatography. TECHNICON CHROMATOGRAPHY CORPORATION. July 5, 1962 [July 13, 1961], No. 25770/62. Heading B1X. In a continuous chromatography apparatus including means for analysing the eluate from the chromatography column, means are provided for periodically interrupting the flow of the eluate to the analysing means and for concurrently permitting the flow of a standard liquid having a known constituent of known concentration to the analysing means in lieu of the eluate for standardization of the apparatus. As shown in Fig. 1, eluent from pump 22 enters chromatography column 12 through inlet opening 24, flows downwardly through the column for eluting the various zones of the chromatogram, and the resulting eluate is transmitted from outlet opening 26, by the aspirating action of pump 14, to colorimeter 16 where it is analysed and the results are recorded in the form of light transmission curves by multipoint recorder 18, The inlet opening 24 of the column is controlled by valve 28 which is operated by solenoid 30, and outlet opening 26 is controlled by a similar valve 32 which is operated by solenoid 34. A standard liquid is supplied to conduit 36, and the flow of the standard liquid through the apparatus is controlled by a normally closed valve 38 which is operated by solenoid 40. The flow of eluent to the column and the flow of eluate from the column is periodically interrupted by closing valves 28 and 32, and concurrently with the closing of these valves, valve 38 is opened to permit the passage of standard liquid to the apparatus in lieu of the eluate for standardization of the apparatus. If the apparatus is operating properly, the resulting curves from the standardization operation should indicate the same light transmittance values versus concentration previously established for the apparatus with respect to the standard liquid. If the curves differ from those previously established it indicates that the apparatus should be recalibrated or adjusted. The apparatus is controlled by an electric control circuit which includes a timer for controlling the eluate examining period of operation of the apparatus and another timer for controlling the period of operation of the standardization operation of the apparatus. The timers are connected to the analysing means in such a manner that operation of the timer controlling the standardization operation is prevented unless the response of the analysing means is above a predetermined value, e.g. above a light transmittance value of 85%.
