Description

The invention relates to instrumentation, structure, and can be used to record the results of homogeneous chromatographic analyzes from several analysis streams submitted for analysis according to the program.

The aim of the invention is to increase the visibility and facilitate the interpretation of the displayed information.

The drawing shows a block diagram of a multipoint recording device for a chromatograph.

The device contains a pulse former 1, an annular commutator circuit 2, a distributor 3 with analysis flows 4, a chromatograph 5, a recorder 6 with a synchronous motor 7 and a multipoint switch 8, two-input logic elements I 9, a programmer 10, a multi-input element OR 11, trigger 12 with separate inputs, as well as a pen mechanism 13, a digital printing electromagnet 14 and an electromagnetic clutch 15,

The operation of the device is as follows.

Selection and sequential connection to the chromatograph 5 of the analyzed streams 4, set on the programmer 10, is carried out according to a signal, which outputs the chromatograph 5 to the second input of the trigger 12 with separate inputs. In this case, the pulse shaper 1 starts impulses to the ring switching circuit 2, which causes a successive appearance at each of its outputs of a signal arriving at the corresponding inputs of the distributor 3, the multipoint switch 8 and the two-input logic element 9, When the corresponding two-input logic input element AND 9 signals coming from the output of the ring switching circuit 2 and from the programmer 10, from its output through the multi-input element OR 11 passes the signal to the first the trigger input 12 with separation inputs, and the latter stops the pulse shaper 1, the corresponding analysis flow 4 through the distributor 3 is connected to the chromatograph 5 for sampling for analysis, and in the multipoint switch 8 connected via the electromagnetic coupling 15 to the synchronous motor 7, the common output is switched from

Q Q, l,

about his insights. When the common output of the multipoint switch 8 is connected to its input, on which there is a signal received from the corresponding output of the ring switching circuit 2, the electromagnetic coupling 15 triggers and disconnects the multipoint switch 8 from the synchronous motor: 7, while in the recorder 6 a digit corresponding to the number is set the analysis stream connected to the chromatograph 5,

At the end of sampling, chromatograph 5 generates a signal for switching on an electromagnet of digital printing 14, which fixes the digit on the paper of the recorder 6, corresponding to the number of the analysis flow 4, And the separated components in chromatograph 5 are recorded by the recorder 6 in the form of a chromatogram. using the pen mechanism 13,

Upon completion of sampling, chromatograph 5 outputs a signal to the second input of trigger 12 with separate inputs, and the device repeats.

Thus, on the recorder's paper, the number of the assay stream from which the sample was taken and introduced into the chromatograph is printed, and as a result of the analysis of the selected sample, it is recorded as a chromatogram in continuous and easily decrypted form.
