Frequently, in conducting such analyses, it is desirable to direct a plurality of portions of a sample into a plurality of analyzing columns or it may be desirable to direct a plurality of eluted portions of a sample being analyzed into a plurality of cumulating columns from which the portions can be subsequently recovered for further detailed analysis. The valve of the present invention provides a means for collecting such a plurality of samples.
According to the apparatus of this invention there is provided a valve comprising an inlet, a distributor, a conduit in open communication between said inlet and said distributor and a plurality of conduits in open communication between the distributor and a plurality of outlets opening from the valve.
The valve of the present invention is an improvement over multiport valves of the prior art because it embodies a first upper portion of comparatively small diameter to provide for the routing of the sample into any of a plurality of flow paths with a minimum opportunity of sample loss and it employs a second lower portion of a comparatively larger diameter to provide a sufficient area for the attachment of a plurality of columns to the plurality of conduits leading from the valve into the columns.
The apparatus of this invention will be more easily understood if explained in conjunction with the attached drawings in which FIG. 1 is a view of the valve in elevation;
FIGS. 2 through 9 are views of several of the individual elements comprising the valve; and,
FIG. 10 is a schematic diagram illustrating one flow pattern through the valve.
The apparatus of this invention will be described in terms of a preferred embodiment adapted for positioning in conjunction with a plurality of chromatographic columns, for example, six in number.

The column plate, column gasket, mounting plate, stator gasket and stator are indexed in predetermined positions and maintained in fixed positions by means of suitable bolting. The rotor and rotor cap are positioned as a movable entity in relation to the aforementioned elements and held in leak-proof arrangement relative thereto by means of the spring and spring plate.
The sample takes the flow path shown schematically in FIG. 10.
The sample is introduced into an inlet in mounting plate and flows through the mounting plate into the column gasket which acts to channel the sample into the proper conduit.

Rotation is effected through the motor to turn the rotor shaft which turns the rotor cap and rotor to any preselected position such that material flowing upwardly through the valve can be caused to flow in a preselected path down through the valve and into a preselected column affixed to the column plate.
It will also be seen that not only can a plurality of samples be introduced into a plurality of columns but a plurality of samples can be stored in the stator-stator gasket section of the apparatus upon suitable indexing, these samples being recovered from various cuts separated in any of the plurality of chromatographic columns or being introduced into the selector valve and stored therein for subsequent usage.
Simultaneously therewith, there can be contained within the valve, between the rotor and the mounting plate, in any selected channel 68, as shown in FIG. 10, another sample which, after entrapment therein, can be introduced into any of the plurality of columns affixed to the base of the column plate.
It will be appreciated that the various parts described can be adapted with one or more apertures to facilitate assembly and subsequent indexing of the various parts in sequential flow arrangement, any flow arrangement being selectable upon integration of the movements of the various parts as effected by the turning of the motor shaft in relation to the cams and micro-selector switches.
For example, in one embodiment of the invention the valve described has been used as a 12 port-l2 position rotary switching valve, the valve being constructed to switch any or none of six chromatographic columns into a system. Six of the valve positions are available to switch the column into the system with the six alternate valve positions being employable to bypass all columns. In this operation the valve can collect, store and introduce samples into the columns and can similarly collect, store and reintroduce component cuts from original samples.
It will be evident from the foregoing that various modifications can be made to the method of this invention. Such are considered, however, to be within the scope of the invention.
What is claimed is:
1. An apparatus comprising:
a. an inlet;
b. a movably-positionable distributor comprising a first circular grooved channel in a rotatable plate, said first circular grooved channel in direct contact with a channel from said inlet, said first circular grooved channel having a second channel extending therefrom whereby by rotation of said plate registry can be maintained with any one of a plurality of openings located at the same direction in the same direction away from this first circular grooved channel;
c. a first plurality of openings, each of said openings connected to a conduit leading from said distributor; and
d. a first plurality of conduits each connected to one of said openings.
2. The apparatus of claim 1 in which said plurality of conduits are individually adapted for the insertion thereinto of a chromatographic column.
3. The apparatus of claim 1 in which said distributor is positionable by motor means.
4. The apparatus of claim 3 in which said motor means is controlled by selector switches.
5. The apparatus of claim 1 in which said apparatus comprises a mounting plate and a column plate.
6. The apparatus of claim 5 in which said inlet is positioned in said mounting plate and said first plurality of conduits open from said column plate.
7. The apparatus of claim 6 in which a second plurality of conduits provide open communication through said mounting plate and opens from said mounting plate.
8. The apparatus of claim 7 comprising:
a. an outlet;
b. said movably-positionable distributor comprising a second circular grooved channel in said rotatable plate, said second circular grooved channel in direct contact with a channel to an outlet, said second circular grooved channel having a second channel extending therefrom whereby by rotation of said plate registry can be maintained with any one ofa second plurality of openings located at the same distance in the same direction away from the second circular grooved channel; and
c. a second plurality of openings, each of said openings connected to one of said second plurality of conduits.
9. The apparatus of claim 8 in which chromatographic columns are positionable between said plurality of conduits opening from said valve and said second plurality of conduits opening from said mounting plate.
10. The apparatus of claim 1 in which said apparatus is adapted with storage conduits.
