Abstract

Abstract A device for handling porous solid matrixes (16) in analytic determinations of the type comprising at least one reaction step, which is performed in the very matrixes by absorption of a liquid phase therein, comprises a holder (1) and at least one matrix carrier (2), each of which can retain a matrix (16) while at the same time permitting liquid which surrounds the matrix carrier to substantially unobstructedly be absorbed by the matrix. The holder (1) is provided with at least one gripping body (11) projecting therefrom, each of which can detachably carry a corresponding matrix carrier (2), and at least one squeezing body (11), each of which can be pressed against the porous matrix for squeezing out liquid from the same.An analysis apparatus comprises such a handling device. the holder (1) of which is carried by a driving mechanism in the apparatus. which driving mechanism has driving means for both horizontal and vertical displacement of the holder (1), so that matrix carriers (2) earned by the same can be moved horizontally between adjacent liquid containers (29. 29. 301 and vertically down into and up from selected liquid containers.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 132 words
A device for handling porous solid matrixes (16) in analytical determinations of the type comprising at least one reaction step, which is carried out in the very matrixes by absorption of a liquid phase therein, characterized in that it comprises a holder (1) and at least one matrix carrier (2), each matrix carrier being arranged to retain a matrix (16) while permitting liquid which surrounds the matrix carrier to substantially unobstructedly be absorbed by the matrix, and in that the holder (1) is provided with a) at least one gripping body (11) projecting therefrom, each gripping body being arranged to detachably carry a corresponding matrix carrier (2), and b) at least one squeezing body (10), each of which can be pressed against the porous matrix for squeezing out liquid from the same.
Claim 2
Independent Claim 132 words
A device for handling porous solid matrixes (16) in analytical determinations of the type comprising at least one reaction step, which is carried out in the very matrixes by absorption of a liquid phase therein, characterized in that it comprises a holder (1) and at least one matrix carrier (2), each matrix carrier being arranged to retain a matrix (16) while permitting liquid which surrounds the matrix carrier to substantially unobstructedly be absorbed by the matrix, and in that the holder (1) is provided with a) at least one gripping body (11) projecting therefrom, each gripping body being arranged to detachably carry a corresponding matrix carrier (2), and b) at least one squeezing body (10), each of which can be pressed against the porous matrix for squeezing out liquid from the same.
Claim 3
Dependent Claim 50 words
A device according to claim 1, characterized in that each squeezing body (10) is attached to the end of a shaft (8) projecting from the holder (1), the corresponding gripping body (11) being carried by said shaft so that it can slide between the gripping body and the holder (1).
Claim 4
Dependent Claim 21 words
A device according to claim 2, characterized in that the gripping bodies (11) are spring biased against the squeezing bodies (10).
Claim 5
Independent Claim 31 words
A device according to any one of claims 1 to 3, characterized in that it comprises a device (4) for ejection of the matrix carriers (2) from the gripping bodies (11).
Claim 6
Dependent Claim 48 words
A device according to claim 4, characterized in that the holder (1) comprises a stationary part (3) and a movable part (4) which can be moved relative to the stationary part so as to contact the matrix carriers (2) for ejecting the same from the gripping bodies (11).
Claim 7
Independent Claim 32 words
A device according to any one of claims 1 to 5, characterized in that the matrix carriers (2) are detachably carried by the gripping bodies (11) by frictional engagement with the same.
Claim 8
Independent Claim 30 words
A device according to any one of claims 1 to 6, characterized in that each squeezing body (10) is connected to a suction conduit (21-23) provided in the holder (1).
Claim 9
Dependent Claim 68 words
A device according to claim 7, characterized in that the suction conduit comprises a manifold (21) provided in the holder (1), and a plurality of branch channels (23), corresponding to the number of squeezing bodies (10), said branch channels (23) connecting the manifold (21) with the respective squeezing bodies (10) and preferably being formed by inner cavities provided in the shafts (8) which carry the squeezing bodies (10).
Claim 10
Dependent Claim 115 words
An analysis apparatus for handling porous solid matrixes in analytical determinations of the type comprising at least one reaction step, which is carried out in the very matrixes by absorption of a liquid phase therein, characterized in that it comprises a handling device according to any one of claims 1 to 8, the holder (1) of which is carried by a driving mechanism in the apparatus, which driving mechanism has driving means for both horizontal and vertical displacement of the holder (1), so that the matrix carriers (2) which are carried by the same can be moved horizontally between adjacent liquid containers (29, 29', 30) and vertically down into and up from selected liquid containers.
Claim 11
Dependent Claim 33 words
An analysis apparatus according to claim 9, characterized in that it comprises a program unit for controlling the horizontal and vertical movements of the holder (1) according to a pre-selected path of movement.
