Abstract
Abstract In a sorption sheet (1) for sorbing a plurality of discrete samples that simultaneously emit photons or beta particles, the emission thereof to be individually monitored, barriers (2) of a photon and/or beta particle attenuating material extend through at least a portion of the thickness of the sheet (1) which is known per se, to prevent cross-talk between the samples when monitored. The barriers are produced by soaking a liquid photon and/or beta particle attenuating material in a pattern of lines through at least a portion of the thickness of the sheet, whereupon that material is dried and/or cured.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
78 words
In a sorption sheet for sorbing a plurality of discrete samples that simultaneously emit photons or beta particles, which in contact with a scintillant cause an indirect emission of photons wherein the photon emission from the individual samples is to be monitored, where the improvement comprises barriers of a photon and/or beta particle attenuating material extending through at least a portion of the thickness of the sheet which substantially attenuates optical cross-talk between the samples when so monitored.
Claim 2
Dependent Claim
78 words
In a sorption sheet for sorbing a plurality of discrete samples that simultaneously emit photons or beta particles, which in contact with a scintillant cause an indirect emission of photons wherein the photon emission from the individual samples is to be monitored, where the improvement comprises barriers of a photon and/or beta particle attenuating material extending through at least a portion of the thickness of the sheet which substantially attenuates optical cross-talk between the samples when so monitored.

Claim 19
Independent Claim
130 words
A method for substantially attenuating optical cross-talk in monitoring a sample on a sorption sheet for sorbing a plurality of discrete samples that simultaneously omit photons or beta particles, which in contact with a scintillant cause an indirect emission of photons, wherein the photon emission from the individual sample is to be monitored, comprising providing barriers of a photon and/or beta particle attenuating material extending through at least a portion of the thickness of the sheet for the plurality of discrete samples; sorbing said plurality of discrete samples within said barriers on said sorbtion sheet; contacting said sorption sheet which is so sorbed with a scintillant, and monitoring the individual sample under conditions such that optical cross-talk is substantially attenuated in comparison to the corresponding sorbtion sheet without said barriers.
Claim 20
Independent Claim
130 words
A method for substantially attenuating optical cross-talk in monitoring a sample on a sorption sheet for sorbing a plurality of discrete samples that simultaneously omit photons or beta particles, which in contact with a scintillant cause an indirect emission of photons, wherein the photon emission from the individual sample is to be monitored, comprising providing barriers of a photon and/or beta particle attenuating material extending through at least a portion of the thickness of the sheet for the plurality of discrete samples; sorbing said plurality of discrete samples within said barriers on said sorbtion sheet; contacting said sorption sheet which is so sorbed with a scintillant, and monitoring the individual sample under conditions such that optical cross-talk is substantially attenuated in comparison to the corresponding sorbtion sheet without said barriers.
