Abstract

Abstract In a sample used to test the accuracy of an instrument designed to quantitatively analyze organic material from the optical characteristics of the material, a sealed container is filled with a mixture of ground quartz and the organic material to be analyzed in the instrument. A window is provided in the sealed container to permit irradiation of the mixture so that the instrument can perform a quantitative analysis on the mixture in the sealed container.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 83 words
In a standard test sample comprising a closed container including a window transparent to irradiation of a predetermined wavelength, the improvement wherein a mixture of organic material and a second material is in said container positioned against said window, said second material being impervious to water and transparent to said predetermined wavelength, said organic material being present in an amount effective to be analyzed by irradiation, said second material being present in an amount effective to resist migration of moisture in said mixture.
Claim 2
Dependent Claim 83 words
In a standard test sample comprising a closed container including a window transparent to irradiation of a predetermined wavelength, the improvement wherein a mixture of organic material and a second material is in said container positioned against said window, said second material being impervious to water and transparent to said predetermined wavelength, said organic material being present in an amount effective to be analyzed by irradiation, said second material being present in an amount effective to resist migration of moisture in said mixture.
Claim 3
Dependent Claim 14 words
A test sample as recited in claim 1, wherein said organic material is grain.
Claim 4
Dependent Claim 19 words
A test sample as recited in claim 1, wherein said wavelength is infrared and said second material is quartz.
Claim 5
Dependent Claim 24 words
A mixture as recited in claim 3, wherein said quartz is in the range of 25 to 75 percent by weight of said mixture.
Claim 6
Dependent Claim 15 words
A standard test sample as recited in claim 3, wherein said quartz is ground quartz.
Claim 7
Dependent Claim 22 words
A test sample as recited in claim 5, wherein said quartz is from 25 to 75 percent by weight of said mixture.
Claim 8
Dependent Claim 14 words

Claim 10
Dependent Claim 47 words
A mixture comprising particulate organic material and ground quartz, said organic material consisting of an agricultural product and being present in an amount effective to be analyzed by infrared irradiation, said ground quartz being present in an amount effective to restrict migration of moisture in said mixture.
Claim 11
Dependent Claim 47 words
A mixture comprising particulate organic material and ground quartz, said organic material consisting of an agricultural product and being present in an amount effective to be analyzed by infrared irradiation, said ground quartz being present in an amount effective to restrict migration of moisture in said mixture.
Claim 12
Dependent Claim 25 words
A mixture as recited in claim 9, wherein said ground quartz is in the range of 25 to 75 percent by weight of said mixture.
Claim 13
