Abstract

Abstract A method of completely removing the volatiles in the headspace area of cans, bottles and other sealed containers which comprises inserting first and second penetrating means into the headspace of the sealed container without prematurely releasing the vacuum of the sealed container, passing a carrier gas into the headspace of the sealed container through said first penetrating means and removing the carrier gas and headspace volatiles from the sealed container through said second penetrating means for analysis.

Claims Analysis

Total Claims: 22
Claim 1
Independent Claim 108 words
A method of removing volatiles present in the headspace area of a sealed container without prematurely releasing the vacuum and said volatiles in said container comprising the steps of: (a) inserting a first penetrating means into the headspace area of a sealed container, (b) inserting a second penetrating means into said headspace area of said container, (c) passing an inert carrier gas into said headspace area of said container through said penetrating means, (d) withdrawing said inert carrier gas and volatiles from said headspace area in said container through said penetrating means other than the means utilized for the passing of said inert carrier gas into said container.
Claim 2
Independent Claim 108 words
A method of removing volatiles present in the headspace area of a sealed container without prematurely releasing the vacuum and said volatiles in said container comprising the steps of: (a) inserting a first penetrating means into the headspace area of a sealed container, (b) inserting a second penetrating means into said headspace area of said container, (c) passing an inert carrier gas into said headspace area of said container through said penetrating means, (d) withdrawing said inert carrier gas and volatiles from said headspace area in said container through said penetrating means other than the means utilized for the passing of said inert carrier gas into said container.
Claim 3
Dependent Claim 23 words
The method of claim 1 wherein the inert carrier gas is supplied at a flow rate of about 1 to about 100 cc/min.
Claim 4
Dependent Claim 20 words
The method of claim 1 wherein the inert carrier gas is selected from the group consisting of nitrogen and helium.
Claim 5
Dependent Claim 13 words
The method of claim 1 wherein the sealed container is submerged in water.
Claim 6
Dependent Claim 20 words
The method of claim 4 wherein the sealed container is submerged in water at a temperature of about 25° C.
Claim 7
Dependent Claim 18 words
The method of claim 1 wherein there is a complete removal of headspace volatiles in the sealed container.
Claim 8
Dependent Claim 14 words
The method of claim 1 wherein said first and second penetrating means are hollow.
Claim 9
Independent Claim 116 words
A method of removing and analyzing all the volatiles present in the headspace area of canned tuna without prematurely releasing the vacuum and said volatiles in said container comprising the steps of: (a) inserting a first penetrating means into the headspace area of said canned tuna, (b) inserting a second penetrating means into the headspace area of said canned tuna, (c) passing a carrier gas into said headspace area of said canned tuna through said penetrating means, (d) withdrawing said carrier gas and all the volatiles from said headspace area of said canned tuna through said penetrating means other than the means utilized for the passing of said inert carrier gas into said container for analysis.
Claim 10
Independent Claim 116 words
A method of removing and analyzing all the volatiles present in the headspace area of canned tuna without prematurely releasing the vacuum and said volatiles in said container comprising the steps of: (a) inserting a first penetrating means into the headspace area of said canned tuna, (b) inserting a second penetrating means into the headspace area of said canned tuna, (c) passing a carrier gas into said headspace area of said canned tuna through said penetrating means, (d) withdrawing said carrier gas and all the volatiles from said headspace area of said canned tuna through said penetrating means other than the means utilized for the passing of said inert carrier gas into said container for analysis.
Claim 11
Dependent Claim 22 words
The method of claim 8 wherein said carrier gas is supplied at a flow rate of about 1 cc/min. to 100 cc/min.
Claim 12
Dependent Claim 13 words
The method of claim 8 wherein said canned tuna is submerged in water.
Claim 13
Dependent Claim 20 words
The method of claim 8 wherein said canned tuna is submerged in water at a temperature of about 25° C.
Claim 14
Dependent Claim 22 words
The method of claim 8 wherein said canned tuna is centrifuged at 900 X G before insertion of said first penetrating means.
Claim 15
Dependent Claim 17 words
The method of claim 8 wherein hydrogen sulfide gas is removed from the headspace of canned tuna.
Claim 16
Independent Claim 156 words
A method of removing all the volatiles present in the headspace area of a sealed container for analysis without prematurely releasing the vacuum and said volatiles in said container comprising the steps of: (a) inserting a first penetrating means into the headspace area of a sealed container, (b) inserting a second penetrating means into said headspace area of said container, (c) passing a first inert carrier gas into said headspace area of said container through said penetrating means, (d) withdrawing said first inert carrier gas and all the volatiles from said headspace area of said container through said penetrating means other than the means utilized for this passing of said first inert carrier gas into said container, (e) condensing said inert carrier gas and volatiles, (f) heating said condensed first inert carrier gas and volatiles at a temperature sufficient to cause volatilization, (g) flushing said volatiles with a second inert carrier gas through a chromatography detector.
Claim 17
Independent Claim 156 words
A method of removing all the volatiles present in the headspace area of a sealed container for analysis without prematurely releasing the vacuum and said volatiles in said container comprising the steps of: (a) inserting a first penetrating means into the headspace area of a sealed container, (b) inserting a second penetrating means into said headspace area of said container, (c) passing a first inert carrier gas into said headspace area of said container through said penetrating means, (d) withdrawing said first inert carrier gas and all the volatiles from said headspace area of said container through said penetrating means other than the means utilized for this passing of said first inert carrier gas into said container, (e) condensing said inert carrier gas and volatiles, (f) heating said condensed first inert carrier gas and volatiles at a temperature sufficient to cause volatilization, (g) flushing said volatiles with a second inert carrier gas through a chromatography detector.
Claim 18
Dependent Claim 26 words
The method of claim 14 wherein the first and second inert carrier gases are supplied at a flow rate of about 1 to about 100 cc/min.
Claim 19
Dependent Claim 23 words
The method of claim 14 wherein the first and second inert carrier gases are selected from the group consisting of nitrogen and helium.
Claim 20
Dependent Claim 13 words
