Abstract
The invention discloses a kind of gas of detection, including column, base, rotary round table and tabletting bar, the column is arranged on base one end, the rotary round table is rotatably installed on base, the tabletting bar includes L-type bar and rubber ends, the L-type bar is movably arranged on column, and height is adjusted on column, and the rubber ends are arranged on the end face of L-type bar, for compressing mirror, the present invention is simple in construction, is all detachable design, no matter stores or use, all extremely save space, it is simple to operate, use efficient, facility.
Description
Technical field
The invention belongs to the technical field of fixture, specially a kind of gas of detection.
Background technology
Expiration detector is the product of modern measure helicobacter pylori systems technology.Expiration sample detecting high sensitivity, inspection
Also expiration detector very of new generation is high for extracting rate and coincidence rate, patient's no pain, is a kind of detection pylorus spiral shell most welcome by patient
The method of bacillus.
Expiration detector needs to be detected before dispatching from the factory, and a kind of qualified detection gas, undoubtedly improves testing result
Reliability.
The content of the invention
It is an object of the invention to provide a kind of gas of detection, the reliability of testing result is improved.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
A kind of gas of detection, including spirit and sample gas, the spirit include CO2And N2, CO2Concentration (mol/mol) is
2.95-3.05%, N2For Balance Air, the sample gas bag includes12CO2、13CO2 and N2, CO2Concentration (mol/mol) 2.95-3.05%
,13CO2Prepare according to a certain percentage, N2For Balance Air.
Further, in the spirit13CO2Concentration is (1.18-1.69) × 10-6mol/mol.
Further,13CO2Calibrating gas DOB values are 3.5-5.0 (‰).
Further, it is described13CO2Concentration is about (0.51-1.01) × 10-6mol/mol.
Further,13CO2Calibrating gas DOB values are 1.5-3.0 (‰).
Further, pressure >=0.1Mpa is kept.
The beneficial effects of the invention are as follows：
The reliability of testing result is improved, is prepared simply, storage is convenient, and cost is low.
Embodiment
Embodiments of the invention are described in detail below, but what the present invention can be defined by the claims and cover
Multitude of different ways is implemented.
Embodiment one：
A kind of gas of detection, including spirit and sample gas, the spirit include CO2And N2, CO2Concentration (mol/mol) is
2.95-3.05%, N2For Balance Air, the sample gas bag includes12CO2、13CO2 and N2, CO2Concentration (mol/mol) 2.95-3.05%
,13CO2Prepare according to a certain percentage, N2For Balance Air.
Now provide two kinds13CO2Preparation program.
Scheme one：In the spirit13CO2Concentration is (1.18-1.69) × 10-6mol/mol,13CO2Calibrating gas DOB values
For 3.5-5.0 (‰).
Scheme two：It is described13CO2Concentration is about (0.51-1.01) × 10-6mol/mol,13CO2Calibrating gas DOB values are
1.5-3.0(‰)。
Confirm it is pointed out here that DOB values calculate：
In spirit sample13In C abundance=spirit sample13C concentration/(in spirit sample13C concentration+spirit sample
In12C concentration)
In sample gas sample sheet13In C abundance=sample gas sample sheet13C concentration/(in sample gas sample sheet13C concentration+sample gas sample sheet
In12C concentration)
DOB=is (in sample gas sample sheet13In C abundance-spirit sample13C abundance)/13C natural abundance * 1000
1)13C natural abundance=0.0112372；
2) spirit is12CO2Calibrating gas；Sample gas is13CO2Calibrating gas.
Gas can not be used up in gas cylinder, and residual compression must answer >=0.1Mpa.
The embodiments of the present invention described above are not intended to limit the scope of the present invention, any in the present invention
Spirit and principle within the modifications, equivalent substitutions and improvements made etc., should be included in the claim protection model of the present invention
Within enclosing.
