An outer jacket casing, the inner tube wall of this outer jacket casing is distributed with the second screw thread matched with above-mentioned first screw thread, its thread bush is connected on above-mentioned interior cylinder base, and offers exhaust hole on top of this;
And one for separating of, measure the gas chromatograph of concrete gas and vapor permeation composition;
Wherein, the exhaust hole of above-mentioned outer jacket casing is tightly connected mutually by the gas access of air shooter with gas chromatograph.
Above-mentioned gas chromatograph is in oil, chemical industry, biological chemistry, medical and health, food industry, environmental protection
Etc. aspect application very wide.It is except for quantitatively and except qualitative analysis, can also the physicochemical constant such as the partition factor of working sample on Stationary liquid, activity coefficient, molecular weight and specific surface area and carry out analysis detection to each component in mixed gas.It is a kind of existing conventional equipment, and therefore applicant seldom describes in detail it at this.
Above-mentioned middle provided a kind of pick-up unit detected for ambient soil, interior cylinder base in its structure and noose form a volume chamber at the outer jacket casing of its outside, and heating pole is distributed with in interior cylinder base, after holding soil to be detected in above-mentioned volume chamber, above-mentioned heating pole work is to this soil heating to be detected, the temperature of soil to be detected is made to increase, organic contaminant now in this soil to be detected one by one or synchronous start volatilization, such as agricultural chemicals, trichloroacetaldehyde, palycyclic aromatic, polychlorinated biphenyl, oil, methane etc., the exhaust hole that above-mentioned mixed gas is put by urceolus, gas chromatograph is entered to again through air shooter, this gas chromatograph is analyzed each component in mixed gas, detect, thus finally determine the kind of the organic contaminant in soil to be detected.
As further technological improvement, the power lead of above-mentioned heating pole is in series with the frequency modulation system for controlling power supply output frequency.
" frequency modulation " in above-mentioned frequency modulation system is that refer to amplitude is constant, the modulation system that the frequency of carrier signal changes with debug signal changes in amplitude position, and the whole modulating system that have employed above-mentioned principle is then the common practise of those skilled in the art.
Adjust power supply output frequency by frequency modulation system in above-mentioned further Technological improvement plan, the heating pole in the utility model can be worked under setpoint frequency, ensure its job stability and validity; Meanwhile, user, by the occurrence of adjustment setpoint frequency, realizes heating pole heating work in each frequency band Power supply situation, thus coordinates the firing rate requirement of various soil better, ensure the validity of this soil organic contamination detection architecture.
A kind of pick-up unit detected for ambient soil that the utility model obtains, it can accurately and the kind of effective detection organic contaminants in soil to be detected, and testing result is relatively accurate.
