Description
Technical field:
The utility model relates to a kind of ultrasonic atomization liquid injector.
Background technology:
Organism is often referred to the compound of carbon elements, or hydrocarbon and their derivative is generically and collectively referred to as organism, is the abbreviation of organic compound.Organism in the water has volatility and non-volatile, and up to the present the whole world has determined 2221 kinds of organic compounds in water.The U.S. sanitary study portion identifies 767 kinds of organic chemical pollutants in U.S.'s water body, wherein 109 kinds is carcinogenic, short cancer and mutagenic matter.In recent years, China also attracts great attention to the organism in the water, once detects more than 700 kind of organism in the river of the Huangpu in Shanghai; Draw Luan Shuizhong in Tianjin, once detected 15 kinds of volatile organic matters and other organism of kind more than 200; Duan Shuizhong records 317 kinds of organic compounds with the GC/MS method in river, Jilin, second Song Hua River.In the organism that these have been found, wherein confirmed carcinogenicly have 20 kinds through biology demonstration; Suspect carcinogen has 24 kinds; Short cancer thing or co-carcinogen have 18 kinds; AMES test mutagenic matter has 47 kinds.Therefore, the organism testing is significant in the water.Volatile because of volatile organic matter, difficulty extracts, thereby very easily is interfered in pre-treatment, and the impact analysis result is so the input mode of volatile organic matter instrumental analysis is head space and purging two big classes in the water commonly used at present.But headspace sampling is difficult to obtain reappearance preferably, and the purge time is long, can impact analysis the efficient of work and data ageing.Nonvolatile organic compound pre-treatment workload is big, very easily is interfered the extractant contaminated environment in the process.So all there are drawback to a certain degree in organism instrumental analysis pre-treating method and sample injection method in the water commonly used at present.
Summary of the invention:
The purpose of this utility model provides in a kind of shortening water organism analysis time, performance fast detecting effect ultrasonic atomization injector in the water pollution accident.The purpose of this utility model realizes by following structure: the utility model is a kind of ultrasonic atomization liquid injector, partly constitute by main part and ultrasonic atomization, the top of main part is provided with the checkout equipment interface, the bottom of main part is a ultrasonic atomizatio part interface, the sidewall communication with carrier gas arm of main part, ultrasonic atomizatio is partly with the main body connector, the ultrasonic transduction sheet is installed main body connector bottom, the ripple atomised part is provided with temperature control equipment and power supply coupling part, main part partly is to coincide up and down with ultrasonic atomizatio and is connected, be tubular structure, carrier gas is propped up tube inlet upwards, the top of ultrasonic atomizatio part links to each other with the main part interface, and the ultrasonic atomizatio partial interior is embedded with ultrasonic atomization transducing sheet.The utility model belongs to organism sample analysis pretreatment technology field in the water, and this equipment is at the experimental stage at present, has obtained good experiment effect; Its objective is the pre-treatment process of simplifying, shorten in the water organism analysis time, be widely used in environmental monitoring, fields such as food and medicine detection, especially performance fast detecting effect in the water pollution accident.The utility model can guarantee detection accuracy, simplify the step of organism detecting instrument pre-treatment in the water, thereby shorten the time of detecting, improve treatment effeciency, can be widely used in the pre-treatment of volatility and nonvolatile organic compound detecting instrument in the water, favorable reproducibility, and can improve the sample detection limit.The carrier gas of the utility model main part is propped up tube inlet upwards, and outlet has effectively been avoided sample liquid to overflow downwards and flow backwards.Ultrasonic atomizatio part top links to each other with the main part bottom, inside is embedded with ultrasonic atomization transducing sheet, this transducing sheet can convert electric energy to machinery shake can, transducer is applied resonant electrical signals makes transducer produce the vibration of ultrasonic wave of frequency range at 1-3MHZ, liquid solution sample in the main body is atomized into the aerosol particles of diameter 1-10 μ m, for making atomization quantity stablize ultrasonic atomizatio thermostat is arranged partly, the gasoloid that is mixed in the body cavity enters the detection adsorbent equipment under the carrier gas effect.Enter the sample that detects adsorbent equipment and present gas, two kinds of forms of liquid: a kind of is the gaseous organic substance that the liquid aersol particulate volatilizes; Another kind is to contain organic liquid particle.Wherein moisture is processed in adsorbent equipment fall after, remaining organism enters detection system.Like this, volatile organic matter and nonvolatile organic compound have all entered adsorbent equipment in the water.Thereby reach the purpose that single injected sampling detects volatile organic matter and nonvolatile organic compound simultaneously.Significantly improve organic amount of analysis in the water sample, improved pre-treatment efficient, shortened analysis time; For the organism of difficulty volatilization, the heavy work of then having saved extraction process got rid of the interference that brings owing to extraction, and analysis efficiency improves greatly.
Detect pre-treating method with other organism and compare, the utlity model has the advantage of following uniqueness:
1) improved the volatile organic matter detection sensitivity;
2) realized that single injected sampling detects volatility and nonvolatile organic compound simultaneously;
3) simple to operate, the treatment effeciency height;
4) favorable reproducibility; The sample detection limit is low.
In a word, the purpose of this utility model is to improve organism detection efficiency in the water, shortens detection time, and get rid of extraction and wait of the interference of pre-treatment process analysis result, be organic detection injector in a kind of widely used water.
