Note.Meanwhile, it is to calculate time integration algorithm important evidence because it is relatively specific for long-time personal sampling, it is on-job
Industry health field has quite varied application prospect.
Pump-free type samplers are based on analyte under difference in chemical potential effect inside and outside sampler, with free diffusing (through expansion
Dissipate layer or permeable membrane) mode, the sampler of enrichment of analyte from environment.Pump-free type samplers are based on Fick diffusion laws
Design, diffusion coefficient and diffusion area of the sampling rate to measured matter in diffusion layer is directly proportional, is inversely proportional with diffusion length.
It follows that to expect the larger sampler of sampling flow it is necessary to trying increase diffusion area or reducing diffusion length.
The badge-type pump-free type samplers of report are the classes using more maturation, but predominantly uni-directional diffusion is sampled.
Utility model content
The utility model mainly by the sampler back side and is sampled the clothing point of people using supporting construction exclusive on shell
Separate and, reach two-sided penetrating effect, considerably increase the sampling flow of sampler, and can be changed by retaining shell
Carbon plate and filter membrane come cost-effective, reach the purpose of recycling.
The purpose of this utility model is to provide a kind of two-sided penetrating badge-type pump-free type air sampler, with preferable
Sampling efficiency, wide applicability and reusability.
A kind of two-sided penetrating badge-type pump-free type air sampler, including plastic seal box, sampler shell, hydrophobic filter
Film, fibrous activated carbon piece, collar folder；Sampler two ends outermost is plastic seal box, and plastic seal shell is buckled and adopted
The outside of sample device shell, the inwall of sampler shell is covered each by one layer of hydrophobic filter membrane, is all put per a piece of fibrous activated carbon piece
In the middle of the hydrophobic filter membrane of two panels；Sampler is taken out from plastic casing during sampling, plastic seal box is integrally placed at after the completion of sampling
Middle preservation.
The sampler is flat structure.
Contain 1-2 pieces activity carbon plate in described each pump-free type samplers；Dredged containing 2-3 in each pump-free type samplers
Water filter membrane.
The section diameter of the sampler enclosure packing material is 2-8cm, and thickness is 0.5-2cm, preferably diameter
It is 4cm, thickness is 1mm；The outside of the sampler shell has supporting construction, and it is 30-90 ° that angle is spaced between support, excellent
Choosing is 90 °；Aperture is provided with shell, to ensure its permeability.
A diameter of 2-8cm of the fibrous activated carbon piece, preferably 4cm, thickness is 0.5-3mm, preferably 1.5mm,
Quality is 10-100mg, preferably 35mg, using preceding closed preservation, is placed in 100-140 DEG C, at preferably 120 DEG C baking oven high temperatures
Reason 0.5-5 hours, preferably 2 hours, foil sealing was saved backup after activation, in being assembled and being ensured assembling process before sampling
Cleaning and complete.
Micropore size on the hydrophobic filter membrane is 0.1-1 μm, preferably 0.45 μm；The diameter of the hydrophobic filter membrane is 2-
8cm, preferably 4cm.
The plastic seal housing diameter is 2-8cm, preferably 5cm, and processes regular, with good sealing.
The beneficial effects of the utility model：Two-way penetrating shell mechanism is significantly increased to sampling efficiency, logical in absorption
Amount, sample stability aspect is attained by satisfied effect, and can by retain shell change carbon plate and filter membrane come
Recycling, it is cost-effective；Built-in fibrous activated carbon piece makees adsorbent, adsorption efficiency is had larger carrying compared with cocoanut active charcoal
Height, and being capable of most of volatile organic matters in collecting work place；The special supporting construction of its polytetrafluoro sampler shell
Whole sampler can be made two-sided penetrating, be a kind of benefiting our pursuits for novelty.The utility model is in terms of miniaturization, portability
With very huge potentiality, have in the application of the various fields such as occupational health, environmental monitoring to pump-free type samplers important
Meaning.
