Description
Technical field
The present invention relates to air environment detection fields, wrap up in paper device more particularly, to a kind of test tube.
Background technique
It needs to capture gas when carrying out PM2.5 constituent analysis, dissolution extraction is carried out by different reagents later
Take out ingredient to be analyzed.ROS is a kind of initiation free radical, current study show that it is main of injury for causing human body
Source.Since ROS reactivity is higher, still using the content of ROS in artificial detection atmosphere, this is not only needed for traditional offline sampling
Put into a large amount of time and labour, and there is a problem of two it is more serious: one, different experiments analysis personnel's operating habit
It is had differences with experimental level, so that the comparativity for the data that different experiments personnel measure declines, or even can therefore summarize error
Conclusion accidentally.Two, ROS chemical property in part is active in Atmospheric particulates, the service life is shorter, and artificial detection time is longer,
So that the ROS that this part is unstable, the service life is shorter can not be measured and cause a large amount of losses of high activity ROS.Existing ROS exists
Line detection system also has that stability is poor, can not detect the defects of gaseous state ROS, it is difficult to carry out to the concentration level of ROS in atmosphere
Accurate measurement, therefore, it is difficult to the concentration levels to ROS in atmosphere accurately to be measured, to can not understand fully that it is anti-in Atmospheric Chemistry
The rule that becomes is transmitted and is returned in generation in answering.
Also, it is very sensitive to light due to the reagent particularity that detection uses, in order to guarantee the validity of detection and accurate
Property is it is necessary to guaranteeing the stabilization of reagent.Screening usually is reached using the outer layer that aluminium-foil paper is wrapped in test tube manually to the protection of reagent
The purpose of light.This method is suitble to carry out in laboratory, and with the maturation of detection technique, sample size to be detected also increases therewith
Add, the successional ingredient for capturing, analyzing pollutants in air only cannot be operated manually, be needed to improve efficiency to packet
The process for wrapping up in aluminium-foil paper improves.
Summary of the invention
