Abstract
The present invention, which provides one kind, can effectively detect the method for determining 1,2,3- trichloropropane contents in electronic material.This method analyzes test with gas chromatography-mass spectrometry (GC-MS), and tested electronic material sample need to be extracted in preceding processing with temperature control type ultrasound bath oscillator.
Description
Technical field
The present invention relates to a kind of detection methods of 1,2,3- trichloropropane contents in effectively measurement electronic material, belong to electronics
Poisonous and harmful substance detection technique field in electric product.
Background technique
1,2,3- trichloropropane is one kind of SVHC European Union REACH concern substance, belongs to electric equipment products environmental pollution
One kind of object, for whether there is 1,2,3- trichloropropanes and 1 in electronic material, the content of 2,3- trichloropropanes is how many,
A kind of detection method is needed to detect.
Summary of the invention
For the content for needing to detect 1,2,3- trichloropropanes in electronic material, the present invention provides one kind can be with quantitative detection
The method of 1,2,3- trichloropropane contents in electronic material.
The present invention includes using 1,2,3- trichloropropanes in gas chromatography-mass spectrometry (GC-MS) test electronic material
Content and to associated electrical material sample pre-treatment when, are extracted with temperature control type ultrasound bath oscillator.
Detailed description of the invention
Attached drawing 1 is the operational flowchart of the embodiment of the present invention.
Specific embodiment
Embodiments of the present invention are once illustrated by specific specific example, those skilled in the art can be by specification institute
The content of announcement understands advantages of the present invention and effect easily.The present invention can also be subject to reality by other different specific examples
Apply or apply, details in this specification can also be based on different perspectives and applications, without departing from the spirit of the present invention into
The various modifications of row and change.
The operational flowchart of the embodiment of the present invention, as shown in Figure 1, weighing 1.0g sample in tool plug conical flask, accurately
To 0.0001g, 20mL methylene chloride is added and makees extract liquor, is extracted 1 hour at 60 DEG C of constant temperature in ultrasound bath, filter paper filtering,
Said extracted is repeated three times with methylene chloride again, each 10mL, combined extract, after the completion of extraction, by vial from water-bath
It takes out, extract liquor is concentrated into 2-3mL or so with Rotary Evaporators after being cooled to room temperature, is transferred in 100mL volumetric flask, with two
Chloromethanes is settled to scale.With 0.45 μm of PTFE membrane filtration to sample introduction bottle, content analysis is carried out with GC-MS.Using identical
Reagent, carry out blank assay at identical conditions, be reconfigured standard solution, with gas chromatography-mass spectrometry (GC-
MS) quantitative analysis after establishing standard curve, measures blank, sample solution, and the signal according to each sample is read, by standard song
Line checks in corresponding concentration.
In sample pre-treatments of the invention, the extractant of addition can also according to sample need to select respectively plus other reagents
(such as toluene).
Above-described embodiment is merely illustrative the principle of the present invention and its effect, and is not intended to limit the present invention.It is any
Those skilled in the art are modified and are changed without departing from the spirit and scope of the present invention, to above-mentioned implementation.Therefore,
The scope of the present invention, should be using the range of claims as foundation.
