Determination of the old mechanical and electrical products in the vinyl chloride
1 Scope
This standard specifies the old mechanical and electrical products in the residual vinyl chloride headspace gas chromatography mass spectrometry.
This standard applies to the determination of the old mechanical and electrical products in the residual vinyl chloride polymer material.
Principle 2
The sample vial is placed in a glass transition temperature above content using gas chromatography mass spectrometry chloride.
3 Reagents and materials
Unless otherwise specified, reagents were of analytical grade.
3.1 Methanol. chromatographically pure.
3.2 vinyl chloride standard solution. the commercialization of certified standard solution, 5000mg/L, using methanol as solvent, vinyl chloride purity of greater than
99.5%, refrigerated stored.
3.3 standard solution Ⅰ. accurate Pipette vinyl chloride standard solution 2mL to 100mL brown volumetric flask, constant volume of methanol, concentrated to give
Degree of 100mg/L of standard solution, refrigerated stored.
3.4 standard solution Ⅱ. accurate Pipette 1mL to 100mL standard solution Ⅰ brown volumetric flask, constant volume of methanol to give a concentration
Save as 1mg/L standard working solution Ⅱ, refrigerated in the dark.
4 instruments and equipment
4.1 Gas chromatograph with mass selective detector (MSD).
4.2 air injector.
4.3 micro syringe. 10μL, 50μL.
4.4 bottles. 20mL.
4.5 Analysis of balance. a sense of the amount of 0.1mg.
Step 5 Analysis
5.1 Determination
5.1.1 GC-MS analysis conditions
Because the test results depends on the instrument used, it is impossible to give general parameters chromatographic analysis. Using the following operating conditions are
It proved to be suitable for testing.
a) capillary column. DB-624 capillary column 1). 30m × 0.32mm × 1.80μm or equivalent person;
1) DB-624 is the trade name of the company provided by Agilent, this information is given for the convenience of users of this standard does not mean that the product identified
can. If other equivalent product has the same effect, you can use these equivalent products.
b) temperature program. Initial temperature 30 ℃ (held 3min), and then heating rate 20 ℃/min was raised to 100 ℃ (held
