According to the recent demand for our customers, EST laboratories to strengthen the PAHs (polycyclic aromatic hydrocarbons) testing. PAHS testing for, EST do about that.

Polycyclic aromatic hydrocarbons (PAHs)

I. Introduction

PAHs, polycyclic aromatic hydrocarbons name. Oil, coal and other fuels and wood, combustible gases in the incomplete combustion or high temperature conditions generated by a class of harmful substances, often present in petrochemical products, rubber, plastics, lubricants, anti-rust oil, incomplete combustion of organic compounds and other substances in the environment, one of the most important carcinogens, PAHs include 16 kinds of similar material.

In the environment, full of organic pollutants in various locations, polycyclic aromatic compounds (PAHs) for its bulk, and some have been proven to have cancer and mutagenicity of the human body. Source of PAHs include: algae or bacteria on the biosynthesis, forest fires, volcanic eruptions, as well as coal-fired power plants, incineration of garbage dump site, steam locomotives, such as with the factory exhaust. Many of the types of PAHs, of which 16 kinds of compounds in 1979 by the U.S. Environmental Protection Agency (US EPA) listed in the tube.

Second, the background

A few days ago, China produced a large number of power tools has been detected in Germany, exceeded the value of PAHs, more than 80 million U.S. dollars worth of goods were detained by German customs at the port. Germany is a core member of the European Union, so their influence soon spread to the entire European Union. At the same time, most of the technical standards of the European Union from Germany, once the new standards established by the PAHs, Britain, France and even the United States will follow up to that time, China's exports of electric tools and development of enterprises will face more severe challenges.

Third, the sample split test PAHs

Samples for the final resolution of a single homogeneous material and color material. This principle should be for each sample to calculate the material needed to test the quantity and pricing of each material should be a single material measured the content of 16 kinds of PAHs.

PAHs detection range

1 electronics, electrical products, such as analysis of consumption.

2 battery materials, welding consumables and other materials analysis ....

3, rubber, plastic products, automotive plastic, rubber parts of cadmium, lead and other heavy metal content analysis.

4 food packaging materials, toys, container stripping analysis of heavy metal material.

5 Analysis of organic compounds, metal ions.

6 organic solvents, aqueous solutions of anionic analysis.

7, paint, dye stripping analysis of heavy metals.

8 fluorine, chlorine, nitrate, sulfate, etc. ....

9, material composition analysis.

Analysis of 10 unknown samples (please contact).

Polycyclic aromatic hydrocarbons:

German: Polyzyklischer Aromatischer Kohlenwasserstoffe (PAK)

English: Polycyclic Aromatic Hydrocarbons (PAHs)

A total of more than 100 kinds of chemical structures of the general term, PAHs commonly contain 16 kinds of polycyclic aromatic hydrocarbons:

1 Naphthalene Naphthalene

2 Acenaphthylene Acenaphthylene

3 Acenaphthene Acenaphthylene

4 Fluorene Fluorene

5 Phenanthrene Philippines

6 Anthracene Anthracene

7 Fluoranthene Fluoranthene

8 Pyrene Pyrene

9 Benzo (a) anthracene Benzo (a) anthracene

Qu 10 Chrysene

11 Benzo (b) fluoranthene benzo (b) fluoranthene

12 Benzo (k) fluoranthene benzo (k) fluoranthene

13 Benzo (a) pyrene Benzo (a) pyrene

14 Indeno (1,2,3-cd) pyrene benzene indene (1,2,3-cd) pyrene

15 Dibenzo (a, h) anthracene Dibenzo (a, n) anthracene

16 Benzo (g, hi) perylene benzo (ghi) North (inlay Binaphthol benzene)

Characters: pure PAH is usually colorless, white, green or pale yellow solid

Source: incomplete combustion of organic matter, coal / oil / gas / tobacco / barbecue

Charcoal, oil, wood distillate oil, tar, drugs, dyes, plastics, rubber, pesticide

Engines, generators produce PAHs

Polycyclic aromatic hydrocarbons of the material that may exist

Charcoal, oil, wood distillate oil, tar (natural)

Drugs, dyes, plastics, rubber, pesticides (human)

Lubricants, from film, capacitor electrolyte, mineral oil, tar (man-made)

Pesticides, fungicides, mosquito coils, smoke, gasoline resistance coagulant (human)

Harmful polycyclic aromatic hydrocarbons

Strong carcinogen

Easily lead to skin cancer, lung cancer, upper digestive tract cancer, arteriosclerosis, infertility
