Lead Fast Testing Kit HMTK-Pb
Product Background:Lead is recognized as a highly hazardous environmental pollutant. The use of product with lead content exceeding the standard level causes many diseases. During the past years, the applications of lead in battery, electronics, petrochemical, paint and coating, ceramic and glass, rubber and plastics industries have resulted in wide range of lead pollution in family and working locations. Now, more and more regulations have been established to control the environmental problem of lead pollution, such as RoHS Directive of EU, the Act 65 of California in US, the Administrative Measure on the Control of Pollution Caused by Electronic Information Products in China, and etc. All these laws and regulations have respectively stipulated mandatory limits on lead content of products. The regular method of lead detection, which requires the test sample to be tested in a laboratory, is time wasting and expensive with complicated operation, and due to the damage to the test piece, only sample test is possible. According to the above situations, we developed the lead fast testing reagent cooperated with ITS CHEMICAL, INC. at 2006, it can carry on the fast screening test to the lead ion.
Product Theory: Use the specific high-sensitivity reagents, it can generate chemical reaction with lead ion and turn to bright pink.
Product Use:It can determine surface lead content of various material, such as solder, paints and coatings, ceramic ware, alloy, toys, jewelry, electronic products, clothing accessories etc.
Product Features:
1. Fast detection, easy to operate, cost effective, obvious results, portable design, safe and non-toxic, nondestructive testing.
2. It can be used for qualitative testing and pre-detection of lead content on the surfaces of various materials.
General Method of Using:
1. Clean the dust and dirt from the surface of the material to be tested.
2. Insert the swab into the powder of the lead fast testing reagent in vial A and stir several times, then pull out the swab（the surface of the swab attached with some powder）.
3. Drip 1- 2 drops of lead fast testing reagent from vial B onto the above mentioned swab (if the soaked swab turns light yellow on the local area, the reaction is activated and then the activated swab shall be used within 2 minutes).
4. Rub the swab several times against the surface of material to be tested. If the swab appear bright pink color , lead present on the surface of the material at hazardous level(any pink colors indicate the presence of lead and the thicker of the color appeared, the higher the lead content is , and the pink color will not fade within several hours); If only yellow or other colors but not pink color appeared on the swab, lead is not present on the surface of the material to be tested or not up to the hazardous level(yellow and other colors will fade gradually).
Note: Prior to testing, the products to be tested shall be separated into basic units. Both the decoration layer and substrate will be tested respectively for the material surface with decoration layer. Since the lead content on the surface of the material may not be evenly distributed, it is recommended to test different areas of same material—more than 5 different areas is preferred.
The Energization method(Specific condition)：
Since today’s regulation is increasingly strict with the lead content controlling, with a prevailing requirement lower than 1000 ppm, 600 ppm or even lower. In order to detect the micro lead content of the material to be tested, our company has introduced a innovative method of increasing the sensitivity of the testing through energization with 9V batteries. This method is used for the testing of metallic material. The procedures are as follows:
1. Sand the surface of the material to be tested with sandpaper, then wipe it clean with alcohol, to minimize the testing error.
2. Also wipe clean the negative pole（with black wire）of the battery with alcohol.（Always wipe it clean before every test.）
3. Drip a droplet of reagent (3mm in diameter) from Vial B onto the surface of the material to be tested.
4. Contact the positive terminal (with red wire) of a 9V battery with the material to be tested, the negative terminal (with black wire) shall contact with the surface of the droplet(Do not contact the surface of the material) Energize the material for at least 30 seconds.
5. Dip the swab into Vial A and stir several times to attach some powder on the tip.
6. Dab the swab with powder at the energized droplet.
7. If a pink or light pink color appeared at the swab, lead present at the surface of the material to be tested. A lead content as low as several hundred ppm can be detected this way.
Note: The accuracy of the testing varies with the size of the droplet，the sufficiency of the electricity，time of energization，ingredient and surface condition of the material, so every test shall be done in a consistent way to find the pattern. The testing data of different material are yet to be verified through further testing. All wires and swabs used must be lead free.
Cautions:
1. This Vial B is of weak acidity. If eye contact or skin contact occurs, rinse with water.
2. For more accurate lead content data, please send the test piece to a specialized laboratory to test.
3. For detailed description of common used material, see the application examples.
Liability:The manufacturer and its authorized agents are free from any liabilities due to taking by accident of children and misunderstanding or misuse of the users. If nickel contamination is suspected based on this test, consult an analytical testing laboratory and take the necessary precautions.
