FAQ

Can ROHS testing instruments test metal elements?

ROHS detection instrument is a professional equipment used to detect whether electronic components, household appliances, toys and other products contain harmful substances. These harmful substances may pose a long-term threat to humans and the environment, so the application of ROHS detection instruments is of great significance.

The answer to the question of whether ROHS detection instruments can test metal elements is affirmative. Because the scope of ROHS testing not only includes harmful substances, but also includes the detection of metal element components in qualified products. These metal elements include lead, cadmium, mercury, etc., which are widely used in product manufacturing. Although these elements are necessary, excessive use poses great harm to human health and environmental protection. Therefore, the emergence of ROHS detection instruments has brought great convenience to our detection of metal elements.

Which is the best gas chromatograph?

Gas chromatograph is a commonly used analytical instrument, which is widely used in chemistry, biology, medicine and other fields. However, there are many gas chromatograph brands on the market, and the prices are far from the same, making it difficult to choose. So, which gas chromatograph is better?

First of all, we need to understand the basic principles and performance indicators of gas chromatographs. Gas chromatograph uses samples to evaporate into a gaseous state at high temperatures, separate them by column, and then detect the degree and content of different components by detectors. Common performance metrics include resolution, sensitivity, linear range, repeatability, and more.

When choosing a gas chromatograph brand, we can consider the following aspects:

1. Brand awareness and word of mouth. Well-known brands usually have high technical strength and after-sales service guarantee, and have a better reputation.

2. Technological innovation and R&D capabilities. Gas chromatograph technology is constantly updated, and brands with strong R&D capabilities and technological innovation capabilities are more competitive.

3. Product performance and price. The performance and price of different brands of gas chromatographs vary greatly, and you need to choose according to your actual needs and budget.

4. After-sales service and technical support. Various problems may occur during the use of the gas chromatograph, and after-sales service and technical support can solve the problem in time to ensure that the instrument is running.

Which is the best service provider for RoHS spectrometers?

RoHS spectrometer is an instrument used to detect harmful substances in products. It can detect whether products contain lead, mercury, cadmium, Hexavalent chromium and other harmful substances to ensure human health and environmental safety. So, which one is the best service provider for RoHS spectrometers?

Firstly, we need to understand the basic principles and detection methods of RoHS spectrometers. RoHS spectrometer is an instrument based on the principle of spectral analysis, which can determine whether a sample contains harmful substances by analyzing the elements and compounds in the sample. The detection method of RoHS spectrometer is generally X-ray fluorescence spectroscopy (XRF).

What instruments are used to detect RoHS in electronic and electrical products?

RoHS (Restriction of the Use of Certain Hazardous Substances Directive) is a regulation established by the European Union aimed at limiting the content of harmful substances used in electronic and electrical products. These harmful substances include lead, mercury, cadmium, Hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers. To ensure product compliance with RoHS regulations, specific instruments need to be used for testing.

RoHS testing instrument is a device specifically designed to detect the content of harmful substances in electronic and electrical products. These instruments can detect the content of lead, mercury, cadmium, Hexavalent chromium, polybrominated biphenyls, Polybrominated diphenyl ethers and other harmful substances in products. RoHS test instruments are usually tested with X-ray fluorescence (XRF).

What is ROHS testing?

ROHS testing, full name Restriction of Hazardous Substances testing, refers to the testing of the content of specific hazardous substances in electrical and electronic products and wire and cable products to ensure that the products comply with relevant regulations and standards, thereby protecting consumers and the environment from harmful substances.

The origin of ROHS testing can be traced back to the European Union's Restriction of the Use of Certain Hazardous Substances Directive (RoHS Directive) issued in 2003, which requires companies to limit the content of harmful substances such as lead (Pb), mercury (Hg), cadmium (Cd), hexavalent chromium (Cr6+), polybrominated biphenyls (PBB) and polybrominated diphenyl ethers (PBDE) in electrical and electronic products and wire and cable products sold in the European market, and requires enterprises to test the content of their products.
