Quality analysis and testing

OCEAN CHEMICAL since its establishment has adhered to the quality policy of "fair and objective, scientific and accurate, comprehensive and orderly, quality and efficient",always strive for high quality and standard products to meet customer demand.Our cooperative production enterprises usually have abundant testing experience, high-end equipment and excellent personnel allocation.We in addition to the indicators of product testing method, testing standard and testing equipment for proofreading, also with the well-known third party testing institutions to cooperate authority and verification of the quality of product.

Cooperation with the third examination organization mainly include: Switzerland SGS (SGS), tienhsiang (Intertek), the spectrum test (PONY), will d international testing group (BV) China inspection certification group (CCIC), of course, we can also be selected according to the requirements of common recognition technology of the third party testing institutions.

We can also provide the following testing difficulty and equipment requirements of the customer.such as:

1.Qualitative and quantitative analysis of unknown impurity components {Spectra(UV、IR、NMR);Chromatography(gas phase,liquid phase,ion).Mass spectrometry (mass spectrometer, temperament usd together, liquid usd together);Energy spectrum (fluorescence spectra, diffraction spectra);Thermal spectrum (thermogravimetric analyzer, differential scanning calorimeter),In order to fully understand the sample, carries on the comprehensive analysis, through a variety of separation and analysis method, the treatment of the various components of the sample qualitative and quantitative analysis, so as to determine the structure of components}.

2.Analysis of trace metals in high purity compounds (ICP-MS;ICP-OES (applicable range: detection of products with purity of 99.999%)For more than 99.9999% of products, provide GDMS external inspection indicators and send EAG external inspection.

3.ROSH test (mercury, hexavalent chromium, cadmium, lead, polybrominated diphenyl ether)

4.Phase structure analysis (XRD) and powder particle size (laser particle size analyzer)

5.To help customers diagnose the problems caused by the product application experiment and analyze the reasons.

6.Analyze the ingredients of the new product, restore the sample formulation, and facilitate the imitation of production.

7.Compare and analyze the original sample and improve the difference of sample, so as to facilitate research and development or product improvement.

8.Product quality stability, safety testing.
