WET CHEMISTRY

INSTRUMENTAL WET CHEMISTRY,CLASSICAL WET CHEMISTRY

Wet chemical analysis, which is also known as wet chemistry, involves chemical techniques that are carried out on samples in a liquid phase. This type of analysis can often be conducted on very small samples that may not be suitable for other instrumental methods.

At Zhejiang Guojian Testing Technology Co., Ltd (CCT) , we offer both classical and instrumental wet chemistry services for analyzing the elemental composition of metal and alloy samples. Our laboratories are fully equipped with the necessary expertise and equipment to provide both qualitative and quantitative data.

WET CHEMISTRY SERVICES AT Zhejiang Guojian Testing Technology Co., Ltd (CCT)

At Zhejiang Guojian Testing Technology Co., Ltd (CCT) , we offer both classical and instrumental wet chemistry services for element analysis of metal and alloy samples. In our classical wet chemistry lab, we use traditional techniques such as Colorimetry, Gravimetry, and Titrimetry to identify a single element in a sample by manipulating it with laboratory beakers and flasks. On the other hand, our instrument laboratory provides wet analyses using automated and computerized methods such as ICP Chemistry, which includes ICP Atomic Emission Spectroscopy and ICP Mass Spectrometry Analysis, to analyze a full spectrum of elements in a sample. These methods provide streamlined analysis and data storage.

Zhejiang Guojian Testing Technology Co., Ltd (CCT) can test for the following chemical elements and more:

THE TEST PROCESSES

INSTRUMENTAL WET CHEMISTRY
ICP Chemistry

Zhejiang Guojian Testing Technology Co., Ltd (CCT) offers ICP chemistry using two methods: ICP-AES (Atomic Emission Spectroscopy) and ICP-MS (Mass Spectrometry Analysis). In this technique, the sample is mixed with argon gas, which is heated and charged with radio frequencies in the torch chamber of the ICP spectrometer, producing an argon plasma. This plasma removes any remaining solvent and causes sample atomization and ionization. The resulting spectrum provides information on the elements present in the sample.
ICP chemistry at Zhejiang Guojian Testing Technology Co., Ltd (CCT) is fully computerized and monitored to ensure accurate processing and reporting of wet chemical analysis results. The ICP-AES spectrometers can analyze 70 elements in the periodic table with high sensitivity and resolution. ICP-MS analysis can evaluate most elements in the periodic table and provide both qualitative and quantitative information on the elements present in the sample, including trace elements.

CLASSICAL WET CHEMISTRY

Classical wet chemistry methods comprise colorimetry, gravimetry, and titrimetry, which are commonly used for qualitative and quantitative analyses. Colorimetry is a qualitative method that relies on color changes to identify substances and measure their concentration. It uses the absorbance or transmittance of light to measure the concentration of a solute, which is proportional to the amount of substance in the solution. The absorbance measurement can be compared to a standard with a known concentration to determine the concentration of an unknown sample.

Gravimetry, on the other hand, is a quantitative method that measures the mass of a solid precipitate from a sample after dissolution. A known amount of the sample is weighed, dissolved, and treated to form a compound, and the collected solids are weighed. The amount of the constituent in the original sample is calculated from the mass of the precipitate and its chemical composition.

Titrimetry, also known as volumetric analysis, is another quantitative method that measures the volume of a liquid reagent required to react completely with a known amount of reactant. The reagent, known as the titrant, has a known concentration and volume. When the endpoint of the reaction is reached, the exact amount of reactant that has been consumed can be determined. Visual indicators such as color changes can be used to detect the endpoint of a reaction.
