Dry chemistry vs wet chemistry

Wet chemistry is a method of preparing materials by chemical reactions in which a liquid phase is involved. Example: Triglyceride assay (wet chemical method).

Triglycerides are extracted from serum and proteins are precipitated, and glycerol is released using potassium hydroxide. The glycerol is then oxidized with sodium periodate to formaldehyde. Finally, the fluorochrome is produced by a chromogenic acid reaction or by acetylacetone color development (determined by fluorometric or colorimetric methods).

Dry chemistry refers to the method of chemical reactions used to carry out the test requires very little water. For example, urine testing is now done with dry test strips and instruments. In the past, reagents were used to react with urine in a test tube. This method is called "dry chemistry".

Dry chemistry analyzer vs. wet chemistry analyzer

A. Different types of reagents

a. Fully automated chemistry analyzer (wet type): An instrument that measures a specific chemical composition in body fluids based on the photoelectric colorimetric principle. The reagent used is liquid.
b. Fully automatic dry chemistry analyzer: The reagents used are dry tablet reagents.

B. Different scope of use

a. Fully automatic chemistry analyzer (wet type): fast measurement speed, high accuracy, small amount of consumed reagents. Has been widely used in hospitals, epidemic prevention stations and other places at all levels
b. Automatic dry chemistry analyzer: the scope of application for clinical blood, urine specimens of biochemical project testing.

Veterinary biochemical testing is the testing of multiple chemical components within a sample. The levels of these chemicals reflect many conditions in various organs of the body. Most veterinary biochemical tests measure blood electrolytes and assist in the diagnosis of liver, kidney and pancreatic disease.

Dry Chemistry Testing Principle - Accurate, Simple and Fast

Dry chemistry analytical techniques are relative to wet chemistry techniques. Dry chemistry is the direct addition of a liquid test sample to a dry reagent produced specifically for a different project. The moisture of the sample under test is used as a solvent to cause a specific chemical reaction, which leads to a chemical analysis method. Dry chemistry is a class of analytical methods based on enzymatic methods. Dry chemistry can also be called solid phase chemistry. Dry chemistry uses reflectance photometry or differential electrode method as a measurement method.
