Dry Chemical Testing
Dry chemistry analysis is the term that corresponds to wet chemistry techniques. A dry chemistry analyzer is a process in which a liquid test sample is added directly to dry reagent strips manufactured specifically for each project. Dry chemistry analyzers utilize the water in the sample being tested as a solvent to initiate a specific chemical reaction that results in a chemical analysis.

This type of analysis is a class of analytical methods based on enzymatic methods. Dry chemistry is also known as dry reagent chemistry or solid phase chemistry.

Advantages of Dry Chemistry
Dry chemistry analyzers use either reflectance photometry or differential electrode methods as a means of measurement.

It has the following key features:

1.
High accuracy and speed (Seamaty SD1 fully automated dry chemistry analyzer produces results in less than 12 minutes).
2.
Easy to operate, no daily calibration required.
3.
No need to store other reagents or prepare any solutions.
4.
No sample pre-treatment is required. The multilayer membrane has a selective filtration function, which reduces the influence of interfering substances during the assay.
5.
The sample volume is small (only 100 µl for the SD1 automatic dry chemistry analyzer). Moisture during the reaction is supplied by the liquid component of the sample, increasing the sensitivity of the measurement.
6.
Based on the principle of differential electrode method, the multilayer membrane is disposable. Therefore, it has the advantages of the conventional electrode method while avoiding its disadvantages.
7.
It can replace wet chemistry for emergency samples in some cases. It can also be used for methodological evaluation of routine test results, etc.
Dry chemistry is not only used for qualitative tests but has also been developed as a semi-quantitative and quantitative analytical method. It has become an important methodological category in clinical testing.

Dry Chemistry Analyzer
Dry chemistry testing has made tremendous progress in qualitative urine testing. Some test strips can now measure multiple items simultaneously. For example, urinary protein, urinary glucose, occult blood, bilirubin, urobilinogen, ketone bodies, specific gravity, nitrites, and bacteriuria.

Disadvantages of dry chemistry
The high cost of reagents for dry chemistry analyzers places a greater financial burden on patients. In addition, dry chemistry reagents are difficult to store, have a short expiration date, and require high storage temperatures.
