Analysis Of Factors Affecting The Stability Of Chromogenic Substrate ADOS Reagent

Storage conditions

1.1 Storage Temperature and Humidity

The stability of ADOS is affected by storage conditions. Research has shown that ADOS should be stored in a low-temperature, dry environment to avoid changes in its chemical structure. The recommended storage temperature is usually below room temperature, with humidity controlled at a lower level to prevent the absorption of water molecules and the acceleration of chemical reactions. High temperature and humidity can cause chemical bond breakage within ADOS molecules, thereby reducing their color rendering effect and stability.

1.2 Lighting conditions

Light is also an important factor affecting the stability of ADOS. Long term exposure to strong light, especially ultraviolet radiation, can accelerate the degradation process of ADOS, causing it to lose its original color rendering ability. Therefore, during storage and transportation, direct sunlight should be avoided as much as possible, and light shielded packaging and containers should be used.

Chemical environmental factors

2.1 pH value

The color reaction of ADOS is effective within a specific pH range, but beyond this range, the stability of ADOS may be affected, which may lead to poor color development. Therefore, when using ADOS for biochemical testing, it is necessary to control the pH value of the solution to ensure its stability and accuracy.

2.2 Oxidizing and Reducing Agents

The presence of oxidants and reducing agents directly affects the chemical stability of ADOS. Strong oxidants such as hydrogen peroxide and potassium permanganate may trigger the oxidation reaction of ADOS, leading to its structural damage; Reducing agents may cause ADOS to lose electrons and reduce its color rendering ability. Therefore, direct contact with these substances should be avoided during the operation process.

Physical factors

3.1 Mechanical stress

ADOS, as a solid powder or crystal, may undergo physical changes such as pulverization and agglomeration when subjected to mechanical stress, thereby affecting its solubility and stability. Therefore, during the retrieval and storage process, it is advisable to avoid severe vibrations and friction as much as possible, and maintain its original physical form.

3.2 Dust exposure

The dust exposure of ADOS is also a concern that needs attention. Long term exposure to dust in the air can easily absorb moisture and impurities, leading to a decrease in the purity and stability of ADOS. Therefore, dust prevention measures should be taken during use and storage, such as wearing dust masks and using sealed containers.
