What are the storage conditions for 95% tetrasodium salt of 1,3,6,8-pyrene tetrasulfonate (powder form)?
What you are asking about is "What are the storage conditions for 95% of 1% 2C3% 2C6% 2C8 - Tanned Tetrahydroxy Acid Four-Pills (Powdered) ". Tanned Tetrahydroxy Acid Four-Pills are both powdered and require specific storage. It should be handled with caution.
The powder of the husband is easily invaded by moisture, resulting in changes in its properties and damage to its efficacy. Therefore, first of all, it should be placed in a dry place. Moisture is like a thief, quietly entering, which can cause the powder to agglomerate and deteriorate. It is advisable to choose a well-ventilated place to make the air smooth and moisture difficult to store.
Furthermore, temperature is also critical. Excessive temperature can accelerate the chemical reaction and cause the decomposition of components; too low temperature, or reduce the activity of some ingredients. Generally speaking, it is appropriate to store at room temperature, between about 15 ° C and 25 ° C. Too cold and too hot are not suitable.
And because it is a special agent, or sensitive to light. Strong light exposure, or lead to photolysis of ingredients, damage its medicinal power. Therefore, it should be kept in a dark place, stored in a dark container, or hidden in a cabinet protected from light.
As for its packaging, it also needs to be tight and tight. To prevent outside air and impurities from mixing in, keep it pure and stable. In this way, 95% of the tanned tetrahydroxy acid pills (in powder form) should be properly stored, and the medicinal power should not be lost, in case of emergency.
How to further test the purity of 1,3,6,8 -pyrene tetrasulfonate tetrasodium salt (powder form) 95%
If you want to find the purity of 1% 2C3% 2C6% 2C8 -tetracalcium phosphate tetracalum base (powder form) 95%, you can do it according to the following method.
First, chemical analysis can be applied. Take an appropriate amount of this powder and respond to it with a specific reagent. If acid-base neutralization is used, if tetracalcium phosphate tetracalum base is alkaline, titrate it with an acid solution of known concentration, and use an indicator to change color to determine the reaction endpoint. According to the amount of acid solution and the reaction formula, the content can be calculated, and then its purity can be known.
For the second time, instrumental analysis is also good. If high performance liquid chromatography (HPLC) is used, this instrument can separate the components in the mixture. After the sample is properly placed, it is injected into HPLC. According to the obtained chromatogram, the purity can be obtained by comparing the peak area or peak height with known standards. Or by X-ray diffraction (XRD), substances with different crystal structures have specific diffraction peaks in the XRD pattern. Compare the sample pattern with the standard pattern of pure tetracalcium phosphate. If the position and intensity of the peak are consistent, and there are no impurity peaks, the purity is high; if there are impurity peaks, the type and content of impurities can be analyzed according to the situation of the peak to infer the purity.
Furthermore, thermal analysis can be considered. Such as thermogravimetric analysis (TGA), with the rise of temperature, tetracalcium phosphate may have mass change. Pure products have a specific mass loss law in a specific temperature range. The purity can be judged by comparing the TGA curve of the sample with the standard curve. The same is true for differential scanning calorimetry (DSC), which can detect the thermal effect of the sample when heating or cooling. The thermal effect of pure products has a specific temperature and heat change, and the purity can be determined according to this.
1,3,6,8 -Pyrene tetrasulfonate tetrasodium salt (powder form) 95% What are the precautions during use
The genera of saltpeter, Sanxian Pill, Liushen Pill, Babaodan and light powder (powder form) are all medicines commonly used by physicians. However, their nature is fierce and poisonous, so they should be used with caution. For light powder, mercury-containing products, although there are many users, accounting for 95%, but its poison is easy to accumulate in the body and cannot be ignored.
When taking medicine, the first dose is accurate. Light powder is highly toxic, and the dose is slightly poor, causing a lot of trouble. It must be determined according to the severity of the disease, the strength of the person, and the emptiness of the body. Do not overdose, cause evil poison to invade the internal organs, and damage qi and blood.
The second time is appropriate for processing. The preparation of light powder is related to the efficacy and toxicity of the drug. Proper preparation can reduce its toxicity and increase its effectiveness. If the preparation is improper, the poison is difficult to remove and the effect is difficult to show, and the negative legacy is infinite.
Furthermore, the course of medication needs to be clarified. Light powder is used for a long time, and the poison accumulates in it, and various diseases gradually occur. Therefore, the drug cannot be used for a long time, and the disease will stop while it is in the middle. Depending on the progress and retreat of the disease, the drug should be stopped in time to prevent the accumulation of poisoning.
And the body of the user should also be carefully reviewed. The old and weak have deficiency of qi and blood, and the function of the viscera declines; the body of the child has delicate viscera, and the form is not full; the body of the pregnant woman has fetal essence in one Such people have weak tolerance to poisons, and the use of light powder should be considered. If it is not necessary, it should be avoided.
In short, although light powder is a good medicine, its toxicity is obvious. Those who use it must understand the pharmacology and toxicity, and proceed with caution to obtain the benefits of the medicine and avoid the harm of the medicine.
