Tris, or tris(hydroxymethyl)aminomethane, has been widely used as a pH buffer in biological media for about 35 years. The near-ideal properties of this biological buffer are the reason for its popularity. Tris does not absorb water, is easily soluble in water, and has high purity. It does not precipitate calcium salts, is stable in solution for several months at room temperature, and does not seem to inhibit many enzyme systems. However, due to the chemical and physical properties of Tris buffer, improper use may lead to erroneous pH measurement of the electrode system.
The influence of pH in TRIS buffer on electrode
Biochemists use TRIS buffers to control the pH within the physiological range (approximately 7 to 8 pH), because phosphate can cause adverse reactions with biological substances in the test sample. However, when pH measurements are to be made on these solutions, another type of "adverse side reaction" must be recognized, involving the pH electrode system.
The influence of chemical and physical properties of Tris buffer on pH
Tris, which is commonly used for physiological measurement (pH 7 to 7.5), does not have a large buffer capacity. Therefore, caution should be exercised when using tris buffer to control sample pH. The rather large temperature coefficient of tris (-0.028pH/ C) is also worth considering. For example, if the meter is calibrated with tris buffer and the tris temperature is 20 C, using a pH value of 25 C will cause errors. Therefore, temperature pH dependence must be used when using tris for standardization. When using tris to control the pH of the sample, the degree of control will depend on the sample temperature. If the sample temperature changes by 2 C, the pH control changes by about 0.06 pH units. The required pH control will determine the maximum allowable temperature fluctuations.
Advantages of Tris buffer
Because the Tris base is highly alkaline, this buffer system can be used to prepare buffers with a wide range of pH values from acidic to alkaline;
It has little interference to the biochemical process, and does not precipitate with calcium, magnesium ions and heavy metal ions.
Disadvantages of Tris buffer
The pH value of the buffer is greatly affected by the concentration of the solution. The buffer is diluted ten times, and the pH change is greater than 0.1; the Tris buffer should be prepared from high-purity tris and HCl using distilled or deionized water without CO2.
The temperature effect is large, and the temperature change has a great influence on the pH value of the buffer, so it must be prepared at the use temperature, and the Tris-HCl buffer prepared at room temperature cannot be used at 0 C to 4 C;
It is easy to absorb CO2 in the air, so the prepared buffer should be tightly sealed;
This buffer has a certain interference effect on some pH electrodes, so use an electrode compatible with Tris solution.
(1) Regular power graphite electrode( RP grade Graphite Electrode) . Graphite electrode with current density less than 17a / cm2 is allowed to be used in common power electric furnaces for steelmaking, silicon smelting and yellow phosphorus smelting.
(2) Oxidation resistant coating graphite electrode. A graphite electrode coated with an anti-oxidation protective layer (graphite electrode anti oxidant). The formation of both conductive and high temperature oxidation resistant protective layer can reduce the electrode consumption (19% ~ 50%), prolong the service life of the electrode (22% ~ 60%), and reduce the electric energy consumption of the electrode. The popularization and application of this technology can bring such economic and social effects as follows: 1. The unit consumption of graphite electrode is less, and the production cost is reduced to a certain extent. For example, according to the consumption of 35 graphite electrodes per week and 165 refining heats of LF refining furnace in a steel-making plant without shutdown in the whole year, 373 (153 tons) electrodes can be saved every year by using graphite electrode oxidation resistance technology, and RMB 2585700 can be saved by RMB 16900 per ton of ultra-high power electrode per year. 2 The graphite electrode consumes less electricity, saves the unit electricity consumption of steelmaking, saves the production cost, saves energy! 3. Because the graphite electrode is replaced less times, the labor amount and risk coefficient of operators are reduced, and the production efficiency is improved. 4 Graphite electrode is a high consumption and high pollution product, which has a very important social significance in the days of promoting energy conservation, emission reduction and environmental protection. This technology is still in the stage of research and development in China, and some domestic manufacturers have begun to produce it. It is widely used in Japan and other developed countries. At present, there are also companies that import the anti-oxidation protective coating in China.

IoLine-TrisB IoLine Tris Compatible pH Electrodes Description
The IoLine Tris compatible pH electrodes use a patented three chamber system with an iodine reservoir in the iodine/iodide reference electrode. The standard hydrogen electrode has proven too difficult in practical use to gain more than a mere theoretical importance. The Ag/AgCl reference system, which is the most common reference system, can cause measuring instabilities originating from potential variations with changing temperature or reactions between silver ions and the measuring solution in the area of the diaphragm. IoLine pH electrodes, in contrast, have the advantage of a much lower temperature sensitivity and a metal ion free reference system.

The nitrogen in DAP is readily available for plants, while phosphorus is essential for root development, flowering, and fruiting.
Solubility: Diammonium phosphate is highly water-soluble, making it easy to apply as a liquid fertilizer or to dissolve in irrigation systems.
pH and Acidity: DAP tends to be slightly acidic, which can contribute to lowering the pH of the soil over time. It is essential to monitor soil pH when using fertilizers to prevent overly acidic conditions.
Application: DAP is commonly used as a dry granular fertilizer that can be broadcast on the soil surface.
It can also be dissolved in water and applied as a liquid fertilizer through irrigation systems, providing quick nutrient availability to plants.
Uses: Diammonium phosphate is suitable for a variety of crops, including grains, fruits, vegetables, and legumes.
It is often used during the early stages of plant growth to promote root development.
Storage: DAP should be stored in a cool, dry place to prevent moisture absorption and caking.
Safety Considerations:
When handling DAP, it's important to follow safety guidelines and use appropriate protective equipment to prevent skin or eye contact and inhalation.
Compatibility: Diammonium phosphate is compatible with many other fertilizers and can be used in combination with them to provide a broader spectrum of nutrients.
Environmental Impact: Like other fertilizers, the application of DAP should be done responsibly to minimize environmental impact, such as nutrient runoff into water bodies.
Monoammonium phosphate (MAP) is a widely used fertilizer that provides essential nutrients to plants, particularly nitrogen and phosphorus. Here are some key points about monoammonium phosphate:
