What is NTA and what is NTA?

NTA is a complexing agent, and the specific information has been clearly stated on the first floor.

NTA is a secure plug-and-play appliance that combines IBM XSeries technology, BladeCenter, VPN, web, and thin client technologies with the following key features:

Securely running data center applications in the WAN, NTA integrates security modules in the Internet, including firewalls, SSL VPNs, digital certificates, various types of password authentication, etc., to provide a secure and complete solution for remote access on the WAN.

Securely implement cross-platform access using a standard browser.

As an application layer gateway, NTA can support any operating platform in the enterprise, including: Mainfram E, IBM AIX, HP UNIX, Sun Solaris, SCO UNIX, Linux, Win2000, etc., seamlessly integrate the application system of the enterprise, so that the enterprise information structure is integrated, at the same time, as the gateway of the application layer of the bastion host, NTA hides the IP address of the key server in the data center to prevent the host of the center from being attacked.

3.Lowest bandwidth usage.

With the NTA platform, only the mouse, keyboard, and compressed running results are transmitted on the network, and the use of bandwidth is minimized, extending applications from the LAN directly to the WAN.

4.Convert the CS application pattern directly to the BS structure.

The application system of the traditional CS structure runs stably in performance, but it is not the development trend of the future, and the application software development cycle of the BS structure is long, the cost is large, the difficulty is high, and the system resources are occupied, and the NTA platform is used, the application system of the CS or host terminal mode can be directly converted into the BS structure, so that all the application systems in the enterprise group can use the standard browser to run, and the application of the BS structure in the enterprise can be optimized at the same time.

Nitrilotriacetic acid is a very good fixing agent, which plays a role as a stabilizer in the production of styrene, and a catalyst and complexing agent in the production of polyurethane foam.

The nickel chloride or nickel sulfate in the NI column can bind to basic protein proteins with a HIS (histone) tag, which is typically 6 histidines (basic amino acids). After the protein is loaded, the histidine-tagged protein binds specifically to the column and the other miscellaneous proteins flow out. Ni-NTA purification medium is Ni-ion metal chelating medium.

1. Chelation has a wide range of applications in chemical research and industrial production.

2. In the chemical industry and industrial production process, adding chelating agent to make metal ions generate chelates with completely different properties is the main method to reduce and control the concentration of metal ions.

3. Chelate is widely used in mineral flotation process, hydrometallurgy, extraction and separation of metal elements, catalytic synthesis of substances, softening of water, electroplating process, pharmaceutical industry, dyeing process, etc.

4. Chelate is widely used in the bleaching of chemical, mechanical and deinking pulp of hydrogen peroxide and hypochlorous acid as bleaching agent. Some chelating agents can be used in medicine for lead and mercury poisoning. The specific uses are as follows:

1) It can effectively inhibit the catalytic decomposition caused by metal ions to hydrogen peroxide and hypochlorous acid bleach, improve bleaching efficiency, save bleaching liquid, and reduce bleaching costs.

2) It has a strong capture ability and dispersion effect on Fe3+ ions, avoids the reaction of Fe3+ ions with phenolic groups in the pulp to form a dark complex, protects the fiber, improves the whiteness of the pulp, and reduces the yellowing of the pulp.

3) It can effectively prevent the chemical reaction of metal ions such as calcium and magnesium in the pulp bleaching process to form precipitate, so as to prevent the scaling of system equipment and pipelines, and gradually remove the original scaling of the rinsing system.

4) It has a certain dispersion ability, which can improve the dispersibility of sodium silicate.

5) Protect the pulp fiber and prevent the damage to the fiber by the NaOH peeling reaction.

6) Compared with the traditional DTPA, it has a good cost performance.

7) It is used for the separation and purification of metal elements, the dyeing of fabrics and the manufacture of organic pigments.

In the washing industry, it is used to improve water quality and soften water quality, and you use tap water and well water to feel that the quality of the products produced is not good, so you can use chelating agent and 1% to improve the calcium, iron and magnesium ions in the water. And so much like that, do a pH test with tap water, and if the pH is a little bit of chelating agent, the pH is 5-6.

Chelating agents are also known as metal ion stabilizers.

In the circulating water treatment industry, it can also be called antiscalant and water quality stabilizer; In the industrial cleaning industry, chelating agents can play a role in stabilizing heavy metal softened water and achieving the current level of cleaning aids. In the textile printing and dyeing industry, as in the industrial cleaning industry, it stabilizes metal ions, improves the fineness of dyed products, and so on. Of course, there are many varieties of chelating agents, including organic, inorganic, phosphorus-containing and non-phosphorus-free.

What is the composition of the buffer.

The main components are: NaCl, Tris-HCl (pH=8), EDTA (pH=8), and Tris-HCl mainly regulates the pH of the solution and maintains a certain ion concentration. EDTA is mainly a chelating agent of divalent metal ions, which binds the calcium and magnesium ions in the DNA enzymes that affect DNA to EDTA, making the enzyme inactive, which is conducive to the extraction of complete DNA; SDS is mainly combined with proteins to deform and precipitate, which is conducive to DNA extraction, reducing and removing white matter impurities!

Let's take a look at the principle of the combination of nickel column and protein: histidine is an amino acid with heterocyclic rings, and each group of amino acids contains it can be seen in the instructions of Shanghai Biotech's **Shang**ni-NTA kit, product number BSP033-2

Aminotriacetic acid (NTA) uses.

NTA is a very important ammonia carboxyl complexing agent, which can be widely used in the field of fine chemicals, and in foreign countries, it is widely used in various industrial fields, especially detergents, scale inhibitors and descalers, cyanide-free plating, polyurethane foam foaming catalysts, etc. Specific uses are listed below: 1 Detergents 2 Electroless and electroplating 3 Descalers and antiscalants 4 Plastic additives 5 Printing and dyeing 6 Desulfurization 7 Chemical analysis 8 Photography 9 Chelating agents 10 Acidizing agents 11 Others In addition to the above uses, NTA has many other uses:

NTA is used as a foaming catalyst for polyurethane pin foam, which is a new use of non-tass used in foreign countries in recent years, which can immediately foam and quickly gel, and the amount of use is large, which is very promising for development. NTA can be used for the washing of rare earth elements. NTA can be used as a growth inhibitor for rice, barley, tomato and other crops, and can regulate the growth of crops and regulate their harvest period.

NTA's higher alipotic ammonia inhibits the growth of bacteria and fungi. The deodorant prepared with NTA has a deodorization rate of NH3, and the deodorization rate of MESH, ME3N, H2S, indole and 3-methylindole are0%。

The viscosity of printing inks and other industrially produced slurries can be adjusted by adding NTA. As a stabilizer, NTA can be added to metal anticorrosive coatings, paper waterproof coatings, pesticides, daily chemicals, diacetone alcohols and other chemicals, which can improve the stability of products.
