What purity is medical grade nitrogen?

between 97-99.99%
Pharmaceutical-Grade Nitrogen Many drugs require high-grade nitrogen with a purity between 97-99.99%. This high to ultra-high purity nitrogen is used for nitrogen blanketing storage tanks, receptacles, and other equipment used in drug manufacturing.

What is high purity nitrogen?

High-purity grades of nitrogen are composed of greater than 99.998 percent nitrogen. The common high-purity grade names include Research Purity and Ultra High Purity. All of the high-purity grades can also be considered Zero grade.

What is medical grade nitrogen?

Nitrogen is used as a component of gas mixtures for medical use and as filling tool for sterile equipment. Furthermore it is used to create the upper part of pharmaceutical vials and as a propellant in aerosol pressurized containers.

How do I choose a nitrogen generator?

The choice of generator depends largely on the purity of nitrogen needed for the application being considered. For example, applications such as fire prevention require nitrogen of 95-98 percent purity and are a good fit for membrane generators.

How is nitrogen purity measured?

When producing nitrogen through on-site generation, purity is analyzed directly at the point of generation, moments before it enters the distribution network of pipe within the facility. Purity is analyzed using an internal oxygen sensor which displays the gas concentration in real time.

How is nitrogen purity calculated?

We’ve worked out that the mass of the pure substance nitrogen is 950 grams. And the mass of the sample in grams is 1200. Therefore, the percentage purity of nitrogen in the original mixture is 950 divided by 1200 multiplied by 100 percent. This is equal to 79.1667 percent.

What is pure nitrogen?

Pure nitrogen gas is an excellent carrier gas in analytical applications such as gas chromatography. Further examples are the use as a zero gas or purge gas.

What are nitrogen generators used for?

Nitrogen generators are used in hypoxic air fire prevention systems to produce air with a low oxygen content which will suppress a fire.

What does NF stand for in nitrogen?

National Formulary
Medical NF (National Formulary) Grade Nitrogen, Size 200 High Pressure Steel Cylinder, CGA-580.

What is pure nitrogen used for?

It is used to concentrate and reduce the volume of liquid samples. Nitrogen is also important to the chemical industry. It is used in production of fertilisers, nitric acid, nylon, dyes and explosives.

How reliable are nitrogen generators?

These nitrogen gas generators are capable of purities of up to 99.999% at flow are required for your scientific equipment. Peak Scientific’s Nitrogen generators are used in laboratories all over the world to supply various analytical instruments with the most reliable nitrogen gas source.

Within the nitrogen industry, the term “high purity” is generally considered to be any nitrogen that is composed of more than 99.9% nitrogen. High purity nitrogen is often called by different grade names depending on the manufacturer.

What are the UHP nitrogen specifications?

UHP nitrogen specifications are strict with variations rendering the classification invalid. The oxygen content of UHP gas can be no greater than 2 parts per million by volume (ppmv), total hydrocarbons cannot exceed 0.5 parts per million by volume, and moisture no greater than 1 part per million by volume).

How is nitrogen purity analyzed during on-site generation?

When producing nitrogen through on-site generation, purity is analyzed directly at the point of generation, moments before it enters the distribution network of pipe within the facility. Purity is analyzed using an internal oxygen sensor which displays the gas concentration in real time.

What is considered low purity nitrogen gas?

Nitrogen gas ranging between 90 to just under 99.9% is considered to be low-purity. Common low purity nitrogen gas brands include: Nitrogen gas manufacturers name their products differently with no standardized naming conventions.
