What are UHP gases?

What are UHP gases?

Ultra High Purity (UHP) Gases Air Products’ Experis® ultra-high purity (UHP) gases range includes acetylene, argon, carbon dioxide, hydrogen, helium, nitrogen, oxygen and synthetic air (zero air) all of which have been designed to deliver peace of mind whatever your application or use.

What is ultra high purity gas?

Ultra High Purity Gases are single gases; such as Oxygen, Hydrogen, Nitrogen, Argon, Helium, Oxygen, Carbon Dioxide and in other Speciality Gases, with a purity of equal or greater than 99.9995% meaning that 0.0005% of the gas is comprised of other gases (impurities).

What is nitrogen UHP?

What Is Ultra High Purity (UHP) Nitrogen Gas? Ultra-high purity nitrogen gas refers to a nitrogen gas concentration of 99.999% with negligible impurities. UHP nitrogen specifications are strict with variations rendering the classification invalid.

What is UHP hydrogen?

Air Products’ Experis speciality gases range includes a number of UHP (ultra-high purity) Hydrogen products with specifications intended to deliver peace of mind whatever your application.

What is UHP oxygen?

Oxygen Ultra Pure Air Products’ Experis® speciality gases range includes a number of UHP (ultra-high purity) oxygen products with specifications intended to deliver peace of mind whatever your application.

What is UHP helium?

Ultra high purity: 99.999% This grade of helium also has a wide range of uses across research and scientific uses where the highest purity gases aren’t necessary.

What is gas density?

Gas density is defined as the mass of the gas occupying a certain volume at specified pressure and temperature. The density is usually represented in units of lbm/ft3. Another common density representation is the “gas gradient” that is expressed in units of psi/ft.

How much nitrogen is in a 300 cylinder?

3600/6000 P.S.I.
300 (HH) 305 cu. ft. Argon 3600/6000 P.S.I. Nitrogen 3600/6000 P.S.I.

What is ultra high purity oxygen?

Ultra High purity oxygen is for specialized applications and demanding laboratory applications Oxygen is used in analytical instruments such as AAS. Furnace atmospheres require low moisture levels to maintain instrument sensitivity and impurities limits.

What is high purity helium?

Grade 5 (5.0 helium = 99.999% purity) This high purity grade helium is also widely used for gas chromatography, mass spectrometry, and specific laboratory research when higher purity gases are not necessary, as well as for weather balloons and blimps.

What percentage of helium is used in balloons?

Isn’t there a better alternative? Although party balloons and weather balloons account for only about 7 percent of helium use, it would be nice if there was another choice. However, if you want the balloon to go up, there really is no other choice. All other gases are flammable, explosive or too heavy.

What is the standard density of gas?

Density of Gases

How is gas purity calculated?

Purity Ratings Vs Specialty Gas Concentration To work out the total possible impurities, subtract the purity rating from 100%, and multiply this figure by the total number of units. Example 1: Nitrogen with a rating of 5.0, equals 99.999% purity. 100% – 99.999% = 0.001% total possible impurities.

What is the volume of nitrogen gas?

What is the volume of two moles of diatomic nitrogen gas at STP? Explanation: One mole of gas has a volume of 22.4L at STP.

What is ultra high purity nitrogen gas (UHP)?

What Is Ultra High Purity (UHP) Nitrogen Gas? Ultra-high purity nitrogen gas refers to a nitrogen gas concentration of 99.999% with negligible impurities. UHP nitrogen specifications are strict with variations rendering the classification invalid.

What is zero grade high purity nitrogen gas?

Zero grade high purity nitrogen gas is categorized as such because they contain less than 0.5 parts per million of hydrocarbon impurities. Nitrogen gas ranging between 90 to just under 99.9% is considered to be low-purity.

What are the different grade of nitrogen gas?

Pure grade nitrogen classifications include N2.0, N3.0, N4.0, N5.0, N6.0, and N7.0. What Is Ultra High Purity (UHP) Nitrogen Gas?

What is high-purity nitrogen used for?

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. High purity nitrogen is also used in drug packaging to help retain freshness and keep active ingredients from deteriorating.
