Aluminium-foil composite film is composite made of nylon membrane(PA),aluminum foil(AL)and polyethylene film(PE)with two-component adhesive.
Multi-Layer Foil
Ideal for sampling and storing H2S, and for low molecular weight
compounds such as Methane, CO/CO2, Hydrogen, and inert gases which
are not stable in Tedlar, ALTEF, or FEP. Water- and vapour-proof,
these flexible bags protect light sensitive compounds. Bags are
available with several fitting and valve options. They provide up
to five day sample stability with minimal absorption.
Features:
•excellent physical strength and chemical inertness
•no transparent,low adsorption and low permeability and
air-tightness
•convenient to collect and store gas samples
•the bag is of plastic valve or metal valve,filling gas
displacement is convenient; unique high-elastic tensile rubber
sample pad is dedicated to needle sampling
•widely used in petrochemical industry, environmental protection
and scientific research institutes
•Standard Aluminium foil multi-layer Gas Sampling Bag
Sizes:0.5L,1L,2L,3L,4L,5L,8L,10L,15L,20L,30L, 40L~6000L or
customized size.
Select from a variety of sizes to suit your needs.

Applicable scope:
Aluminium-foil composite multi-layer film gas sampling bags can be
used for light sensitive gas samples preservation,Mainly used for
conventional analysis of sampling,filling stable chemical
properties gas,e.g.oil cracking gas,natural gas,coal bed gas,smoke
gas,ambient atmosphere,technological process reaction gas and
inorganic gas such as nitrogen hydrogen oxygen argon gas.

Operating guide & Precautions:
• Avoid filling pressure higher than 6000Pa. Fill gas until the bag is fully expanded, however, it is not so tense when you press it using your finger.The overpressure filling can cause gas sampling bag burst damage.
• Operating temperature: -15℃~+60℃.
• Keep away from flame and high temperature when filling and
storage. Avoid contacting sharp stuff.
• Before use, flush sampling bags three times with the gas you want
to fill.
• The connection of valve and instrument or the equipment best be
adopted correspongding latex tube or silicone tube transition.
• For sulphide and halogen gas ,high content such as the percentage
level or low content such as PPM level are not recommended to use
• As the composite membrane using two-component adhesive when
composition,it can volatilize benzene, ketones, ethers, esters and
other organic matter,So we should pay attention to the
Aluminium-plastic composite membrane separating out the residual
organic matter can pollute the sampling gas inside the bag,analysis
data can cause interference.
• The gas sampling bag should be cleaned repeatedly replacement if
it is reused. Suggest the same sample bag collecting samples of the
same kind gas, don't mix
• The sample gas in sampling bag to save time should not be too
long,specific saving time depend on detection limit of experimental
analysis requirement,gas component species,temperature and
humidity,pressure,etc:generally,for pure inert gas,sampling bag can
be used as a temporary storage container and recommended storage
time less than 72 hours;for standard gas,flue gas,ambient
atmosphere,recommended storage time less than 24 hours.
• High purity nitrogen gas heating replacement can reduce the
interference of organic deposition
• When sampling and cleaning,please do not exceed 80% of the
calibration volume,take 1L sampling bag for example,suggest
sampling volume is less than 0.8 L.
• There must be a blank sample compare for precise experimental
analysis to do background deduction.
• For high-temperature high-pressure gas should be down to normal
temperature and pressure to sample,specific treatment method
according to actual situation.
• For negative pressure gas, should be sampled by appropriate power
and flow rate vacuum pump.
• For the gas containing particulate matter,dust and
aerosols,should adopt filter to prevent polluting the sample
bag,then difficult to clean.
