Film Key Features

ALTEF is a proprietary fluoropolymer film developed specially for the air sampling market.
ALTEF meets or exceeds many of the desired characteristics of Tedlar®.
Unlike Tedlar®, ALTEF does not exhibit background levels of DMAC and phenol.
ALTEFexhibits similar stability properties as Tedlar® for a wide variety of compounds, including most VOCs.
Low VOC and sulfur background levels.
Contains no additives, fillers or pigments.
Minimal adsorption.
Superior storage for organics.
Abrasion Resistant.

Suggestion

Before use, thoroughly flush bags with ultra-pure nitrogen or zero air
During sampling, Fluoropolymer tubing and Fluoropolymer faced septums must be used in order to prevent sample loss.
Bags should not be filled to more than 80% of their maximum volume.
Charcoal (Black) Tedlar^® bags should be used when sampling light sensitive compounds
Do not store compounds in bags long term due to the possibility that chemicals may adsorb onto the bag surface.
Bags should not be used to collect reactive or unstable compounds.
When shipping bags, do not air-ship unless the bags are stored in a pressurized area.

Film Properties

Developed specifically for gas sampling applications
Chemically inert to most acids, aliphatic and aromatic organic compounds, chlorinated solvents, and alcohols
Maximum operating temp: 260 ºF
ALTEF bags are made of 0.003" thick film.
Tensile Strength 6100 psi

Film Advantages

Suitable for sampling most VOCs and many sulfur compounds
Low VOC background
Longer sample storage times than most other bag materials
Does not exhibit background levels of DMAC or phenol, as Tedlar^® does
Lower permeability than Tedlar^® to CO₂, N₂, CH₄
Superior resistance to solvents

Film Limitations

More permeable to most compounds than Tedlar^® (0.003" thick versus 0.002" for Tedlar^® Bags)
Not suitable for sampling ketones and esters in high concentrations (>30 %)
Less resistance to UV light than Tedlar^®
Many sulfur compounds should be analyzed within 24 hours.
More expensive than Tedlar^®

Valve/Fitting Benefits

Economical: Cost savings in manufacturing is passed on to customers. Septum can be changed.
Reduces shipping costs. Easier to carry in the field.
Ensures purity of sample and non-contamination.
Quick, easy opening and closing of valve: saves time. Cap stop leaks from opening cap too far.
Prevents accidental sample loss. No guessing whether valve is open or closed.
Allows reuse of valve by replacing inexpensive septum.
Designed specifically for gas sampling applications.

Economical: Cost savings in manufacturing is passed on to customers.
Reduces shipping costs. Easier to carry multiple bags into the field.
Ensures purity of sample and non contamination.
Quick, easy opening and closing of valve (< 1 second).
Faster than "twist action" valves.
Locked position is easy to verify visually, and prevents accidental sample loss during shipment. Virtually impossible to open or close valve to far.
Septum does not come into contact with sample inside bag. Septum allows repeated punctures with syringes without leakage. Ultra low bleed silicone prevents contamination.
Designed specifically for gas sampling applications.
