Permeation Tubes (perm tube; wafer devices; sources of microflows)

Avaliable permeation tubes of various types, including wafer type (wafer device)

Please request a quote for more details…

PURPOSE AND SCOPE

  Permeation Tubes (perm tube; wafer devices; sources of microflows) of gases and vapors  – working reference standards of the 1st category complete with thermodiffusion generators of gas mixtures are intended for transferring a unit of mass concentration of a component in gaseous environment to working reference standards of the 2nd category and working measuring instruments in accordance with GOST 8.578-2008 “GSI. State verification schedule for means of measuring the content of components in gaseous environment “

Design and operation principle

  Permeation Tube (PT) is a vessel with permeable walls filled with a pure substance (liquid, solid or liquefied gas). The productivity of perm tubes (the amount of substance diffused from the permeation tube per unit of time) depends on the nature of the substance that is filled in the  source of microflows, as well as on the geometric dimensions, temperature and material of the vessel walls. When blown with a diluent gas, the substance diffuses into the gas stream at a constant rate, forming a gas mixture with a predetermined value mass concentration.

Depending on the number of nominal temperature values ​​and the corresponding performance values, permeation tubes refer to single-valued or multivalued.

  PTs differ in substance, temperature of application and constructive performance. Structurally, the perm tube can be made in the form of a PTFE tube, ampoule or plate, a metal or glass tank with a PTFE nozzle (film), a metal reservoir with an internal gas-permeable tube.

Advantages

– Wide range of reproducible organic and inorganic materials;

– Possibility of obtaining reproducible microconcentrations materials at the level of the MPC of working area and air of populated areas;

– Universal design, allowing to use PMs in generators of various types;

– Small weight and dimensions.

Construction type of permeation tube (PM).

 

Design Version.

Depending on the material of the capsule there are following types of performance:
– Made of gas-permeable PTFE tube length of 20 to 120 mm (tube, sealed at both ends);

– Made of PTFE;

– Plate made of fluoroplastic (PTFE tube in a metal casing);

– Made of chemically resistant glass (glass or steel reservoir with gas-permeable outer resin tube length of 5 to 50 mm);

– Made of steel (metal reservoir with gas-permeable membrane);

– Made of steel (metal reservoir with gas-permeable resin tube).

 

PMs are stored and transported in sealed plastic or metal containers. Each is supplied with a passport, an application instruction and a certificate of verification.

Permeation Tubes of gases and vapors are unrecoverable, beyond repair, single function products.

Remarks:

  • Specific values ​​of productivity (gH, mcg / min) are shown in the passport of permeation tube;

  • Allowable permeation tubes with the intermediate temperature to multiples of “1”.

The limits of permissible relative error (δ 0 ) of permeation tubes

(limits permissible relative error performance values (gH, mcg / min), reproducible with PTs)

± 7% at GH <1.0 mcg / min

± 5% at GH ≥ 1,0 mcg / min

The permissible relative deviation from the target performance value when ordering

not more than ± 15%

The limits of permissible relative error of the temperature coefficient

± 10%

Weight

not more than 20 g

Filling substance of perm tube 1)

not less than 70% of full capacity

Contents of the main component in the material for filling the PM 2)

not less than 99.0%

MTBF 3) (at a confidence probability of P = 0.95)

at least 12 000 hrs for the performance of nitrogen dioxide, sulfur dioxide, hydrogen sulfide, ammonia, benzene, toluene, o-xylene, m-xylene, p-xylene, ethylbenzene, hexane, methyl mercaptan, ethyl mercaptan, acetone, phenol, ethyl acetate, acetic acid, decane, naphthalene, methanol;

The limiting state of permeation tube, defined by the presence of substances in PM in % of full capacity (visually) or on weight 3)

less than 10%

Remarks:

1) – per customer’s desire is allowed substance filling not less than 60% of full capacity. Permitted filling material is not less than 50% of the full capacity of not more than 0.5 g / min for the permeation tube performance;

2) – perm tube may be filled with a substance content of the basic component is not less than 97% if the determination of the basic component of PM, certified in accordance with the GOST 8.563 – 2009 and in the substance absence of volatile components;

3) – continuous operation time of permeation tube during which metrological characteristics of PM stay fixed, subject to the conditions of transportation, storage and operation, taking into account the limit state – presence of a substance in perm tube: 10% of full capacity (visually) or by weight).

Contents of delivery
