Disposable Permeation Tubes

KIN-TEK Trace Source™ disposable permeation tubes [brochure] are:

Polymer membranes about the size of a pencil containing the liquid phase of the component compound
Popular because they are small and convenient to use.

Standard Rate (SRT)	High Rate (HRT)	Extra Life (EL)

I. Standard Rate Disposable Permeation Tubes
	SRT Standard Rate Disposable Permeation Tubes
	SRT standard rate disposable permeation tubes generate moderate concentrations of high vapor pressure compounds. These compounds include SO₂, H₂S, NH₃, Cl₂, etc. Additionally, SRT permeation tubes can generate very low concentrations of low vapor pressure compounds such as carbon disulfide, methylene chloride and nitric acid. Typical emission rates yield concentrations of 1 to 10 ppm depending on the compound, operating temperature and dilution flow rate.
	SRT-2 Standard Rate Disposable Permeation Tubes
	SRT-2 disposable permeation tubes can generate moderate concentrations of high vapor pressure compounds such as Cl₂, NO₂ and NH₃. These tubes can be used at temperatures up to 50°C. Typical emission rates yield concentrations of sub-ppm to 5 ppm depending on the compound, operating temperature and dilution flow rate.

II. HRT High Rate Disposable Permeation Tubes

HRT permeation tubes can generate moderate concentrations of low vapor pressure compounds. These compounds include C₂H₅SH, CCl₄, acrylonitrile, benzene, styrene and water. HRT tubes are also used for generating high concentrations of SO₂, CH₃SH and other moderate vapor pressure compounds. Typical emission rates yield concentrations of 1 to 20 ppm, depending on the compound, operating temperature and dilution flow rate.

III. Extra Life Disposable Permeation Tubes

Extra life (EL) permeation tubes are designed to have a longer operating life than other disposable tubes and are recommended for special compounds.

	ELHRT Extra Life High Rate Disposable Permeation Tubes
	ELHRT permeation tubes are used for generating moderate concentrations of low vapor pressure compounds such as C₂H₅SH, benzene, and water, and for generating high concentration mixtues of SO₂, CH₃SH and other moderate vapor pressure compounds. Typical emission rates yield concentrations of 1 to 10 ppm, depending on the compound, operating temperature and dilution flow rate.
	ELSRT Extra Life Standard Rate Disposable Permeation Tubes
	ELSRT permeation tubes are used for generating moderate concentrations of high vapor pressure compounds such as SO₂, H₂S, NH₃, and Cl₂, and for generating very low concentrations of low vapor pressure compounds such as benzene, acrolein, and water. Typical emission rates yield concentrations of 1 to 5 ppm, depending on the compound, operating temperature and dilution flow rate.
	ELSRT-2 Extra Life Standard Rate Disposable Permeation Tubes
	ELSRT-2 permeation tubes are used for generating low to moderate concentrations of high vapor pressure compounds such as Cl₂, NO₂ and NH₃. Typical emission rates yield concentrations of sub-ppm to 2.5 ppm, depending on the compound, operating temperature and dilution flow rate. This type of tube is also used for field service where higher operating temperatures may be required.

Refillable Permeation Tubes

KIN-TEK Trace Source™ refillable permeation tubes [Brochure]:

Have a broader concentration range than the Trace Source™ disposable permeation tubes.
Are recommended for long-term use and special applications requiring a wide range of calibration points.
Are available for chemicals that are not typically suitable for disposable permeation tubes such as CO, CO₂, NO, methane, ethane, arsine & phosphine.
Emission rate of the tube membrane is certified by the Factory
Most tubes are periodically returned to KIN-TEK for refill and recertification.

LFH Liquid-filled	57S and 57H Gas-filled	57 Series Prefilled

I. LFH Liquid-Filled Permeation Tubes
	Generate moderate to high concentration mixtures of low vapor pressure liquids such as acrylonitrile, benzene, methanol and water.
	Are usually filled by KIN-TEK before shipment but may be filled by the customer (with appropriate safety measures in place) for certain components (contact the Factory)
	Tube dimensions: 1¾ inch diameter by 6 inch height plus approx. 2 inch height of protruding tubing

II. 57S Gas-Filled Permeation Tubes
	Generate low concentration gas standards of high vapor pressure gases such as CO, CO₂, NO, N₂O, CH₄ etc.
	Typical concentrations: sub-ppb to 10 ppm depending on tube emission rate and dilution flow rate
	Are usually filled by KIN-TEK but may optionally be filled by the customer (with appropriate safety measures in place) for certain components (contact the Factory). Customer-refill may require a gas feed "GF" module of the 491M or FlexStream gas standards generator.
	Tube dimensions: 1¾ inch diameter by 6 inch height plus approx. 2 inch height of protruding tubing

III. 57H Gas-Filled Permeation Tubes
	Generate high concentration mixtures of high vapor pressure gases CO, CO₂, and NO
	Typical concentrations: 10 ppm to over 1,000 ppm depending on tube emission rate, dilution flow rate and operating pressure
	Are filled by the customer using the controls of a gas feed "GF" module of a KIN-TEK 491M or FlexStream gas standards generator.
	Tube dimensions: 1¾ inch diameter by 6 inch height plus approx. 2 inch height of protruding tubing

IV. Prefilled Permeation Tubes Series 57 Prefilled permeation tubes are used in KIN-TEK gas standards generators to create gas standards ranging from less than 50 ppb to 5 ppm (depending on tube emission rate and dilution flow rate) for arsine and other hydride gases, as well as highly reactive gases such as HCl, HBr, O₂ and CO. The high vapor pressure of these compounds makes them unsuitable for use in disposable permeation tubes. [Brochure] Description:
	Factory-prefilled permeation tubes
	Factory-certified emission rate
	Small amount of toxic material (typically less than 4 grams of pure gas under 50 psig)
	Capable of safely using the gas phase of high vapor pressure compounds
	Tube dimensions: 1¾ inch diameter by 6 inch height plus approx. 5.5 inch height of pressure gage and protruding tubing (may require removal of cover in some KIN-TEK instruments)

V. Refill and Recertification
	Return (with RMA number) to KIN-TEK Technical Services for refill and recertification.
