How it Works: Permeation Tube Technology

HOW PERMEATION TUBES WORK!

KIN-TEK Trace Source™permeation tubes use a permeable membrane to dispense a small flow of chemical vapor. The most common type is a small tubular device that has liquid analyte sealed inside the tube. A very small but stable flow (nanograms-per-minute) of analyte vapor is emitted through the tube wall at constant temperature. The emission rate of the tube is determined by measuring the rate of weight loss. These tubes are used in KIN-TEK Gas Standard Generators to create dynamic calibration gas standards with concentrations traceable to NIST through physical standards. Immersing the tube in a carefully controlled flow of inert dilution gas forms a trace concentration mixture of the analyte.

Trace Source™ permeation tubes: Accurate, Safe, and Easy-to-use
While both Trace Source™ Permeation Tubes and gas cylinders are certified NIST traceable calibration gas standards, Trace Source™ Permeation Tubes provide:

Ease of storage and handling of multiple compounds.
Pure standard without addition of impurities or loss due to absorption.
Multiple gases and a multipoint calibration curve generated easily using a Trace Source™ Permeation Tube in a KIN-TEK Gas Standard Generator.
Over 550 NIST-traceable chemical compounds available, including toxic air pollutants, VOCs, acid gases, amines, sulfurs and hydrides.

Gulf Coast Conference 2021

Join us at Gulf Coast Conference to learn out KIN-TEK’s dependable on-line gas calibration for your Process Analyzers including your Process GC’s.

The Span Pac I Gas Standard Generator system dynamically creates trace gas standards for on-line calibration of process analyzers for over 550 chemicals, capable of generating NIST traceable gas standard concentrations from sub-ppb to over 1,000 ppm. The system has an output signal for switching the analyzer input from sample to calibration gas, or it can be integrated with existing sample systems.

KIN-TEK Analytical Inc. Span Pac I Units are designed for N.E.C. Class 1, Group C or D, Div II hazardous atmospheres and can be adapted to Div 1 service in order to work side-by-side with your process analyzers.

We look forward to seeing you at GCC 2021.

Calibration Flexibility

KIN-TEK Analytical, Inc. provides the FlexStream™ series of modular gas standard generators that allow the user to pick and choose the modules needed to create the best calibration scenario.

Start with a FlexStream™ Base Module and add other modules, as needed. Offering over 550 chemical gas standards, we provide flexibility to create gas standards in the ppm, ppb, pptr concentration ranges that can be mixed, used individually, or supplied in a humidified gas matrix (non-reactive) to calibrate analyzers, detectors, or sensors in real-time scenarios. Standards are created dynamically so you have a fresh standard with each use that is accurate, repeatable, and reliable.

The FlexStream™ Product line provides flexibility by combining different modules (up to 6 in a series), and flexibility with easy-to-use included FlexLink™ Software. Create your own specialty gas mixture with confidence.

Reach out to us with your needs and we will quickly propose a solution for your Gas Calibration needs.
