The analysis of various gas mixtures such as volatile organic compounds (VOCs) in air, breath analysis constituents, and indoor air pollutants requires calibration with accurate and reliable gas standards that mimic actual conditions. Humidity in various environments creates more challenges for accurate quantitative analysis and must be added to the calibration method.
KIN-TEK Analytical, Inc. provides products to create complex gas mixtures ranging from 2 or more different compounds in a single span gas stream. Each KIN-TEK permeation oven can hold up to 8 Trace Source™ disposable permeation tubes or 1 refillable permeation tube (depending on the application). Multiple oven permeation modules can be linked to increase the number of calibration gases desired.
KIN-TEK offers a Humidified Gas Module (HG Module) for creating %RH from ~20% to 90% RH (depending on the application) and can fulfill the need to calibrate in the same environment of real sampling.
