Difficulties with obtaining suitable reference materials, which are applied for validation of analytical procedures and calibration of measured devices used in gaseous examinations (atmospheric air, indoor air, workplace atmosphere), are one of the most important challenges that stand in front of analytics. Known gaseous standard mixtures preparation techniques, both static and dynamic, are burdened with lots of inconveniences and disadvantages, which can be responsible for false analytical results. It appears that a very important step in the way of obtaining suitable reference materials useful in gaseous analysis is the technique of thermal decomposition of surface compounds. The paper describes a new type of matrix-free reference material-chemically modified glass fiber, which significantly makes it easier and simplifies the usage of reference materials produced using this technique.
