Certified reference materials are an essential component for any lab application in spectroscopy for a wide range of reasons. These qualify the system or instrument under study, confirming that it is suitable for its intended purpose. Thus, it acts as a benchmark for readings, analysis and experiments that involve test variables or systems that are to be calibrated for future measurements.

What are certified reference materials and how are they obtained?

Every lab application or measurement requires a standard against which any reading is compared. Only then can the results be corroborated and confirmed to be accurate. There are several national and international standards for primary and secondary references. These standards are known as certified reference materials, and their construction and calibration is carried out under stringent conditions. These are usually available to purchase, and it is easier to perform lab experiments using these certified reference materials, than create accurate materials of one's own.

Reference materials cannot easily be produced in one's own lab. There are several standards and guidelines to follow, such as the ISO Guide 34 for this purpose. Calibration laboratories are usually the arrangements where this can be developed. Unless the standard under consideration is created correctly, every reading and result performed with the material can yield errors.

Types of Certified Reference Materials available

Instrument qualification of spectroscopy equipment is carried out in the UV and visible spectrum. Certified reference materials are available in both liquid and vapour reference materials as well for the purpose. Distortion of optical surfaces is controlled to a highly precise extent with these standard materials. Techniques followed for construction are highly detailed and with high accuracy and quality checks at every stage.

In order to qualify an instrument for the intended function, there are several accompanying documents that are available with the device. These documented collections of activities come in various forms and have different types of information included. Operational qualification documents contain information that confirms the device will operate as per operational specifications in a selected environment. Similarly performance specifications demonstrate how a material performs under actual conditions of use. The information in these documents is compiled after extensive laboratory and real-world application testing, so the user can depend on this information for planning the use of the material. Continued performance qualification will also have to be carried out on an ongoing basis, to ensure that the device is capable of continued efficient performance over time and in different environmental conditions.
