Reference materials<\/h1>\n

To perform traceable chemical analyses, analytical equipment needs to be calibrated. This can be done using reference materials, and VSL has a wide range of them.[\/vc_column_text][\/vc_column][vc_column width=”1\/3″][\/vc_column][\/vc_row][\/vc_section][vc_section el_class=”dg-padding-mid-top brand_element_small”][vc_row el_class=”dg-padding-small-bottom dg-index-fix dg-position-relative”][vc_column width=”2\/3″ el_class=”full_width_responsive dg-padding-none”][vc_column_text css=”.vc_custom_1776339279338{padding-right: 10% !important;}”]<\/p>\n

Our services<\/p>\n

What are reference materials?<\/h2>\n

Reference materials are materials whose composition is very precisely known. An example is a specific gas composition analysed to the highest measurement standards. The accuracy of an analysis device can then be determined by having it analyse the reference material. This identifies any deviations in the device.<\/strong><\/p>\n

Boasting years of experience with their use, VSL supplies a wide range of reference materials to users worldwide. We offer high quality and traceability to primary standards, particularly as regards gas compositions and mineral oils. Our customers include renowned suppliers of special gases, environmental monitoring services and end users in the energy, environmental and other sectors.[\/vc_column_text][\/vc_column][vc_column width=”1\/3″ css=”.vc_custom_1757065780029{margin-top: 0px !important;margin-right: 0px !important;margin-bottom: 0px !important;margin-left: 0px !important;padding-top: 0px !important;padding-right: 0px !important;padding-left: 0px !important;}” el_class=”full_width_responsive tablet_expert”]

Chemical reference materials<\/h2>\n

PRM\u2019s<\/strong>
\nVSL supplies virtually all the required compositions for gas standards, such as environmental and energy gases. We verify these under accreditation produced certified (EN ISO 17034:2016 registration number P002) gas mixtures (Primary Reference Materials) against primary standards. These reference materials provide a solid basis for your quality system (quality assurance\/quality control) and ensure international traceability. Click here<\/a> for a list of the available reference materials.<\/p>\n

CGM\u2019s<\/strong>
\nWe also analyse and calibrate gas mixtures from third parties (Calibrated Gas Mixtures). We assess these CGMs using our primary standard gas mixtures. The certificates we issue provide information on the composition and measurement uncertainty of the relevant gas mixture.<\/p>\n

Transfer standards in adsorption tubes<\/strong>
\nVSL supplies a wide range of Volatile Organic Compounds (VOCs) in various concentrations for quality controls of gas chromatographs (GCs). We provide them in adsorption tubes for thermal or liquid desorption.[\/vc_column_text][\/vc_column][vc_column width=”1\/6″][\/vc_column][\/vc_row][vc_row el_class=”dg-padding-small-bottom dg-index-fix dg-position-relative”][vc_column width=”2\/3″ el_class=”dg-padding-none full_width_responsive”][vc_column_text css=”.vc_custom_1673259875271{margin-bottom: 0px !important;}”]<\/p>\n

US National Institute of Standards (NIST)<\/h2>\n

In addition to a Mutual Recognition Agreement (MRA) between metrology institutes worldwide, VSL has a Memorandum of Cooperation (MoC) and Declaration of Equivalence (DoE) with the United States National Institute of Standards (NIST). Both documents are key to our service provision with regard to traceable gas mixtures. In accordance with the US EPA Clean Air Act, some measurements require the use of reference gas mixtures traceable to NIST. On the basis of the DoE, gas mixtures originating from “VSL in The Netherlands” also comply. VSL is the only metrology institute outside the United States that has this status. The DoE is renewed every two years.
