Not satisfied with the options available to us, Restek started our own standards laboratory to support our rapidly growing column business and our applications chemists. We have since expanded our standards manufacturing capabilities to cater to our entire global customer base to help&nbsp;you meet the needs of tomorrow\u2019s emerging analyses.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:30%\">\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"700\" height=\"460\" src=\"https:\/\/discover.restek.com\/wp-content\/uploads\/figure-article-GNBR1845B-01.jpg\" alt=\"\" class=\"wp-image-21718\" title=\"-\" srcset=\"https:\/\/discover.restek.com\/wp-content\/uploads\/figure-article-GNBR1845B-01.jpg 700w, https:\/\/discover.restek.com\/wp-content\/uploads\/figure-article-GNBR1845B-01-300x197.jpg 300w\" sizes=\"auto, (max-width: 700px) 100vw, 700px\" \/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<p><strong>State-of-the-Art Facilities:<\/strong> Our ISO-accredited laboratories in Bellefonte, Pennsylvania, feature cutting-edge environmental controls and web-based monitoring systems to help guarantee the safety of our personnel and the performance of our reference standards. Creating a new lab space from the ground up in 2008, and then expanding it by 33% in 2014, has allowed us to capitalize on work triangles and cross-training to bolster the strength of our bench chemists, increase throughput, and better manage costs\u2014so you can get a better-quality product faster and with less impact on your budget.<\/p>\n\n\n\n<p><strong>Automated Production System:<\/strong> From formulation through production, testing, and the generation of certificates, Restek\u2019s production process is automated to engineer out variability and error. All raw materials are barcoded to eliminate technician calculations and downstream data entry\u2014a must when you\u2019re managing multiple lots of more than 4200 neat compounds! With a simple scan of a label, our proprietary system calculates weights, then validates and transfers the exact amount of material needed for the given mix. To remove another common source of human error, our data pack builder programmatically generates documentation every time a new batch is produced instead of our chemists creating it manually.<\/p>\n\n\n\n<p><strong>Robust Product Development:<\/strong> Every standard in the Restek catalog goes through feasibility, stability, scale-up, and operational stage gates; a red flag at any checkpoint stops development until it\u2019s resolved. We have also added the ability to synthesize our own high-purity neat materials to minimize our exposure to material shortages and purity issues in the marketplace. To ultimately determine which organic reference standards will make it into the pipeline, our experts closely monitor the shifting legislative and regulatory landscape around the globe and actively engage with our customers. Once a product is chosen, a veteran chemist formulates a stable reference standard containing an ideal mix of compounds and concentrations based on our years of experience and the lessons learned from creating the 50,000+ batches of standards that have left our facility over 30+ years.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column has-background is-layout-flow wp-block-column-is-layout-flow\" style=\"background-color:#e5f7fa;padding-top:10px;padding-right:20px;padding-bottom:10px;padding-left:20px\">\n<p><em>\u201cAs we were looking for quality and reliability, Restek appeared to be the obvious choice [for custom standards].

Restek has also maintained ISO 9001 registration since 1994. Put another way, almost all of our stock reference standards are officially recognized as being manufactured and QC tested under the world-class quality standards established by the International Organization for Standardization (ISO). Many laboratories are required to purchase CRMs to satisfy their own ISO requirements, but even if you are not, you can still benefit from the performance, reliability, and consistency of Restek certified reference materials.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><em>Learn more about Restek\u2019s ISO quality credentials and view our certificates (including scopes of accreditation) <a href=\"https:\/\/discover.restek.com\/iso-quality-credentials\/\">here.<\/a> <\/em><\/h4>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-link-color wp-elements-f81e13a086144df95e5b3495c46b6b9f\" style=\"color:#0188d0\">CUSTOM FLEXIBILITY<\/h3>\n\n\n\n<p>Our labs develop 200+ new custom standard formulations each month. In fact, more than 1\/3 of the ampuls that leave our facility are custom-ordered reference standards, and almost all of them are certified reference materials (CRMs). That\u2019s because, unlike some manufacturers, Restek\u2019s ISO scopes of accreditation cover not only our catalog standards but also your custom orders. All custom standard requests are reviewed by our experienced team of formulations chemists to confirm feasibility, to make you aware of any chemical compatibility concerns, and to detail our recommendations for the most robust formulation possible. In short, we give you the flexibility to order Restek standards to your exacting specifications\u2014and the confidence of knowing that you will receive the same top-quality, highly stable product whether it\u2019s a stock, off-the-shelf standard, or a one-of-a-kind, custom-formulated solution.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><em>For less waiting and lower cost, visit <a style=\"color:#0d7bc4;\" href=\"https:\/\/www.restek.com\/custom-reference-standard-request-form\" data-type=\"link\" data-id=\"https:\/\/www.restek.com\/custom-reference-standard-request-form\" target=\"_blank\" rel=\"noopener\">https:\/\/www.restek.com\/custom-reference-standard-request-form<\/a>&nbsp;to immediately request a custom standards quote!<\/em><\/h4>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-link-color wp-elements-a0bf43c5605ab552a6810ba91975c8e0\" style=\"color:#0188d0\">EASY-TO-FIND DOCUMENTATION<\/h3>\n\n\n\n<p>Every analyst and every lab is different.
