Restek Reference Standards

Build a rock-solid analytical foundation with Restek reference standards:

• ISO-Recognized Quality
• Full-Service Custom Flexibility
• Easy-to-Find Documentation

Crack open the best organic reference standards in the industry.

Your business, your accreditations, your reputation, and even your livelihood....they are all supported by your reference standards. Those tiny ampuls are hugely important for your ability to identify analytes and validate methods. Whether you are processing environmental samples or petroleum products, testing pharmaceuticals or food, your laboratory cannot stand without a trusted source of high-quality organic reference standards, reference materials (RMs), and certified reference materials (CRMs).

Even with Restek’s industry-leading GC and LC columns, sample prep materials, and accessories, you won’t get the results your customers demand without support from the finest reference standards available. We have an experienced team working two shifts per day to make sure that Restek reference standards offer you the extended shelf life, unsurpassed stability, and outstanding chromatographic performance you need to get your work done right.

State-of-the-Art Facilities: 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—so you can get a better-quality product faster, and with less impact on your budget.

Automated Production System: From formulation through production, testing, and the generation of certificates, Restek’s production process is automated to engineer out variability and error. All raw materials are barcoded to eliminate technician calculations and downstream data entry—a must when you’re 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.

Robust Product Development: 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’s 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.

 

Rigorous Screening Processes: Restek does not simply accept purity as reported by our vendors. Our Quality Control (QC) lab fully characterizes all incoming raw materials to confirm the chemical identity and purity of both mixture components and solvents, adjusting for anything less than 99%. All developed formulations are subjected to a thorough review of accuracy, compatibility, and solubility by a second Restek chemist, and during production, compound compatibility is continuously scrutinized. We also conduct ongoing, long-term stability studies to ensure reliability and precise shelf-life reporting.

Why Should You Switch to Restek Reference Standards?

Restek was founded by chemists and has succeeded by providing fellow chemists like you with the right tools for the job. When it comes to the time-consuming labor of mixing reference standards—not to mention sourcing, verifying, and storing your own raw materials—Restek’s internationally recognized experts have already done the work for you. Turn to Restek for the ISO quality, custom flexibility, and easy-to-find documentation you require to fit your workflows and trust your results.

ISO QUALITY

Over 98% of the Restek-manufactured reference standards in our catalog are certified reference materials, and that includes both singles and multicomponent mixes. 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.

CUSTOM FLEXIBILITY

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’s because, unlike some manufacturers, Restek’s 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—and the confidence of knowing that you will receive the same top-quality, highly stable product whether it’s a stock, off-the-shelf standard or a one-of-a-kind, custom-formulated solution.

EASY-TO-FIND DOCUMENTATION

Every analyst and every lab is different. That’s why Restek exclusively offers three levels of fully ISO-compliant documentation for our reference standards.

• Certificate of Analysis gravimetric includes all raw material information, lot numbers and purity, isomer ratios for isomeric compounds, and calculated concentration(s). Associated uncertainties are also included for Certified Reference Materials (CRMs).

• Certificate of Analysis chromatographic includes all raw material information, lot numbers and purity, isomer ratios for isomeric compounds, and calculated concentration(s). Associated uncertainties are also included for Certified Reference Materials (CRMs). Additionally, a single sample is withdrawn from the packaged units and is tested via an appropriate technique to verify mixture composition. A chromatogram of the analyzed standard, with each peak identified, is included on the certificate.

• Certificate of Analysis chromatographic plus includes all raw material information, lot numbers and purity, isomer ratios for isomeric compounds, and calculated concentration(s). Associated uncertainties are also included for Certified Reference Materials (CRMs). Additionally, a sample of the packaged units is analyzed in triplicate, and the peak areas are statistically compared to a second lot—either a previous lot (if available) or a freshly produced independent second lot. A chromatogram of the analyzed standard, with each peak identified, is included on the certificate. Plus, a detailed data pack containing the product certificate, all quantitative assay data and statistics, and the Reference Material Batch Record are available at www.restek.com/documentation

Electronic and archived on Restek’s servers, certificates as well as safety data sheets (SDSs) for your stock or custom standard are available any time and from anywhere. In addition, SDSs for stock standards are automatically prepared in multiple languages, and non-English translations can be requested for custom reference standards. You no longer need filing cabinets and boxes full of paper... only an Internet connection. And, your information is protected because a lot # is required to view certificates for all custom standards.

For even more convenience, every Restek reference standard offers personalized, instant access to documentation. Simply scan the QR code on your ampul storage tube label to go directly to the certificate of analysis for your specific standard and lot # on Restek.com. In addition, large pictograms on our GHS-compliant labels better promote safety in your lab, helping you meet OSHA, CLP, and other government requirements.
