 Reagents Search: As a researcher, you mine for data and knowledge. Surely you have experienced this: you know exactly what you’re looking for, but you have only a limited amount of time to find it!
To accelerate the search for chemical reagents for your analytical application, Sigma-Aldrich has launched a new search engine for analytical reagents. Search by any one of the following – product name, product number, CAS number, or molecular formula – and you will see matching products in the displayed results, with the ability to further refine the results by product properties such as grade, purity, or a choice of attributes specific to your research application.
Our new Reagents Search feature encompasses all Sigma-Aldrich products within these product lines:
- Analytical Reagents & Solvents
- Chromatography/CE Reagents
- Derivatization Reagents
- Titration & Karl Fischer Reagents
- Microscopy Reagents
- Gravimetric Reagents
- Trace Analysis Reagents

 Petrochemical Industry Air Pollution: Increasing global demands of transportation and industrial innovation have resulted in greater production of petroleum distillates and by-products. Employees who work within this industry and residents of neighboring communities are at risk for exposure to chemical compounds that are detrimental to health and safety.
Supelco offers the most comprehensive range of carbon-based adsorbents (Carbopack™ and Carbotrap™), carbon molecular sieves (Carboxen™), as well as innovative radiello® passive sampling products to help analysts meet their difficult sampling and analysis needs.
Petrochemical air monitoring requires a diverse range of media for sampling contaminants such as: BTEX, PAHs, Hydrogen Sulfide, Sulfur Dioxide, Mercury and more. Regulatory agencies such as OSHA and NIOSH usually specify carbon-based sorbent tubes and select filters.
Supelco offers both active and passive sampling media devices, with our adsorbent technology inside, to collect and measure these contaminants. We also offer chemical reference standards, capillary GC columns, analytical reagents and solvents to complete the analysis steps indicated by agency methods.
Visit the Petrochemical Industry air sampling page for more information.
