Sievers® Certified Reference Materials (Sievers Standards) represent a comprehensive offering of ready-to-use TOC and conductivity standards for calibration, linearity and USP system suitability applications. The large scale production capabilities of GE Analytical Instruments can provide substantial cost advantages as well as time savings compared to in-house preparation. And with our expertise in the preparation and storage of standards, you can rely on both the accuracy and extended shelf life of standards, even at low concentrations. Sievers Standards are guaranteed. If they do not meet or exceed stated specifications, they will be promptly replaced at no cost to you.

Standards delivery programs can also be customized to fit your needs, whether you require regularly scheduled shipments or overnight delivery. If you would like to satisfy your annual requirements for system suitability by using a single purchase order, consider our annual standards kits. The standards are shipped to you on a regular schedule throughout the year for your convenience, and to help ensure optimum instrument operation.
