About RTC

 


Traceable Secondary Pharmaceutical Reference Standards

RTC Pharmaceutical Reference Standards (PRS) are certified reference materials (CRMs) manufactured and certified in accordance to ISO Guide 34:2009 and ISO/IEC 17025:2005. These standards are secondary reference materials that are qualified to and traceable to the major pharmacopoeia standards. RT Pharma PRS products represent the first commercially available harmonized pharmaceutical standards available. Every PRS product is supplied with a Certificate of Analysis (COA), which is among the most extensive in the industry. PRS products are not only economical but enhance quality by providing larger quantities of material for measurement.

Reference Materials for Microbiological Testing

Microbiological products cover QC testing for your laboratory. RTC Microbiological products are certified reference materials (CRMs) manufactured and certified in accordance to ISO Guide 34:2009 and ISO/IEC 17025:2005.

RTC's Vitroids™ technology for stabilizing micro organisms minimizes the stress during the storing process. This technology offers significant advantages over other stabilization technologies.

Unlike other microbiological standards, Vitroids offer:
1) Enhanced long term stability
2) High organism viability
3) No Recovery or Pre-incubation time

This means RTC's products are easier and faster to use, saving the busy laboratory analysts time. These products offer users enhanced flexibility and usability and are easily adaptable to any laboratory SOPs in a wide variety of applications - Environmental, Pharmaceutical, Medical, Food and Water.

Many of RTC's Vitroids (RQC) microbiological standards are offered as Quality Control microbiology products under the American Type Culture Collection (ATCC®) Licensed-Derivative® program. The ATCC Licensed Derivative emblem signifies ATCC-derived products are endorsed by ATCC. Products displaying the emblem are the only ones for which the quality of the ATCC ingredient can be properly assured.

ATCC does not endorse products including ATCC ingredients from companies that are not members of the LDP program. Vitroids products utilize a proprietary patented technology to stabilize bacterial organisms in a suspended state with very minimal viability loss.

Environmental Matrix Reference Materials

A certified reference material is defined as a reference material, characterized by a metrologically valid procedure for one or more specified property, its associated uncertainty and a statement of metrological traceability.

RTC is accredited to certify CRMs and has become the world leader in the production and certification of soil and sediment Certified Reference Materials. All CRMs are either natural matrix materials or natural matrices in which selected analytes have been fortified to give the resultant CRM an analyte profile that meets the needs of the market.

In certification of the RTC CRMs, data developed from multi-laboratory analysis is supported by in-house data, and a robust statistical program is used. Most CRMs are method specific; the certificate shows a confidence interval, uncertainty, prediction value, and expanded uncertainty, in addition to the mean value and standard deviation from the mean.

Certified Reference Material development started at RTC more than 20 years ago. RTC has collected soils and solid wastes from contaminated sites around the United States to produce real-world CRMs for the USEPA. Since then, the product range has grown and now includes a wide range of natural-matrix CRMs. RTC Environmental Matrix Reference Materials are certified reference materials (CRMs) manufactured and certified in accordance to ISO Guide 34:2009 and ISO/IEC 17025:2005.
