5 What makes RTC different? 2x the amount for PTs RTC provides most ampuled water PTs in duplicate. This allows you to run multiple methods or have more analysts perform the PT. It also covers your laboratory in case of the accidental mishap. If you do not use the second vial, it becomes a QC sample once the study is closed. Easily Accessed Documentation Online Certificates of Analysis, MSDS, and Proficiency Testing reporting documents can easily be viewed and downloaded through our website. RTC Quick-Turn Studies RTC does not charge extra for our Quick-Turn PT studies. Our Quick-Turn studies are always the same price as our scheduled PTs. The World Standard Standardized QC Pricing RTC has a straightforward and logical pricing scheme for its QC products. Our QCs are always 30% less than our PT products. Certificates of Excellence Laboratories that demonstrate excellence throughout the year in proficiency testing are issued a certificate suitable for display and presentation to your customers. Analyst Certificates of Proficiency Laboratories that enter data online are able to generate and print a certificate of proficiency for each PT the analyst has successfully performed. These certificates represent valuable records of training and performance for laboratory audits. 2 First Choice for Quality

7 Permission-based access for multiple users within your organization: Set up each analyst or work group with data entry permission and they can enter their data directly. The Quality Manager or administrator has a visual interface to monitor data entry and deadlines. Easy access to results and reports: View your study evaluation in PDF, spreadsheet or HTML format. Configure reporting for your laboratory: Add the methods used by your laboratory the first time, and all future studies will default to these methods. Easily add new methods in the future, if required. Enhanced data reporting: Need to report one analyte to one accreditor and another analyte to a different accreditor? Easily report all of your study to one or multiple accreditors, or pick and choose which results should be reported. Enhanced usability and online support: With our interface and enhanced navigation, you can find information and enter data faster. If you have a question, simply click the help button found on each page to find the answers to common questions. Keep your data secure: With our SSL security, password encryption and individualized permission-based access, you can rest easy knowing that your data is safe. Advanced product searching: Find the right product quickly and easily with our online product comparisons. Simply enter the analytes you require, and our system will find the products that best meet your needs. 4 First Choice for Quality

10 Laboratory Proficiency Testing Programs RTC has been producing environmental Laboratory Proficiency Testing Programs for more than 20 years. Regular shipments of more than 20,000 PT standards a year are sent to over 2,500 participants world wide. Features that make RTC unique and give you the RTC Advantage include the following: Most water Proficiency Test Samples are supplied in duplicate. The duplicate can be used to report additional methods or retained as a QC standard, using the study data values. Advanced Tracking Methods, Analysts, Accreditation, and Equipment can be reported for the same analyte at no extra charge. Evaluation reports can be sent to your Accreditation Authority (AA) for no additional charge.
