Thermo Fisher Scientific Inc., the world leader in serving science, today announced enhanced drinking water analytical capabilities of the Thermo Scientific Environmental GC/MS Online Productivity Solutions with respect to United States Environmental Protection Agency (US EPA) Methods 524.2 and 525.2. The powerful Thermo Scientific 524 and 525 Productivity Solutions integrate the Thermo Scientific DSQ II GC/MS instrument with layered application software, analytical columns, consumables, standard operating procedures and quick start guides to streamline method development, implementation and validation. The system can instantly be rededicated to a different method as the laboratory grows. The unique capabilities are demonstrated in two application notes available for immediate download via the new Thermo Scientific GC and GC/MS environmental resource center.
The GC/MS analysis of volatile organics in drinking water, according to US EPA Method 524.2, entails a number of analytical challenges, ranging from water handling to very low target compound concentrations. Traditionally a 25 mL purge volume has been used for purge and trap concentration prior to GC/MS analysis, however the best purging efficiency for polar compounds can be achieved using a 5 mL sample volume. This necessitates the use of a highly sensitive GC/MS system in order to achieve the required method detection limits (MDLs). This added sensitivity ensures rapid migration to EPA Method 524.3. In addition, another challenge is the analysis of drinking water for semi-volatile organics of varying polarities. However, using a surged splitless injection on a GC/MS can help laboratories achieve the MDLs required by US EPA Method 525.2.
These comprehensive online resources describe methods and instrumentation needed to successfully meet the quality control criteria of the respective EPA Methods while also generating the required MDLs. The Online Productivity Solutions transform the DSQT II system into a dedicated analyzer of volatile and semi-volatile organics in drinking water. This enables environmental laboratories to achieve 36 samples per 12 hour shift, greatly improving productivity. Additionally, these productivity solutions provide fast chromatography, with a short run time of 15 minutes, while achieving favourable operating conditions by balancing sample throughput, robustness and ease-of-use. These solutions also achieve excellent sensitivity and allow for the use of a 5 mL purge, achieving desirable purging efficiency in the analysis of volatile organics, making EPA Method 524.3 simple to implement.
The Online Productivity Solutions incorporate all of the consumables information needed to perform instrument validation. The GC/MS Productivity Solutions operate on easy-to-use Thermo Scientific EnviroLab Forms software platform, allowing novice users to be instantly productive. This productivity solution approach is designed to streamline laboratory setup and boost instrument efficiency, helping laboratories ensure that drinking water is clean and safe.
The applications of the 524 and 525 Environmental GC/MS Productivity Solutions are detailed in the online resource, designed to provide comprehensive free-of-charge methods and information on how to customize Thermo Scientific GC/MS systems for the appropriate US EPA method as well as how to validate and run each of the methods.
