The Thermo Scientific Environmental GC/MS Online Productivity Solutions provide drinking-water analysis in compliance with US 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 be instantly 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 centre at the company's website.
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 25ml 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 5ml 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 DSQ II system into a dedicated analyser of volatile and semi-volatile organics in drinking water.
This enables environmental laboratories to achieve 36 samples per 12-hour shift, which improves 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 5ml 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 electronic methods and quick-start guide can be automatically downloaded directly from the company's website to a local computer.
The GC/MS Productivity Solutions operate on the easy-to-use Thermo Scientific Envirolab Forms software platform, allowing novice users to be instantly productive.
This productivity solution approach streamlines laboratory setup and boosts instrument efficiency, helping laboratories ensure drinking water is clean and safe.
