Ensure Accuracy and Increase Productivity for Semivolatiles
Semivolatiles analysis is a core test in many environmental labs, but consistently generating reliable results is challenging because target analyte lists are broad and include different types of reactive compounds. To help labs ensure accurate results and increase sample throughput, Restek has created a new portal for GC semivolatiles analysis that provides quick, easy access to proven solutions.
High-Performance Split Injection Method for Semivolatiles
In this split injection method, excellent results were obtained for a wide range of troublesome semivolatile compounds, even those that are reactive or difficult to resolve. We used a highly inert Rxi-SVOCms column because it is designed specifically for semivolatiles analysis and consistently produces good peak shapes, separations, and responses, even for challenging analytes.
How Liner Choice Can Increase Productivity for Semivolatiles Analysis
Narrow-bore columns can speed up run times, but they are limited by sample introduction. Compared to typical liners, intermediate-volume (IV) liners give narrow-bore column users more flexibility and allow more sample to be injected, without risking backflash or poor peak shapes. Read on to see how IV liners improved semivolatiles peak characteristics, allowing the benefits of narrow-bore columns to be realized.
Speed Up Semivolatiles Analysis Without Sacrificing Critical Separations
With proper method translation, separation of critical semivolatile compounds, such as indeno[123-cd]pyrene and dibenz[ah]anthracene, can be maintained while reducing analysis time by ~30%. In this blog, we use Restek’s free EZGC method translator to properly convert method parameters from a 16-minute run on a 30 m x 0.25 mm x 0.25 µm column to a 11.5-minute run on a 20 m x 0.15 mm x 0.15 µm column.
