Abstract:
100 % polyethylene glycol (PEG) columns, also known as WAX columns, are polar GC columns used for a wide variety of applications, such as industrial chemicals and petrochemicals analyses. Despite their popularity however, traditional WAX columns are often limited by their maximum operating temperatures. This is in part due to the high bleed, degradation and decreased thermal stability of PEG polymers at elevated temperatures. The Agilent J&W DB-HeavyWAX is a WAX-type column engineered to overcome these limitations. DB-HeavyWAX provide extended temperature limit, up to 280 °C isothermal and 290 °C programmed and increased thermal stability, increasing injection-to-injection retention time reproducibility and column lifetime. In this research work, we show how a higher upper temperature limit allows for faster analysis, and better retention time reproducibility while minimizing possibility of carryover from sample to sample.
