Agilent J&W DB-WAX 125-7032 GC column: analytical performance and universal compatibility
The Agilent J&W DB-WAX 125-7032 capillary column is a high-precision component designed to meet the requirements of gas chromatography analyses requiring high polarity. Thanks to its DB-WAX phase, known for its strong polar interactions, this column provides optimal separation of oxygenated compounds such as alcohols, aldehydes, organic acids and esters, which are often difficult to distinguish with low-polarity columns.
Its 30-metre-long fused silica tube is carefully treated to ensure maximum inertness and excellent thermal stability. The internal diameter of 0.53 mm, coupled with a film thickness of 1.00 µm, provides a good balance between loading capacity, separation efficiency and compatibility with a wide range of samples. This type of configuration is ideal for high-throughput analyses or for high-concentration compounds without compromising resolution.
The J&W DB-WAX 125-7032 column is mounted on a 7-inch cage, a widely adopted format compatible with most chromatograph ovens, including the Agilent 5890, 6890, 7820, 7890, 8860 and 8890 series. It is also perfectly suited for other non-Agilent GC systems, provided that the oven dimensions are equivalent, making it a highly versatile solution for multi-system laboratories.
This model is validated for a wide range of standard analytical methods, including ASTM D3329, D3687, D2804 and D3695, as well as EPA 8430 and USP 401. In addition, it complies with several USP designations (G14, G15, G16, G20, G39, G47), making it ideal for use in the pharmaceutical, environmental and petrochemical industries, where regulatory compliance is paramount.
The operating temperature ranges from 20°C to 230°C (and up to 240°C at peak), providing a wide analysis window for volatile and semi-volatile compounds. This wide temperature range ensures great flexibility for complex temperature programmes.
The Agilent J&W DB-WAX 125-7032 column combines high polarity, universal compatibility and regulatory compliance with robustness, reproducibility and exceptional chromatographic quality. It is the optimal choice for laboratories seeking a reliable column for demanding and standardised analyses.
