| 203-821-696 | Satisfying ASTM D8396 Requirements Paradigm GCxGC-FID This application note describes how to use a simple workflow with the LECO Paradigm system to fulfill the requirements of the ASTM D8396 test method to quantitatively determine mass % of total n-paraffins, iso-paraffins, naphthenes, 1-ring aromatics, and 2-ring aromatics using reverse-fill flush flow modulated comprehensive two-dimensional gas chromatography–flame ionization detection (GCxGC-FID). Understanding of bulk composition is crucial for fast-track certification of synthetic aviation fuels as outlined in ASTM D4054, and the more accurate group-type analysis results provided by GCxGC assist with streamlining the acceptance process. |
| 203-821-695 | CX300 Sectioning for Weld Evaluation For numerous applications, it is necessary to measure the quality of a weld, and there are several methods for doing so. Making a sacrificial test weld and using a microscope to measure the weld's critical areas is a popular technique. This procedure may require a lot of time and resources. However, by skipping the mounting and polishing stages, the work can be kept more efficient. Bypassing those phases in the metallographic sample preparation procedure, this "Cut and Etch" technique yields accurate readings. |
