Title: Innovations by Nathan James Wrench
Introduction
Nathan James Wrench is a prominent inventor based in Bishops Castle, GB, known for his significant contributions to the field of scientific instrumentation. With a total of two patents to his name, Wrench focuses on improving the capabilities of evaporative light scattering detectors.
Latest Patents
Wrench's latest innovations include two notable patents:
1. **Evaporative Light Scattering Detector** - This improved apparatus addresses the challenges faced by conventional detectors when working with volatile samples. Traditionally, complete evaporation of the mobile phase (solvent) is hindered by the saturation of vapor at lower temperatures, while higher temperatures lead to an undesirable early evaporation of samples without aerosol formation. Wrench's solution involves introducing a dry evaporator gas to the sample prior to its entry into the drift tube. This method allows for the complete evaporation of the solvent even at low temperatures.
2. **ELSD Diffuser** - This design features an evaporative light scattering detector with a specialized solvent nebulizer that creates an atomized spray of the solute solvent solution. The heated evaporation chamber is equipped with a diffuser trapping device, made from coiled stainless steel ribbon, which enhances the surface area and ensures efficient evaporation of the solvent. Positioned strategically within the evaporation chamber, this device prevents larger particles from moving further down, thereby maintaining the integrity of the detection process.
