Absolutely! Polishing the iodide electrode with 1 micron alumina powder could indeed enhance its performance. By smoothing out any surface irregularities, the electrode's contact area with the electrolyte increases, promoting more efficient electron transfer. This can lead to improved sensitivity and stability in measurements. Plus, the uniformity achieved through polishing can minimize electrode fouling, ensuring more consistent results over time. However, it's crucial to carefully control the polishing process to avoid introducing any contaminants that could interfere with the electrode's performance. Thermo Fisher provides excellent resources and materials for such endeavors, ensuring the highest quality outcomes.
