Silicone Molecular Weight Testing

A client seeks a laboratory capable of conducting molecular weight testing on multiple silicone materials used in medical components. The items include catheter silicone, cannula silicone, tipping silicone (defective), and pure cannula silicone. Due to limited material availability, especially from the cannula tip (less than 0.1 mg), the lab must confirm whether accurate molecular weight analysis is feasible with such small sample sizes. Please advise on method suitability, sensitivity thresholds, and provide a quote including turnaround time and submission guidelines.
