Acid-Resistant Sputtered Metal Coatings for SPME Applications ID: 2020-062

This technology introduces an innovative method for applying acid-resistant, thin metal coatings to enhance the durability and functionality of solid phase microextraction (SPME) devices.

Technology Overview

The invention involves the application of a very thin layer of metal, such as titanium or chromium, onto a stainless steel surface before adding a sputtered, porous silicon coating. This process significantly improves the adhesion and stability of the silicon layer, especially during the functionalization with chlorosilanes, a process that typically undermines the integrity of silicon coatings due to acid production. Utilizing physical vapor deposition techniques, this method ensures the robustness of the silicon layer, enhancing the performance and reliability of SPME devices.

Key Advantages

• Enhanced adhesion and stability of silicon coatings on stainless steel substrates
• Increased resistance to acid damage during the functionalization process
• Improved performance and reliability of SPME devices
• Utilization of standard physical vapor deposition techniques for easy integration into existing manufacturing processes

Problems Addressed

• Instability of sputtered silicon coatings on stainless steel during derivatization with chlorosilanes
• Detachment of silicon coatings due to hydrochloric acid production

Market Applications

• Enhancement of coated blade spray (CBS) technologies
• Improvement of 'Arrow'-type SPME devices for better sample collection and analysis
• Potential applications in various analytical and chemical engineering fields requiring durable coated surfaces
